Subject: [PATCH] net: ethernet: mtk_eth_soc: fix resource leak in error path
In mtk_probe(), when mtk_ppe_init() or mtk_eth_offload_init() failed,
mtk_mdio_cleanup() isn't called. Fix it.

Subject: [PATCH] net: ethernet: mtk_eth_soc: fix memory leak in error path
In mtk_ppe_init(), when dmam_alloc_coherent() or devm_kzalloc() failed,
the rhashtable ppe->l2_flows isn't destroyed. Fix it.
In mtk_probe(), when mtk_ppe_init() or mtk_eth_offload_init() or
register_netdev() failed, have the same problem. Fix it.

Subject: [PATCH 094/250] net: ethernet: mtk_eth_soc: always
mtk_get_ib1_pkt_type
entries and bind debugfs files would display wrong data on NETSYS_V2 and
later because instead of using mtk_get_ib1_pkt_type the driver would use
MTK_FOE_IB1_PACKET_TYPE which corresponds to NETSYS_V1(.x) SoCs.
Use mtk_get_ib1_pkt_type so entries and bind records display correctly.

Subject: [PATCH 096/250] net: ethernet: mtk_eth_soc: remove incorrect PLL
configuration
MT7623 GMAC0 attempts to configure the system clocking according to the
required speed in the .mac_config callback for non-SGMII, non-baseX and
non-TRGMII modes.
state->speed setting has never been reliable in the .mac_config
callback - there are cases where this is not the link speed,
particularly via ethtool paths, so this has always been unreliable (as
detailed in phylink's documentation.)
There is the additional issue that mtk_gmac0_rgmii_adjust() will only
be called if state->interface changes, which means it only configures
the system clocking on the very first .mac_config call, which will be
made when the network device is first brought up before any link is
established.
Essentially, this code is incredibly buggy, and probably never worked.
Moreover, checking the in-kernel DT files, it seems no platform makes
use of this code path.
Therefore, let's remove it, and disable interface modes for port 0 that
are not SGMII, 1000base-X, 2500base-X or TRGMII on the MT7623.

Subject: [PATCH 097/250] net: ethernet: mtk_eth_soc: remove mac_pcs_get_state
and modernise
Remove the .mac_pcs_get_state function, since as far as I can tell is
never called - no DT appears to specify an in-band-status management
nor SFP support for this driver.
Removal of this, along with the previous patch to remove the incorrect
clocking configuration, means that the driver becomes non-legacy, so
we can remove the "legacy_pre_march2020" status from this driver.

Subject: [PATCH 104/250] net: ethernet: mtk_eth_soc: convert clock bitmap to
u64
The to-be-added MT7988 SoC adds many new clocks which need to be
controlled by the Ethernet driver, which will result in their total
number exceeding 32.
Prepare by converting clock bitmaps into 64-bit types.

NETSYS_V3 uses 64 bits for each counters while older SoCs are using
48/40 bits for each counter.
Support reading per-flow byte and package counters on NETSYS_V3.

Subject: [PATCH 109/250] net: ethernet: mtk_eth_soc: fix NULL pointer on hw
reset
When a hardware reset is triggered on devices not initializing WED the
calls to mtk_wed_fe_reset and mtk_wed_fe_reset_complete dereference a
pointer on uninitialized stack memory.
Break out of both functions in case a hw_list entry is 0.

Subject: [PATCH 112/250] net: ethernet: mtk_eth_soc: add support for in-SoC
SRAM
MT7981, MT7986 and MT7988 come with in-SoC SRAM dedicated for Ethernet
DMA rings. Support using the SRAM without breaking existing device tree
bindings, ie. only new SoC starting from MT7988 will have the SRAM
declared as additional resource in device tree. For MT7981 and MT7986
an offset on top of the main I/O base is used.

Subject: [PATCH 113/250] net: ethernet: mtk_eth_soc: support 36-bit DMA
addressing on MT7988
Systems having 4 GiB of RAM and more require DMA addressing beyond the
current 32-bit limit. Starting from MT7988 the hardware now supports
36-bit DMA addressing, let's use that new capability in the driver to
avoid running into swiotlb on systems with 4 GiB of RAM or more.

Subject: [PATCH] net: phylink: disable PCS polling over major configuration
While we are performing a major configuration, there is no point having
the PCS polling timer running. Stop it before we begin preparing for
the configuration change, and restart it only once we've successfully
completed the change.

Subject: [PATCH] net: phylink: fix NULL pl->pcs dereference during
phylink_pcs_poll_start
The current link mode of the phylink instance may not require an
attached PCS. However, phylink_major_config() unconditionally
dereferences this potentially NULL pointer when restarting the link poll
timer, which will panic the kernel.
Fix the problem by checking whether a PCS exists in phylink_pcs_poll_start(),
otherwise do nothing. The code prior to the blamed patch also only
looked at pcs->poll within an "if (pcs)" block.
Fixes: bfac8c490d60 ("net: phylink: disable PCS polling over major configuration")

Subject: [PATCH 082/125] net: pcs: lynxi: implement pcs_disable op
When switching from 10GBase-R/5GBase-R/USXGMII to one of the interface
modes provided by mtk-pcs-lynxi we need to make sure to always perform
a full configuration of the PHYA.
Implement pcs_disable op which resets the stored interface mode to
PHY_INTERFACE_MODE_NA to trigger a full reconfiguration once the LynxI
PCS driver had previously been deselected in favor of another PCS
driver such as the to-be-added driver for the USXGMII PCS found in
MT7988.

Subject: [PATCH 096/250] net: ethernet: mtk_eth_soc: remove incorrect PLL
configuration
MT7623 GMAC0 attempts to configure the system clocking according to the
required speed in the .mac_config callback for non-SGMII, non-baseX and
non-TRGMII modes.
state->speed setting has never been reliable in the .mac_config
callback - there are cases where this is not the link speed,
particularly via ethtool paths, so this has always been unreliable (as
detailed in phylink's documentation.)
There is the additional issue that mtk_gmac0_rgmii_adjust() will only
be called if state->interface changes, which means it only configures
the system clocking on the very first .mac_config call, which will be
made when the network device is first brought up before any link is
established.
Essentially, this code is incredibly buggy, and probably never worked.
Moreover, checking the in-kernel DT files, it seems no platform makes
use of this code path.
Therefore, let's remove it, and disable interface modes for port 0 that
are not SGMII, 1000base-X, 2500base-X or TRGMII on the MT7623.

Subject: [PATCH 097/250] net: ethernet: mtk_eth_soc: remove mac_pcs_get_state
and modernise
Remove the .mac_pcs_get_state function, since as far as I can tell is
never called - no DT appears to specify an in-band-status management
nor SFP support for this driver.
Removal of this, along with the previous patch to remove the incorrect
clocking configuration, means that the driver becomes non-legacy, so
we can remove the "legacy_pre_march2020" status from this driver.

From 5d8d05fbf804b4485646d39551ac27452e45afd3 Mon Sep 17 00:00:00 2001
From: Lorenzo Bianconi <lorenzo@kernel.org>
Date: Tue, 25 Jul 2023 01:52:02 +0100
Subject: [PATCH 099/250] net: ethernet: mtk_eth_soc: add version in
mtk_soc_data
Introduce version field in mtk_soc_data data structure in order to
make mtk_eth driver easier to maintain for chipset configuration
codebase. Get rid of MTK_NETSYS_V2 bit in chip capabilities.
This is a preliminary patch to introduce support for MT7988 SoC.

Subject: [PATCH 104/250] net: ethernet: mtk_eth_soc: convert clock bitmap to
u64
The to-be-added MT7988 SoC adds many new clocks which need to be
controlled by the Ethernet driver, which will result in their total
number exceeding 32.
Prepare by converting clock bitmaps into 64-bit types.

Subject: [PATCH 105/250] net: ethernet: mtk_eth_soc: add basic support for
MT7988 SoC
Introduce support for ethernet chip available in MT7988 SoC to
mtk_eth_soc driver. As a first step support only the first GMAC which
is hard-wired to the internal DSA switch having 4 built-in gigabit
Ethernet PHYs.

When a hardware reset is triggered on devices not initializing WED the
calls to mtk_wed_fe_reset and mtk_wed_fe_reset_complete dereference a

Subject: [PATCH 112/250] net: ethernet: mtk_eth_soc: add support for in-SoC
SRAM
MT7981, MT7986 and MT7988 come with in-SoC SRAM dedicated for Ethernet
DMA rings. Support using the SRAM without breaking existing device tree
bindings, ie. only new SoC starting from MT7988 will have the SRAM
declared as additional resource in device tree. For MT7981 and MT7986
an offset on top of the main I/O base is used.

Subject: [PATCH 113/250] net: ethernet: mtk_eth_soc: support 36-bit DMA
addressing on MT7988
Systems having 4 GiB of RAM and more require DMA addressing beyond the
current 32-bit limit. Starting from MT7988 the hardware now supports
36-bit DMA addressing, let's use that new capability in the driver to
avoid running into swiotlb on systems with 4 GiB of RAM or more.

Subject: [PATCH 082/125] net: pcs: lynxi: implement pcs_disable op
When switching from 10GBase-R/5GBase-R/USXGMII to one of the interface
modes provided by mtk-pcs-lynxi we need to make sure to always perform
a full configuration of the PHYA.
Implement pcs_disable op which resets the stored interface mode to
PHY_INTERFACE_MODE_NA to trigger a full reconfiguration once the LynxI
PCS driver had previously been deselected in favor of another PCS
driver such as the to-be-added driver for the USXGMII PCS found in
MT7988.

From 663fa1b7e0cb2c929008482014a70c6625caad75 Mon Sep 17 00:00:00 2001
From: Lorenzo Bianconi <lorenzo@kernel.org>
Date: Tue, 7 Mar 2023 15:55:13 +0000
Subject: [PATCH 1/7] net: ethernet: mtk_eth_soc: add MTK_NETSYS_V1 capability
bit
Introduce MTK_NETSYS_V1 bit in the device capabilities for
MT7621/MT7622/MT7623/MT7628/MT7629 SoCs.
Use !MTK_NETSYS_V1 instead of MTK_NETSYS_V2 in the driver codebase.
This is a preliminary patch to introduce support for MT7988 SoC.

From 663fa1b7e0cb2c929008482014a70c6625caad75 Mon Sep 17 00:00:00 2001
From: Lorenzo Bianconi <lorenzo@kernel.org>
Date: Tue, 7 Mar 2023 15:55:13 +0000
Subject: [PATCH 1/7] net: ethernet: mtk_eth_soc: add MTK_NETSYS_V1 capability
bit
Introduce MTK_NETSYS_V1 bit in the device capabilities for
MT7621/MT7622/MT7623/MT7628/MT7629 SoCs.
Use !MTK_NETSYS_V1 instead of MTK_NETSYS_V2 in the driver codebase.
This is a preliminary patch to introduce support for MT7988 SoC.
