[PATCH v12 00/38] ep93xx device tree conversion

[PATCH v12 00/38] ep93xx device tree conversion

[Nikita Shubin via B4 Relay]

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:
  - tristate
  - drop MFD_SYSCON/REGMAP
  - add AUXILIARY_BUS/REGMAP_MMIO
  - prefixed all static with ep9xx_
  - s/clk_hw_register_ddiv()/ep93xx_clk_register_ddiv()/
  - s/clk_register_div()/ep93xx_clk_register_div()/
  - dropped devm_ep93xx_clk_hw_register_fixed_rate_parent_data macro
  - s/devm_ep93xx_clk_hw_register_fixed_rate_parent_data()/devm_clk_hw_register_fixed_rate_parent_data()/

Fixed dtschema compain for cs4270, see deps.

Patches should be formated with '--histogram'

This series depends on:
- clk: fixed-rate: add devm_clk_hw_register_fixed_rate_parent_data()
  (applied to clk-next)
- ASoC: dt-bindings: cirrus,cs4271: Convert to dtschema (applied to
  bronie/sound for-next)

+description: |
+  Central resources are controlled by a set of software-locked registers,
+  which can be used to prevent accidental accesses. Syscon generates
+  the various bus and peripheral clocks and controls the system startup
+  configuration.
+
+  The System Controller (Syscon) provides:
+  - Clock control
+  - Power management
+  - System configuration management
+
+  Syscon registers are common for all EP93xx SoC's, through some actual peripheral
+  may be missing depending on actual SoC model.

Does it mean you still have a few patches without tags?
What are their respective numbers?

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:


doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20240909-ep93xx-v12-20-e86ab2423d4b@maquefel.me

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Hello Rob,

The list of warnings/errors is empty,
so I believe that you have a bug in your bot/scripts.


Kind regards,

Yeah, I think all patches pass test, just something first patch did not
get applied leading to further issues. Including this a bit weird one -
empty warnings.

The file that was claimed to be missing is added in patch #6 of this
series. So I don't think this error is valid.

I've merged the series into the for-next branch of the arm-soc
tree now. The timing isn't great as I was still waiting for
that final Ack, but it seem better to have it done than to keep
respinning the series.

I won't send it with the initial pull requests this week
but hope to send this one once I get beck from LPC, provided
there are no surprises that require a rebase.

Thank you!

This, in particular, will move forward to the GPIO descriptor and
getting rid of old legacy GPIO APIs.
