Re: [PATCH v2 1/2] dt-bindings: one binding file for all simple panels
Hi Jyri, Rob, Paul, Miquel. Following patch is now applied to drm-misc-next. Please add your simple panels to this file so we avoid independent bindings files for ecah panel. I will handle the inevitable conflicts when I apply.

[PATCH v2 1/2] dt-bindings: one binding file for all simple panels
There is an increasing number of new simple panels. Common for many of these simple panels are that they have one mandatory power-supply and some of them have backlight and / or an enable gpio. The binding file to describe these panels adds overhead that really do not add value. The binding are known and there is nothing gained from a dedicated binding file nor for any dedicated example. The following patch introduces a single panel-simple.yaml and converts two ampire bindings over to the new file. The conversion - if applied will have following effects: - The maintainer for the individual file will change There is no need for many different maintainers for a simple binding. We have the same situation with the panel-simple driver in the kernel. - The license will change to (GPL-2.0-only OR BSD-2-Clause) There is usually only a single line copied from the original file, a line that is often copied from a datasheet. This license change should be acceptable considered what little is copied. If the license change is not OK we can use a dedicated binding file in these cases. This is a follow-up on Rob's big patch converting a lot of panel bindings to individual files: "dt-bindings: display: Convert a bunch of panels to DT schema" https://patchwork.ozlabs.org/patch/1197683/ The objectives with one file for the relevant simple panels are: - Make it simpler to add bindings for simple panels - Keep the number of bindings file lower and thus easier to find a relevant file to copy from when adding new panels. - Keep the binding documentation for simple panels more consistent - Make it simpler to add support for new panels v2: - spelling fixes (imirkin via irc, Rob) - updated description (Rob) - list properires in alphabetical order - added power-supply to example (Rob) - updated title - reworded changelog a little Signed-off-by: Sam Ravnborg Cc: Thierry Reding Cc: Rob Herring Cc: Maxime Ripard Cc: Yannick Fertre Cc: Mark Rutland Cc: Daniel Vetter Cc: dri-devel@lists.freedesktop.org Cc: devicet...@vger.kernel.org --- .../panel/ampire,am-480272h3tmqw-t01h.yaml| 42 - .../panel/ampire,am800480r3tmqwa1h.txt| 7 --- .../bindings/display/panel/panel-simple.yaml | 59 +++ 3 files changed, 59 insertions(+), 49 deletions(-) delete mode 100644 Documentation/devicetree/bindings/display/panel/ampire,am-480272h3tmqw-t01h.yaml delete mode 100644 Documentation/devicetree/bindings/display/panel/ampire,am800480r3tmqwa1h.txt create mode 100644 Documentation/devicetree/bindings/display/panel/panel-simple.yaml diff --git a/Documentation/devicetree/bindings/display/panel/ampire,am-480272h3tmqw-t01h.yaml b/Documentation/devicetree/bindings/display/panel/ampire,am-480272h3tmqw-t01h.yaml deleted file mode 100644 index c6e33e7f36d0.. --- a/Documentation/devicetree/bindings/display/panel/ampire,am-480272h3tmqw-t01h.yaml +++ /dev/null @@ -1,42 +0,0 @@ -# SPDX-License-Identifier: GPL-2.0 -%YAML 1.2 -$id: http://devicetree.org/schemas/display/panel/ampire,am-480272h3tmqw-t01h.yaml# -$schema: http://devicetree.org/meta-schemas/core.yaml# - -title: Ampire AM-480272H3TMQW-T01H 4.3" WQVGA TFT LCD panel - -maintainers: - - Yannick Fertre - - Thierry Reding - -allOf: - - $ref: panel-common.yaml# - -properties: - compatible: -const: ampire,am-480272h3tmqw-t01h - - power-supply: true - enable-gpios: true - backlight: true - port: true - -required: - - compatible - -additionalProperties: false - -examples: - - | -panel_rgb: panel { - compatible = "ampire,am-480272h3tmqw-t01h"; - enable-gpios = <&gpioa 8 1>; - port { -panel_in_rgb: endpoint { - remote-endpoint = <&controller_out_rgb>; -}; - }; -}; - -... diff --git a/Documentation/devicetree/bindings/display/panel/ampire,am800480r3tmqwa1h.txt b/Documentation/devicetree/bindings/display/panel/ampire,am800480r3tmqwa1h.txt deleted file mode 100644 index 83e2cae1cc1b.. --- a/Documentation/devicetree/bindings/display/panel/ampire,am800480r3tmqwa1h.txt +++ /dev/null @@ -1,7 +0,0 @@ -Ampire AM-800480R3TMQW-A1H 7.0" WVGA TFT LCD panel - -Required properties: -- compatible: should be "ampire,am800480r3tmqwa1h" - -This binding is compatible with the simple-panel binding, which is specified -in simple-panel.txt in this directory. diff --git a/Documentation/devicetree/bindings/display/panel/panel-simple.yaml b/Documentation/devicetree/bindings/display/panel/panel-simple.yaml new file mode 100644 index ..51ca50201182 --- /dev/null +++ b/Documentation/devicetree/bindings/display/panel/panel-simple.yaml @@ -0,0 +1,59 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/display/panel/panel-simple.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Simple panels with one power supply + +maintainers: + - Thierry Re
