The goal is to recieve ACKs for all patches in series to merge it via Arnd branch.
It was decided from the very beginning of these series, mostly because
it's a full conversion of platform code to DT and it seemed not
convenient to maintain compatibility with both platform and DT.
Following patches require attention from Stephen Boyd or clk subsystem:
- clk: ep93xx: add DT support for Cirrus EP93xx
It is purely possible to add something like devm_clk_hw_register_fixed_rate_parent_data()
for devm managed version clk_hw_register_fixed_rate_parent_data(), still i would like to
leave for the time after this series if it's all possible.
Couse may be it's better to add something like
devm_clk_hw_register_fixed_rate_index() like it's done for
devm_clk_hw_register_fixed_factor_index().
Changelog for this patch:
- added devm_ep93xx_clk_hw_register_fixed_rate_parent_data() for
devm_ version of clk_hw_register_fixed_rate_parent_data()
- s/devm_clk_hw_register_fixed_rate()/devm_ep93xx_clk_hw_register_fixed_rate_parent_data()/
- replaced all devm_clk_hw_register_fixed_factor() to
devm_clk_hw_register_fixed_factor_parent_hw() or
devm_clk_hw_register_fixed_factor_index()
- s/devm_clk_hw_register_gate()/devm_clk_hw_register_gate_parent_data()
Stephen - it think that's you was aiming for - to get rid of all
functions that are using const char* parent_name directly instead of
clk_hw or clk_parent_data.
Patches should be formated with '--histogram'

- drop flags, they were not used anyway
- add OF ID match table
- process "autorepeat", "debounce-delay-ms", prescale from device tree
- drop platform data usage and it's header
- keymap goes from device tree now on

My bot found new DTB warnings on the .dts files added or changed in this
series.
Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.
If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:
pip3 install dtschema --upgrade
New warnings running 'make CHECK_DTBS=y cirrus/ep93xx-bk3.dtb cirrus/ep93xx-edb9302.dtb cirrus/ep93xx-ts7250.dtb' for 20240715-ep93xx-v11-0-4e924efda795@maquefel.me:

well, this seems to come from the fact is still documented in a .txt file
(Documentation/devicetree/bindings/sound/cs4271.txt), which is not really
the scope of this series. Hope it's OK to ignore it for the series.

Indeed it resides in
Documentation/devicetree/bindings/sound/cs4271.txt.
Can we slip for the series ?
Actually i found this one on mail lists:
https://lore.kernel.org/lkml/20240709184231.125207-1-animeshagarwal28@gmail.com/
Conversion of cs4270.txt, Alexander isn't it almost the same thing as
cs4271 ?
