Miller" Errors-To: dri-devel-bounces@lists.freedesktop.org Sender: "dri-devel" Novatek nt36672a is a display driver IC that can drive DSI panel. It is also present in the Tianma video mode panel, which is a FHD+ panel with a resolution of 1080x2246 and 6.18 inches size. It is found in some of the Poco F1 phones. This patch adds the display driver for the IC, with support added for this tianma fhd video mode panel. Signed-off-by: Sumit Semwal Reviewed-by: Rob Herring --- v2: remove ports node, making port@0 directly under panel@0 node. v3: updated to replace port@0 to just 'port'. v5: renamed to novatek,nt36672a, since the binding is for the IC and not the panel. --- .../display/panel/novatek,nt36672a.yaml | 81 +++++++++++++++++++ 1 file changed, 81 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/panel/novatek,nt36672a.yaml -- 2.28.0 _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel diff --git a/Documentation/devicetree/bindings/display/panel/novatek,nt36672a.yaml b/Documentation/devicetree/bindings/display/panel/novatek,nt36672a.yaml new file mode 100644 index 000000000000..7f8d1097bee0 --- /dev/null +++ b/Documentation/devicetree/bindings/display/panel/novatek,nt36672a.yaml @@ -0,0 +1,81 @@ +# SPDX-License-Identifier: GPL-2.0-only OR BSD-2-Clause +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/display/panel/novatek,nt36672a.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Novatek NT36672A based DSI display Panels + +maintainers: + - Sumit Semwal + +description: | + The nt36672a IC from Novatek is a generic DSI Panel IC used to drive dsi + panels. + Right now, support is added only for a Tianma FHD+ LCD display panel with a + resolution of 1080x2246.
