Thus I take this as an Acked-by: And I have committed to drm-misc-next Sam
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.

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 <sam@ravnborg.org> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Rob Herring <robh@kernel.org> Cc: Maxime Ripard <mripard@kernel.org> Cc: Yannick Fertre <yannick.fertre@st.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: dri-devel@lists.freedesktop.org Cc: devicetree@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
