Hi Junhao,

This should probably be added where the rest of rk3568 dtb is located,
not with the rk3588 ones.

Thanks for your reminder, I made a mistake in the order when renaming dts, I will fix it

nit: Please be consistent where comments is added, for recgulators above
the comments is above the node, suggest you move the comment above the
"&gmac0 {" line, and same for similar comments.

I will edit it. This looks better:

&gmac0 {
	status = "disabled";
};

The snps,reset props is deprecated use resets props in phy node instad.

I edited it and it works fine, is the following correct to write?

Can be dropped, already in base dtsi.

max-frequency is not in sdhci node of rk356x.dtsi and rk3568.dtsi.
I simply removed the max-frequency and it worked fine.
Can it really be removed?

Thanks for your review, I will fix all problems in next version!
