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.

This is needed to prevent copying it into kernel 4.14.
These device tree files are already integrated into kernel 4.14 and we
would like to use the upstream versions only.

The marvell,88e6352 and marvell,88e6172 compatible strings are used in
target/linux/generic/files/drivers/net/phy/mvsw61xx.c. No idea why grep
missed them when I searched for them.
Thanks to Syrone Wong for noticing and reporting my mistake.

Fixes invalid device tree parameters.
Drop the mvsw61xx node used in mvebu device tree source files. It looks
like some kind of ethernet switch cargo cult. Neither the
marvell,88e6352 nor the marvell,88e6172 compatible strings can be found
in any LEDE file or in the kernel sources.

Make the dts file match with what is upstream, to ensure it has the
latest changes and switching to newer kernels is easier.
