Last time, you confirmed with the IC designers that we had things right.
What's different this time? Have you, for instance, done more thorough
testing, to show that the logical parent structure this driver outputs
is actually what the hardware is doing?

I think maybe this would qualify as:

Fixes: 3bd14ae9da91 ("clk: rockchip: fix incorrect parent for rk3399's {c,g}pll_aclk_perihp_src")

The above is not exactly a pure regression (we really want both
changes), but apparently it wasn't a complete fix.

Uhh, isn't this patch brand new in v2? I don't think that means
"Changes ... None".
