Subject: [PATCH 00/16] clk: at91: Rework DT bindings
This is the promised rework of the at91 PMC clocks driver. It is mainly
necessary to remove the DTC warnings but it also complies with the CCF
rule that there should be one node per controller instead of one node
per clock.
This only handles the PMC, I'm planning to also rework the SCKC bindings
later (without breaking the DT ABI).
The series is based on top of clk-next plus at91-dt so I don't think it
is convenient to have it this cycle. However, I would really like to
ensure we agree on the new bindings this cycle before converting all the
other platforms as this is a bit tedious.
The first two patches are actually fixes and may be considered for this
cycle.
One nice note:
at91-sama5d2_xplained.dtb goes from 29351 bytes to 22082 bytes
drivers/clk/at91/built-in.o changes that way:
text data bss dec hex
34792 24 732 35548 8adc before
39438 32 741 40211 9d13 after
28300 32 741 29073 7191 without dt-compat
