Add C3 PLL controller input clock parameters "fix".
What is "parameters" here? Why you are adding it? Is it missing?
Something is not working?
Yes. The previous submission was lost.
What submission is lost?
Fixes: 0e6be855a96d ("dt-bindings: clock: add Amlogic C3 PLL clock controller")
Why? What bug are you fixing?
The input clock of PLL clock controller need the clock whose fw_name is
called "fix".
Then explain this in commit msg.
Will add this in commit msg.

and that's not an ABI break because?
This is "fixed" clock.
I will modify "fix" to "fixed",in next version.
With "fixed" it is still ABI break, right?
No. The clock named "fixed" was initially implemented in the PLL clock
controller driver, but some registers needed secure zone access,
so we put it in secure zone(BL31) implemented and access it through the
SCMI. but the PLL clock driver need uses this clock, so the "fixed"
clock is input as an input source,
We changed the driver and forgot to change the binding, so we added it here.
Best regards,
Krzysztof
