2.27.0
Add support for Seeed Studio's stm32mp157c odyssey board.
Board consists of SoM with stm32mp157c with 4GB eMMC and 512 MB DDR3 RAM
and carrier board with USB and ETH interfaces, SD card connector,
wifi and BT chip AP6236.
In this patch only basic kernel boot is supported and interfacing
SD card and on-board eMMC.

Changes in v5:
- fix schema for board's dts
Changes in v4:
- add seeed,stm32mp157c-odyssey-som in compatible
for carrier board
- fix sdmmc2 interface by changing one of the pins
to use
- change eth phy address to 7
Changes in v3:
- fix compilation on tip of stm32-next
due to change in names for pinctrl
- fix deprecated binding for led node
- fix redundant "okay" statuses
- add phy part number for eth in comment
Changes in v2:
- add new odyssey dts to Makefile

When I sent out the device trees for the lxa-mc1, Alex wanted
all pinctrl nodes to be collected in stm32mp15-pinctrl.dtsi.
@Alex, should this be done here as well?

reset-gpios is missing. I see that the vendor u-boot does it
in board code, but you don't want Linux to depend on this.

Hi,
Sorry for the late answer. Yes it has to be defined in
stm32mp15-pinctrl.dtsi. If at the end there are too much definitions for
the same pins or group of pins, I'll find a smarter way for pin
definition, but currently all pin definitions have to be done in
stm32mp15-pinctrl.dtsi.
cheers
Alex
