[PATCH 3/3] arm64: dts: rockchip: add dts for Ariaboard Photonicat RK3568

Hi Junhao,

This should be 'rk3568-photonicat.dts',
e.g. "Radxa ROCK 3A" -> rk3568-rock-3a.dts

> ...

The official model name does not include 'RK3568'.

Maybe these can be moved to rk356x.dtsi?

No need.

There is no vcc5v0_sys, but vcc_syson.

vcc_syson (5v) -> vcc3v3_sys
vcc_sysin (5v) - (mcu) -> vcc_syson
vccin_5v -> vcc_sysin

It's a little weird, but that's what they're calling it.
Also: VCCIN_5V -> VCC5V0_USB30_OTG0

Are you sure this regulator is 5v?

Also you need to enable the clk:

		clocks = <&pmucru CLK_RTC_32K>;
		clock-names = "ext_clock";
		pinctrl-names = "default";
		pinctrl-0 = <&wifi_reg_on_h &clk32k_out1>;

phy-supply = <&vcc3v3_pi6c>;

These are actually pcie30x1m0_pins.

Maybe these can be moved to rk356x.dtsi?

Missing mmc-hs200-1_8v;

Why does sdcard need cap-mmc-highspeed?

> +	max-frequency = <150000000>;
> +	sd-uhs-sdr104;

The sdcard does not have 1.8v io voltage,
so this is wrong, please add no-1-8-v;

sdio wifi does not need disable-wp.

ath10k does not need compatible.

Missing clock-names = "lpo";
