I cannot believe that I spend quite a lot time in finding this bug.
It seems a pitfall people tend to fall in.

In "int64 = int32 * int32", conversion from 32-bits to 64-bits comes
after the multiplication. So this statement may not work as expected.

The debug base clock can be bypassed from the main PLL to the OSC1 clock.
The bypass register is the staysoc1(0x10) register that is in the clock
manager.

This patch adds the option to get the correct parent for the debug base
clock.

We're removing struct clk from the clk provider API. This code is
calling the consumer APIs to change the parent to a 1 MHz fixed
rate clock for each of the clocks that the driver provides. Move
to using the assigned-clock-parents DT property for this instead.
Because this is an ABI break, detect if the property is missing
and fall back to setting the parent explicitly before the clocks
are registered.

Neither spdif_src nor spdif_pll exists, judging by the vendor kernel in
both cases spdif_pre was meant. This brings the naming in line and
hierachy in line with that of sclk_i2s0.

Also allow sclk_spdif and spdif_frac to change their parents rate as
that the upstream dividers are purely there to feed sclk_spdif

While children of orphan clocks are not carried in the orphan-list itself,
they're nevertheless orphans in their own right as they also don't have an
input-rate available. To ease tracking if a clock is an orphan or has an
orphan in its parent path introduce an orphan field into struct clk and
update it and the fields in child-clocks when a clock gets added or removed
from the orphan-list.

The gates were handled with a common piece of framework that was
registering all gates array, that was not using the CLK_OF_DECLARE logic,
and was not using clock-indices but some private masks that were pretty
much equivalent.

both these issues.
