Hi Andy,

Thanks for your patches, some remarks inline.

The function name sounds like it would return the current status rather
than enabling them. Better vop2_power_domain_enable_all(). Also a
rk3588_ prefix would be nice.

Please add a rk3588_ prefix to all functions that are rk3588 only.

The vop2_output_if_is_* defines are used only once. Maybe a big:

switch (id) {
case ROCKCHIP_VOP2_EP_HDMI0:
case ROCKCHIP_VOP2_EP_HDMI1:
...
}

would look a bit better overall.

Not sure if this will change with future extensions, but currently
*if_pixclk_div will always be 2 and *if_dclk_div will alway be 4,
so maybe better write it like this

> + *dclk_core_div = dclk_rate / dclk_core_rate;

*dclk_core_div is calculated the same way for all cases. You could pull
this out of the if/else.

if_dclk_rate is unused here.

Both *if_pixclk_div and *if_dclk_div will always be 1.

This function has return type unsigned long. Also this error is never
checked for by the caller.

Replace ';' with ':' in the format string, some whitespaces are missing.

This already lacks an error check, shame on me...
