This series aims to convert ep93xx from platform to full device tree support. The main goal is to receive ACK's to take it via Arnd's arm-soc branch. I've moved to b4, tricking it to consider v0 as v1, so it consider's this version to be v3, this exactly the third version. Link to previous versions: https://lore.kernel.org/all/20230424123522.18302-1-nikita.shubin@xxxxxxxxxxx/ Major changes with clocks: - split all ep93xx clk into two groups: - those who are special to ep93xx (i.e. can't be implemented via standard clk's) and use special swlocked registers - those who can be implemented via devm_clk_hw_register_gate, etc... - moved all clk's that are not used via device tree to SoC driver - dropped init and globals - devm_* everywhere Other notable changes: - added a global spinlock for SoC driver to protect swlocked register's. - moved dts file into cirrus - dropped "dt-bindings: gpio: Add Cirrus EP93xx" as it was taken by Bartosz via gpio subsystem on master v6.5-rc2-89-g3acbd4602b05: make dtbs_check ``` make -j34 -C build-linux ARCH=arm CROSS_COMPILE=armv4t-softfloat-linux-gnueabi- dtbs_check -s arch/arm/boot/dts/cirrus/ep93xx-edb9302.dtb:0:0: /soc/spi@808a0000/codec@0: failed to match any schema with compatible: ['cirrus,cs4271'] /home/maquefel/workshop/ts7250-boot-build/build-linux/arch/arm/boot/dts/cirrus/ep93xx-edb9302.dtb: sound: 'simple-audio-card,convert-sample-format' does not match any of the regexes: '^simple-audio-card,codec(@[0-9a-f]+)?$', '^simple-audio-card,cpu(@[0-9a-f]+)?$', '^simple-audio-card,dai-link(@[0-9a-f]+)?$', '^simple-audio-card,plat(@[0-9a-f]+)?$', 'pinctrl-[0-9]+' From schema: /home/maquefel/workshop/ts7250-boot-build/linux/Documentation/devicetree/bindings/sound/simple-card.yaml ``` cirrus,cs4271 is defined in linux/Documentation/devicetree/bindings/sound/cs4271.txt `make dt_binding_check` shows no issues.
