[PATCH/RFC 0/6] dt-bindings: display: Convert DWC HDMI TX bindings to YAML

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

This patch series attempts a conversion of the DWC HDMI TX DT bindings
to YAML. I've marked it as RFC as the base schema doesn't work is
intended in this (naive) approach, and I'm not sure how to fix it
properly.

The DWC HDMI TX is an HDMI transmitter IP core from Synopsys, integrated
in various SoCs with different glue layers. As such, some properties are
defined in a common document, but sometimes need to be overridden by
platform-specific bindings.

Patch 1/6 adds a base schema for the common properties, based on the
existing dw_hdmi.txt document. Patches 2/6 to 4/6 then convert the
platformspecific bindings for Renesas, NXP and Rockchip SoCs. Patch 5/6
replaces the reference to dw_hdmi.txt in the Allwinner bindings with a
reference to the YAML base schema, and patch 6/6 drops dw_hdmi.txt.

My attempts at defining properties in the base schema, including it in
the platform-specific schema with an allOf: $ref..., and overridding
properties didn't work, as DT schemas don't define properties in a way
that can be overridden, but instead define validation rules that are all
considered. Both the rules in the base schema and in the
platform-specific schemas are evaluated.

One possible way around this would be to not pull in the whole base
schema, but specific rules. This is however a bit cumbersome to use in
my opinion. Is there a better way to achieve this ?

I have volunteered Philipp Zabel and Mark Yao as maintainers for the
i.MX6 and Rockchip bindings respectively. Please let me know if you
would prefer a different maintainer, or ack the respective patch if this
is fine with you.
