Add basic support for the Kontron 3.5" single board computer featuring a
Mediatek i1200 SoC (MT8395/MT8195).
Signed-off-by: Michael Walle <mwalle at kernel.org>

v3:
- add vsys regulator
- correct the LDO input of the mt6360 regulator
- add missing interrupt-cells
- no underscores in node names
- dropped regulator-compatible everywhere and use the correc node name
instead
- reordered mmc0 properties
- split mmc1 pinctrl properties, add no-mmc
- removed all MTK_DRIVE_8mA
- add i2c0 and i2c1
- add comments for spi and i2c busses
- add firmware-name property for scp (this should probably go into the
base dtsi?!)
- add missing tpm compatible
- renamed thermal zones to something more meaningful
- add correct bias-pull-up to (some) i2c busses
- moved reset handling into the PHY node, also added a compatible string
for the PHY.
Mh, my memory is hazy, but IIRC I run into the same problem which was
discussed on netdev some time ago. That is, the PHY driver cannot be
probed unless it is taken out of reset. Which will only happen if you
probe it. And the workaround/advise was to use the compatible string in
that case, which is unfortunate.
Just wanted to point out, that it is *not* the same as snps,reset-*
because the latter will work just fine without the compatible. I'll
go with the compatible for now.
I did *not* add the vbus to the USB ports, not even on the front port.
That is because of:
dependencies:
connector: [ usb-role-switch ]
and we just have a simple USB3.2 USB-A connector, no dual roles. IMHO
that is a bug in the driver, which should handle the vbus supply as
optional.
v2:
- none
