[backport from linux commit a429c60baefd95ab43a2ce7f25d5b2d7a2e431df]
The IMX8MN platform does not have any video processing unit (VPU), and
indeed in the reference manual (document IMX8MNRM Rev 2, 07/2022) there
is no occurrence of its pll. From an analysis of the code and the RM
itself, I think vpu pll is used instead of m7 alternate pll, probably
for copy and paste of code taken from modules of similar architectures.

driver as well as generic rcar_rst UCLASS_RESET reset driver to the

Currently, SDnH is handled together with SDn. This caused lots of
problems, so we want SDnH as a separate clock. Introduce a dummy SDnH

for now. A later patch then will add the proper functionality.

The original devicetrees for PolarFire SoC messed up & defined the

input for the clock controller node. The msspll is not a fixed
frequency clock and later devicetrees handled this properly. Check the
devicetree & if it is one of the fixed ones, register the msspll.
Otherwise, skip registering it & pass the reference clock directly to

not broken by this change.

Currently the clock driver for PolarFire SoC takes a very naive approach
to the relationship between clocks. It reads the dt to get an input
clock, assumes that that is fixed frequency, reads the "clock-frequency"
property & uses that to set up both the "cfg" and "periph" clocks.
Simplifying for the sake of incremental fixes, the "correct" parentage for
the clocks currently supported in U-Boot is that the "cfg" clocks should
be children of the fixed frequency clock in the dt. The AHB clock is one
of these "cfg" clocks and is the parent of the "periph" clocks.
Instead of passing the clock rate of the fixed-frequency clock to the
"cfg" and "periph" registration functions and the name of the parents,
pass their actual parents & use clk_get_rate() to determine their parents
rates.
The "periph" clocks are purely gate clocks and should not be reading the
AHB clocks registers to determine their rates, as they can simply report
the output of clk_get_rate() on their parent.
