Subject: [PATCH v2] dt-bindings: trivial-devices: Document spi-cpha and spi-cpol
Date: Fri, 30 Aug 2024 14:18:49 -0300	[thread overview]
Message-ID: <20240830171849.3750165-1-festevam@gmail.com> (raw)

There may be cases where a trivial-device needs to describe
the SPI clock polarity and phase via spi-cpol and spi-cpha
properties.

Document these properties to fix the following dt-schema warnings:

rv1108-elgin-r1.dtb: display@0: 'spi-cpha', 'spi-cpol' do not match any of the regexes: 'pinctrl-[0-9]+'

Signed-off-by: Fabio Estevam <festevam@gmail.com>

Changes since v1:
- Add spi-cpha and spi-cpol to trivial-devices.yaml. (Conor)
