VMARC RK3399Pro SOM is a standard SMARC SOM design with
Rockchip RK3399Pro SoC, which is designed by Vamrs.

Specification:
- Rockchip RK3399Pro
- PMIC: RK809-3
- SD slot, 16GiB eMMC
- 2xUSB-2.0, 1xUSB3.0
- USB-C for power supply
- Ethernet, PCIe
- HDMI, MIPI-DSI/CSI, eDP

Add initial support for VMARC RK3399Pro SOM, this would use
with associated carrier board.

Hi Jagan,

looks good in general, just some small things below:

Is vcc5v0_sys really the topmost regulator getting the outside
power-supply?

vcc_lan / vcc_phy is mostly coming from the vendor bsp in some way
and will be named differently in schematics ... also it should be connected
to the regulator tree.

I think we can live without the additional comments for properties :-)

Thanks for pointing this, I forgot to check the vin supply in carrier
board schematics, yes it is VCC12V_DCIN (with 5V to 24V range) like
rock-pi-4. Will update the same.

Infact bsp named this as vcc_phy, I got the vcc_lan from schematics[1]
page 16. Yes it is using VCCIO_3V3_S0 (SWOUT2 from regulator tree), I
will mark this regulator.

True, I have reused it from rock-pi-4 thought that it would compatible
with old. will remove.
