please name that source clock pclkin_cif as in the TRM.
pclkin_cif is the actual input clock - if I'm reading the TRM correctly and
the inverter is part of the soc or so?

That we currently hide / hardcode the phase-handling should not be part of
our outside connection - which should be stable even if we implement this
later.


Yes, I think I will modify them like this:

GATE(PCLK_ISP1_WRAPPER, "pclkin_isp1_wrapper", "pclkin_cif", CLK_IGNORE_UNUSED,
RK3399_CLKGATE_CON(27), 6, GFLAGS),

Thanks.
