From 66e3377c7c81a04b9461254300d9c8ae853eab99 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Wed, 8 Apr 2020 21:50:40 +0200 Subject: [PATCH] dt-bindings: display: convert ilitek,ili9322 to DT Schema The .txt binding explains: " The following optional properties only apply to RGB and YUV input modes and can be omitted for BT.656 input modes: " This constraint is not implmented in the DT Schema. The original binding from the .txt file referenced properties that is included in panel-timing.yaml. The properties in question are: - pixelclk-active - de-active - hsync-active - vsync-active These properties was dropped in the conversion as they are not relevant. v2: - drop properties from panel-timing (Linus) - drop use of spi-slave.yaml (Maxime) - introduce unevaluatedProperties (Maxime) - dropped unused properties (Linus) - delete stray spaces Signed-off-by: Sam Ravnborg Reviewed-by: Linus Walleij Reviewed-by: Rob Herring Cc: Linus Walleij Cc: Thierry Reding Cc: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20200408195109.32692-8-sam@ravnborg.org --- .../bindings/display/panel/ilitek,ili9322.txt | 49 --------------- .../bindings/display/panel/ilitek,ili9322.yaml | 71 ++++++++++++++++++++++ 2 files changed, 71 insertions(+), 49 deletions(-) delete mode 100644 Documentation/devicetree/bindings/display/panel/ilitek,ili9322.txt create mode 100644 Documentation/devicetree/bindings/display/panel/ilitek,ili9322.yaml diff --git a/Documentation/devicetree/bindings/display/panel/ilitek,ili9322.txt b/Documentation/devicetree/bindings/display/panel/ilitek,ili9322.txt deleted file mode 100644 index 3d5ce6a..0000000 --- a/Documentation/devicetree/bindings/display/panel/ilitek,ili9322.txt +++ /dev/null @@ -1,49 +0,0 @@ -Ilitek ILI9322 TFT panel driver with SPI control bus - -This is a driver for 320x240 TFT panels, accepting a variety of input -streams that get adapted and scaled to the panel.
