Subject: [PATCH] fw_env: fix reading NVMEM device's "compatible" value
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Call to fread() was changed to check for return value. The problem is it
can't be checked for returning 1 (as it is) to determine success.
We call fread() with buffer size as "size" argument. Reading any
"compatible" value shorter than buffer size will result in returning 0
even on success.
Modify code to use fstat() to determine expected read length.
This fixes regression that broke using fw_env with NVMEM devices.
Fixes: c059a22b7776 ("tools: env: fw_env: Fix unused-result warning")

Subject: [PATCH] list: don't backport list_count_nodes()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
It's redundant in OpenWrt as it backports it on its own. This fixes:

Subject: [PATCH] r8152: add USB device driver for config selection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Subclassing the generic USB device driver to override the
default configuration selection regardless of matching interface
drivers.
The r815x family devices expose a vendor specific function which
the r8152 interface driver wants to handle. This is the preferred
device mode. Additionally one or more USB class functions are
usually supported for hosts lacking a vendor specific driver. The
choice is USB configuration based, with one alternate function per
configuration.
Example device with both NCM and ECM alternate cfgs:

A problem with this is that Linux will prefer class functions over
vendor specific functions. Using the above example, Linux defaults
to cfg #2, running the device in a sub-optimal NCM mode.
Previously we've attempted to work around the problem by
blacklisting the devices in the ECM class driver "cdc_ether", and
matching on the ECM class function in the vendor specific interface
driver. The latter has been used to switch back to the vendor
specific configuration when the driver is probed for a class
function.
This workaround has several issues;
- class driver blacklists is additional maintanence cruft in an
unrelated driver
- class driver blacklists prevents users from optionally running
the devices in class mode
- each device needs double match entries in the vendor driver
- the initial probing as a class function slows down device
discovery
Now these issues have become even worse with the introduction of
firmware supporting both NCM and ECM, where NCM ends up as the
default mode in Linux. To use the same workaround, we now have
to blacklist the devices in to two different class drivers and
add yet another match entry to the vendor specific driver.
This patch implements an alternative workaround strategy -
independent of the interface drivers. It avoids adding a
blacklist to the cdc_ncm driver and will let us remove the
existing blacklist from the cdc_ether driver.
As an additional bonus, removing the blacklists allow users to
select one of the other device modes if wanted.

Subject: [PATCH] r8152: avoid to change cfg for all devices
The rtl8152_cfgselector_probe() should set the USB configuration to the
vendor mode only for the devices which the driver (r8152) supports.
Otherwise, no driver would be used for such devices.

Subject: [PATCH] r8152: Rename RTL8152_UNPLUG to RTL8152_INACCESSIBLE
Whenever the RTL8152_UNPLUG is set that just tells the driver that all
accesses will fail and we should just immediately bail. A future patch
will use this same concept at a time when the driver hasn't actually
been unplugged but is about to be reset. Rename the flag in
preparation for the future patch.
This is a no-op change and just a search and replace.

Subject: [PATCH] nvmem: Do not expect fixed layouts to grab a layout driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Two series lived in parallel for some time, which led to this situation:
- The nvmem-layout container is used for dynamic layouts
- We now expect fixed layouts to also use the nvmem-layout container but
this does not require any additional driver, the support is built-in the

Subject: [PATCH] of: device: Export of_device_make_bus_id()
This helper is really handy to create unique device names based on their
device tree path, we may need it outside of the OF core (in the NVMEM
subsystem) so let's export it. As this helper has nothing patform
specific, let's move it to of/device.c instead of of/platform.c so we
can add its prototype to of_device.h.

Subject: [PATCH] nvmem: Move of_nvmem_layout_get_container() in another header
nvmem-consumer.h is included by consumer devices, extracting data from
NVMEM devices whereas nvmem-provider.h is included by devices providing
NVMEM content.
The only users of of_nvmem_layout_get_container() outside of the core
are layout drivers, so better move its prototype to nvmem-provider.h.
While we do so, we also move the kdoc associated with the function to
the header rather than the .c file.

move the main nvmem_device structure in an internal header, only
available to the core. This way all the additional code can be added in
a dedicated file in order to keep the current core file tidy.

From fc29fd821d9ac2ae3d32a722fac39ce874efb883 Mon Sep 17 00:00:00 2001
From: Miquel Raynal <miquel.raynal@bootlin.com>

Subject: [PATCH] nvmem: core: Rework layouts to become regular devices
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Current layout support was initially written without modules support in
mind. When the requirement for module support rose, the existing base
was improved to adopt modularization support, but kind of a design flaw
was introduced. With the existing implementation, when a storage device
registers into NVMEM, the core tries to hook a layout (if any) and
populates its cells immediately. This means, if the hardware description
expects a layout to be hooked up, but no driver was provided for that,
the storage medium will fail to probe and try later from
scratch. Even if we consider that the hardware description shall be
correct, we could still probe the storage device (especially if it
contains the rootfs).
One way to overcome this situation is to consider the layouts as
devices, and leverage the native notifier mechanism. When a new NVMEM
device is registered, we can populate its nvmem-layout child, if any,
and wait for the matching to be done in order to get the cells (the
waiting can be easily done with the NVMEM notifiers). If the layout
driver is compiled as a module, it should automatically be loaded. This
way, there is no strong order to enforce, any NVMEM device creation
or NVMEM layout driver insertion will be observed as a new event which
may lead to the creation of additional cells, without disturbing the
probes with costly (and sometimes endless) deferrals.
In order to achieve that goal we create a new bus for the nvmem-layouts
with minimal logic to match nvmem-layout devices with nvmem-layout
drivers. All this infrastructure code is created in the layouts.c file.

Subject: [PATCH] nvmem: core: Expose cells through sysfs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The binary content of nvmem devices is available to the user so in the
easiest cases, finding the content of a cell is rather easy as it is
just a matter of looking at a known and fixed offset. However, nvmem
layouts have been recently introduced to cope with more advanced
situations, where the offset and size of the cells is not known in
advance or is dynamic. When using layouts, more advanced parsers are
used by the kernel in order to give direct access to the content of each
cell, regardless of its position/size in the underlying
device. Unfortunately, these information are not accessible by users,
unless by fully re-implementing the parser logic in userland.
Let's expose the cells and their content through sysfs to avoid these
situations. Of course the relevant NVMEM sysfs Kconfig option must be
enabled for this support to be available.
Not all nvmem devices expose cells. Indeed, the .bin_attrs attribute
group member will be filled at runtime only when relevant and will
remain empty otherwise. In this case, as the cells attribute group will
be empty, it will not lead to any additional folder/file creation.
Exposed cells are read-only. There is, in practice, everything in the
core to support a write path, but as I don't see any need for that, I
prefer to keep the interface simple (and probably safer). The interface
is documented as being in the "testing" state which means we can later
add a write attribute if though relevant.

Subject: [PATCH] nvmem: stm32: add support for STM32MP25 BSEC to control OTP
data
On STM32MP25, OTP area may be read/written by using BSEC (boot, security
and OTP control). The BSEC internal peripheral is only managed by the
secure world.
The 12 Kbits of OTP (effective) are organized into the following regions:
- lower OTP (OTP0 to OTP127) = 4096 lower OTP bits,
bitwise (1-bit) programmable
- mid OTP (OTP128 to OTP255) = 4096 middle OTP bits,
bulk (32-bit) programmable
- upper OTP (OTP256 to OTP383) = 4096 upper OTP bits,
bulk (32-bit) programmable,
only accessible when BSEC is in closed state.
As HWKEY and ECIES key are only accessible by ROM code;
only 368 OTP words are managed in this driver (OTP0 to OTP267).
This patch adds the STM32MP25 configuration for reading and writing
the OTP data using the OP-TEE BSEC TA services.

Subject: [PATCH] r8152: add USB device driver for config selection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Subclassing the generic USB device driver to override the
default configuration selection regardless of matching interface
drivers.
The r815x family devices expose a vendor specific function which
the r8152 interface driver wants to handle. This is the preferred
device mode. Additionally one or more USB class functions are
usually supported for hosts lacking a vendor specific driver. The
choice is USB configuration based, with one alternate function per
configuration.
Example device with both NCM and ECM alternate cfgs:

A problem with this is that Linux will prefer class functions over
vendor specific functions. Using the above example, Linux defaults
to cfg #2, running the device in a sub-optimal NCM mode.
Previously we've attempted to work around the problem by
blacklisting the devices in the ECM class driver "cdc_ether", and
matching on the ECM class function in the vendor specific interface
driver. The latter has been used to switch back to the vendor
specific configuration when the driver is probed for a class
function.
This workaround has several issues;
- class driver blacklists is additional maintanence cruft in an
unrelated driver
- class driver blacklists prevents users from optionally running
the devices in class mode
- each device needs double match entries in the vendor driver
- the initial probing as a class function slows down device
discovery
Now these issues have become even worse with the introduction of
firmware supporting both NCM and ECM, where NCM ends up as the
default mode in Linux. To use the same workaround, we now have
to blacklist the devices in to two different class drivers and
add yet another match entry to the vendor specific driver.
This patch implements an alternative workaround strategy -
independent of the interface drivers. It avoids adding a
blacklist to the cdc_ncm driver and will let us remove the
existing blacklist from the cdc_ether driver.
As an additional bonus, removing the blacklists allow users to
select one of the other device modes if wanted.

The rtl8152_cfgselector_probe() should set the USB configuration to the
vendor mode only for the devices which the driver (r8152) supports.
Otherwise, no driver would be used for such devices.

Subject: [PATCH] r8152: Rename RTL8152_UNPLUG to RTL8152_INACCESSIBLE
Whenever the RTL8152_UNPLUG is set that just tells the driver that all
accesses will fail and we should just immediately bail. A future patch
will use this same concept at a time when the driver hasn't actually
been unplugged but is about to be reset. Rename the flag in
preparation for the future patch.
This is a no-op change and just a search and replace.

Subject: [PATCH] i915: Move list_count() to list.h as list_count_nodes() for
broader use
Some of the existing users, and definitely will be new ones, want to
count existing nodes in the list. Provide a generic API for that by
moving code from i915 to list.h.

Subject: [PATCH] nvmem: Do not expect fixed layouts to grab a layout driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Two series lived in parallel for some time, which led to this situation:
- The nvmem-layout container is used for dynamic layouts
- We now expect fixed layouts to also use the nvmem-layout container but
this does not require any additional driver, the support is built-in the
nvmem core.
Ensure we don't refuse to probe for wrong reasons.
Fixes: 27f699e578b1 ("nvmem: core: add support for fixed cells *layout*")

Subject: [PATCH] of: device: Export of_device_make_bus_id()
This helper is really handy to create unique device names based on their
device tree path, we may need it outside of the OF core (in the NVMEM
subsystem) so let's export it. As this helper has nothing patform
specific, let's move it to of/device.c instead of of/platform.c so we
can add its prototype to of_device.h.

Subject: [PATCH] nvmem: Move of_nvmem_layout_get_container() in another header
nvmem-consumer.h is included by consumer devices, extracting data from
NVMEM devices whereas nvmem-provider.h is included by devices providing
NVMEM content.
The only users of of_nvmem_layout_get_container() outside of the core
are layout drivers, so better move its prototype to nvmem-provider.h.
While we do so, we also move the kdoc associated with the function to
the header rather than the .c file.

Before adding all the NVMEM layout bus infrastructure to the core, let's
move the main nvmem_device structure in an internal header, only
available to the core. This way all the additional code can be added in
a dedicated file in order to keep the current core file tidy.

This hook is meant to be used by any provider and instantiating a layout
just for this is useless. Let's instead move this hook to the nvmem
device and add it to the config structure to be easily shared by the
providers.
While at moving this hook, rename it ->fixup_dt_cell_info() to clarify
its main intended purpose.

From fc29fd821d9ac2ae3d32a722fac39ce874efb883 Mon Sep 17 00:00:00 2001

Subject: [PATCH] nvmem: core: Rework layouts to become regular devices
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Current layout support was initially written without modules support in
mind. When the requirement for module support rose, the existing base
was improved to adopt modularization support, but kind of a design flaw
was introduced. With the existing implementation, when a storage device
registers into NVMEM, the core tries to hook a layout (if any) and
populates its cells immediately. This means, if the hardware description
expects a layout to be hooked up, but no driver was provided for that,
the storage medium will fail to probe and try later from
scratch. Even if we consider that the hardware description shall be
correct, we could still probe the storage device (especially if it
contains the rootfs).
One way to overcome this situation is to consider the layouts as
devices, and leverage the native notifier mechanism. When a new NVMEM
device is registered, we can populate its nvmem-layout child, if any,
and wait for the matching to be done in order to get the cells (the
waiting can be easily done with the NVMEM notifiers). If the layout
driver is compiled as a module, it should automatically be loaded. This
way, there is no strong order to enforce, any NVMEM device creation
or NVMEM layout driver insertion will be observed as a new event which
may lead to the creation of additional cells, without disturbing the
probes with costly (and sometimes endless) deferrals.
In order to achieve that goal we create a new bus for the nvmem-layouts
with minimal logic to match nvmem-layout devices with nvmem-layout
drivers. All this infrastructure code is created in the layouts.c file.

Subject: [PATCH] nvmem: core: Expose cells through sysfs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The binary content of nvmem devices is available to the user so in the
easiest cases, finding the content of a cell is rather easy as it is
just a matter of looking at a known and fixed offset. However, nvmem
layouts have been recently introduced to cope with more advanced
situations, where the offset and size of the cells is not known in
advance or is dynamic. When using layouts, more advanced parsers are
used by the kernel in order to give direct access to the content of each
cell, regardless of its position/size in the underlying
device. Unfortunately, these information are not accessible by users,
unless by fully re-implementing the parser logic in userland.
Let's expose the cells and their content through sysfs to avoid these
situations. Of course the relevant NVMEM sysfs Kconfig option must be
enabled for this support to be available.
Not all nvmem devices expose cells. Indeed, the .bin_attrs attribute
group member will be filled at runtime only when relevant and will
remain empty otherwise. In this case, as the cells attribute group will
be empty, it will not lead to any additional folder/file creation.
Exposed cells are read-only. There is, in practice, everything in the
core to support a write path, but as I don't see any need for that, I
prefer to keep the interface simple (and probably safer). The interface
is documented as being in the "testing" state which means we can later
add a write attribute if though relevant.

Subject: [PATCH] nvmem: stm32: add support for STM32MP25 BSEC to control OTP
data
On STM32MP25, OTP area may be read/written by using BSEC (boot, security
and OTP control). The BSEC internal peripheral is only managed by the
secure world.
The 12 Kbits of OTP (effective) are organized into the following regions:
- lower OTP (OTP0 to OTP127) = 4096 lower OTP bits,
bitwise (1-bit) programmable
- mid OTP (OTP128 to OTP255) = 4096 middle OTP bits,
bulk (32-bit) programmable
- upper OTP (OTP256 to OTP383) = 4096 upper OTP bits,
bulk (32-bit) programmable,
only accessible when BSEC is in closed state.
As HWKEY and ECIES key are only accessible by ROM code;
only 368 OTP words are managed in this driver (OTP0 to OTP267).
This patch adds the STM32MP25 configuration for reading and writing
the OTP data using the OP-TEE BSEC TA services.
