The CLK125 output pin at the ethernet PHY is connected via capacitor to
GND and nowhere else. Disable it. Also tune the LED masks.
The MPP56 and MPP60 pins at the SoC are conected to the μPD720202 USB3.0
chip:
- MPP56: wired to PCIe CLKREQ# (out)
- MPP60: wired to PCIe RESET# (in)
Configure the pcie pinmux for these pins.

Make some cosmetic changes in the Buffalo LinkStation LS421DE NAS:
- Delete pointless #xxx-cells
- bootargs: replace earlyprintk with earlycon and remove unneeded args.
- Separate pinmux nodes with empty lines.

The thermal zones kernel documentation is misleading, we cannot use more
than one sensor in a thermal zone node.
Furthermore the drivetemp driver for some reason it only catches one
sensor from the hard drives array (the first available).
In the Buffalo Linkstation LS421DE board there is also a sensor at the
ethernet phy chip that can also be monitored. Very useful to stop the fan
when there are no hard drives in the bays.
(It might be also possible to add the CPU sensor, but it requires kernel
patching for registering the sensor via device tree, using the function:
devm_thermal_zone_of_sensor_register)
Fix the thermal zones to use only one sensor per node and add the ethernet
phy sensor. Also adjust the hdd temperatures to be more conservative for
a mechanical hard drive.

The Buffalo Linkstation LS421DE comes with a Ricoh RS5C372A real time
clock. This RTC has the INTRA pin connected to the power management
circuit, allowing to wake up the device from the power off state when an
alarm is scheduled.
Add the "wakeup-source" property in the RTC dts node to allow the use
of the alarm.
Example of use, the device is powered off and it comes to life after 5
minutes:
echo $(expr $(date '+%s') + 60 * 5) > /sys/class/rtc/rtc0/wakealarm
poweroff
This feature isn't available in the stock firmware.

The Buffalo Linkstation LS421DE isn't able to enable the Level 2 cache
(AKA Aurora cache). As of result of this, the throughput is about half of
the expected, e.g when doing network data transfers.
Fix it by adding the broken-idle property in the coherency fabric node.

Compile the Linkstation poweroff module for the Buffalo LS421DE.
Without this driver the device remains forever halted if a power off
command is executed.
The driver will also allow to use the WoL feature, which wasn't availabe
in the stock firmware.

The Buffalo Linkstation LS421DE has a chassis fan for cooling two internal
hard drives. Currently there is no control over this fan, running always
at fixed medium speed.
With the recent jump to the kernel 5.4, now we can monitor the hard drive
temperature and control the fan with thermal zones.
Install the kmod-hwmon-drivetemp module and wire up a thermal zone on the
dts file to allow automatic fan control by the kernel.
Tested succesfully using a single Crucial BX500 SSD drive.

- Delete useless HDD presence inputs: they aren't buttons, and probably
they are outputs in the stock firmware.
- Change the Function Button keycode: the current one isn't mapped by
the kernel module.
- Use the recommended property names for the ethernet stuff.
- Add missing i2c pinmux.
- Minor cosmetic changes.

The DTS files in files-4.19 and files-5.4 are exactly identical
except for one file (armada-3720-uDPU.dts), which is only present
for 4.19, as it has been upstreamed before 5.4.
Since there is no point in maintaining all these identical files
twice, this patch moves them to the "files" directory, only keeping
the named exception to files-4.19.
