[PATCH v4 0/3] wireless: p54 devicetree conversion

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

This is an older patch of mine that I lost track of. We already decided
a while ago that the OMAP2 platform should probably be removed entirely,
and this is the only known user, but it's probably a good idea to still
get the driver changes in, in case there are other out-of-tree users.

We probably don't have to worry about bisectability any more though,
so the devicetree and driver changes can just get merged independently
through the OMAP and wireless trees, respectively.

[PATCH v4 1/3 net-next] dt-bindings: net: add st,stlc4560/p54spi binding

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

The SPI version of Prism54 was sold under a couple of different
names and supported by the Linux p54spi driver, but there was
never a DT binding for it.

Document the four known names of this device and the properties
that are sufficient for its use on the Nokia N8x0 tablet.

As I don't have this hardware or documentation for it, this is
purely based on existing usage in the driver.

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

See https://patchwork.kernel.org/project/devicetree/patch/20260430081242.3686993-2-arnd@kernel.org

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.

Thanks for the report, I've fixed it now for v5, to adjust for the
renamed file.

[PATCH v4 2/3 net-next] p54spi: convert to devicetree

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

The Prism54 SPI driver hardcodes GPIO numbers and expects users to
pass them as module parameters, apparently a relic from its life as a
staging driver. This works because there is only one user, the Nokia
N8x0 tablet.

Convert this to the gpio descriptor interface and DT based probing
to improve this and simplify the code at the same time.

v4:
 - make gpio line optional again
 - fix EPROBE_DEFER handling
 - match only st,stlc4560 compatible value, with binding change

 - rebase an older patch
