I'm sorry but I have already commented on v1 that all the mess in here
don't seem necessary. For Reference:

"""
 You trying to bypass the input selection mux. There is no reason to do
 so.

 Your input clocks should be
 * OSC
 * vid_pll
 * fdiv3
 * fdiv4

 While the pwm driver could welcome a rework around how it deal with DT
 and the clocks, this S4 chip does not warrant any change compared to
 previous generation (AFAICT)

 All the stuff around "extern_clk" should go away IMO.

Unless you can *really* justify why this approach is required, it is
firm Nack.
