[PATCH 1/6] dt-bindings: panel: explicitly list SPI CPHA and CPOL
From: Krzysztof Kozlowski <hidden>
Date: 2022-07-21 15:32:27
Also in:
dri-devel, linux-devicetree, linux-iio, linux-spi, lkml, netdev
Subsystem:
drm driver for samsung db7430 panels, drm driver for samsung s6d27a1 panels, drm driver for widechips ws2401 panels, drm drivers, drm drivers and misc gpu patches, drm panel drivers, open firmware and flattened device tree bindings, the rest · Maintainers:
Linus Walleij, Markuss Broks, David Airlie, Simona Vetter, Maarten Lankhorst, Maxime Ripard, Thomas Zimmermann, Neil Armstrong, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
The spi-cpha and spi-cpol properties are device specific and should be accepted only if device really needs them. Explicitly list them in device bindings in preparation of their removal from generic spi-peripheral-props.yaml schema.
