Does this need to be sorted alphabetically?

It would be better to leave a blank line here.

It should be `pinctrl-names = "default";` for pwm, see also [1]

The pinctrl should be placed below the clock.

`status = "okay"` is not needed here.
Also remove extra blank lines.

This line is missing a tab, resulting in an indentation error.

#address-cells/#size-cells should be placed above `status = "disabled";`
I think other nodes also need to change this. (Some for #pwm-cells)

> +			interrupt-names = "sys", "pmc", "msg", "legacy", "err", "msi";

I noticed that the bsp 5.10 kernel said that pcie only has 8 MSI vectors,
[2][3] but in the bsp 6.1 kernel it changed to 32 MSI vectors [4].

The rockchip documentation also says there are only 8 MSI vectors:

[5] Page37 8.8 "RK3528/RK3562/RK3576可分配的MSI或者MSI-X总数是8个"
Translate into English: "The total number of MSI or MSI-X that
can be allocated by RK3528/RK3562/RK3576 is 8"

We noticed this when supporting rk3528, so which one is correct?

s/combphy_pu/combphy

+		combphy_pu: phy at ff750000 {

Please change it to `combphy` like rk3568.

Heiko I know you just merged this, it's a bit offensive but I think
it would be better to drop these patches and fix them further.
Or kever would you like to send a fix patch? Although most of
them are typo issues, it will take a few patches to fix it.
