One LVDS port receives even pixels, and the other receives odd pixels. Optionally, a backlight and an enable GPIO can be specified as properties. Migrate 'auo,g133han01', 'auo,g185han01', 'auo,g190ean01', 'koe,tx26d202vm0bwa' and 'nlt,nl192108ac18-02d' over to the new file. The objectives with one file for all the simple LVDS panels with dual ports are: - Make it simpler to add bindings for this kind of LVDS panels - Keep the number of bindings file lower - Keep the binding documentation for this kind of LVDS panels more consistent - Make it possible for drivers to get pixel order via drm_of_lvds_get_dual_link_pixel_order(), as the optional 'ports' property is allowed Suggested-by: Sam Ravnborg Cc: Thierry Reding Cc: Sam Ravnborg Cc: David Airlie Cc: Daniel Vetter Cc: Rob Herring Cc: Lucas Stach Cc: Sebastian Reichel Signed-off-by: Liu Ying --- .../panel/panel-simple-lvds-dual-ports.yaml | 85 ++++++++++++++++++++++ .../bindings/display/panel/panel-simple.yaml | 10 --- 2 files changed, 85 insertions(+), 10 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/panel/panel-simple-lvds-dual-ports.yaml diff --git a/Documentation/devicetree/bindings/display/panel/panel-simple-lvds-dual-ports.yaml b/Documentation/devicetree/bindings/display/panel/panel-simple-lvds-dual-ports.yaml new file mode 100644 index 00000000..4608481 --- /dev/null +++ b/Documentation/devicetree/bindings/display/panel/panel-simple-lvds-dual-ports.yaml @@ -0,0 +1,85 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/display/panel/panel-simple-lvds-dual-ports.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Simple LVDS panels with one power supply and dual LVDS ports + +maintainers: + - Liu Ying + - Thierry Reding + - Sam Ravnborg + +description: | + This binding file is a collection of the LVDS panels that + has dual LVDS ports and requires only a single power-supply. + One LVDS port receives even pixels, and the other receives odd pixels. + There are optionally a backlight and an enable GPIO. + The panel may use an OF graph binding for the association to the display, + or it may be a direct child node of the display. + + If the panel is more advanced a dedicated binding file is required. + +allOf: + - $ref: panel-common.yaml# + +properties: + + compatible: + enum: + # compatible must be listed in alphabetical order, ordered by compatible. + # The description in the comment is mandatory for each compatible. + + # AU Optronics Corporation 13.3" FHD (1920x1080) TFT LCD panel + - auo,g133han01 + # AU Optronics Corporation 18.5" FHD (1920x1080) TFT LCD panel + - auo,g185han01 + # AU Optronics Corporation 19.0" (1280x1024) TFT LCD panel + - auo,g190ean01 + # Kaohsiung Opto-Electronics Inc. 10.1" WUXGA (1920 x 1200) LVDS TFT LCD panel + - koe,tx26d202vm0bwa + # NLT Technologies, Ltd. 15.6" FHD (1920x1080) LVDS TFT LCD panel + - nlt,nl192108ac18-02d + + backlight: true + enable-gpios: true + port: true + ports: true + power-supply: true + +additionalProperties: false + +required: + - compatible + - power-supply + +examples: + - | + panel: panel-lvds { + compatible = "koe,tx26d202vm0bwa"; + power-supply = <&vdd_lcd_reg>; + + ports { + #address-cells = <1>; + #size-cells = <0>; + + port@0 { + dual-lvds-even-pixels; + reg = <0>; + + panel_lvds0_in: endpoint { + remote-endpoint = <&lvds0_out>; + }; + }; + + port@1 { + dual-lvds-odd-pixels; + reg = <1>; + + panel_lvds1_in: endpoint { + remote-endpoint = <&lvds1_out>; + }; + }; + }; + }; diff --git a/Documentation/devicetree/bindings/display/panel/panel-simple.yaml b/Documentation/devicetree/bindings/display/panel/panel-simple.yaml index f9750b0..62618e4 100644 --- a/Documentation/devicetree/bindings/display/panel/panel-simple.yaml +++ b/Documentation/devicetree/bindings/display/panel/panel-simple.yaml @@ -57,14 +57,8 @@ properties: - auo,g104sn02 # AU Optronics Corporation 12.1" (1280x800) TFT LCD panel - auo,g121ean01 - # AU Optronics Corporation 13.3" FHD (1920x1080) TFT LCD panel - - auo,g133han01 # AU Optronics Corporation 15.6" (1366x768) TFT LCD panel - auo,g156xtn01 - # AU Optronics Corporation 18.5" FHD (1920x1080) TFT LCD panel - - auo,g185han01 - # AU Optronics Corporation 19.0" (1280x1024) TFT LCD panel - - auo,g190ean01 # AU Optronics Corporation 31.5" FHD (1920x1080) TFT LCD panel - auo,p320hvn03 # AU Optronics Corporation 21.5" FHD (1920x1080) color TFT LCD panel @@ -167,8 +161,6 @@ properties: - kingdisplay,kd116n21-30nv-a010 # Kaohsiung Opto-Electronics Inc. 5.7" QVGA (320 x 240) TFT LCD panel - koe,tx14d24vm1bpa - # Kaohsiung Opto-Electronics Inc. 10.1" WUXGA (1920 x 1200) LVDS TFT LCD panel - - koe,tx26d202vm0bwa # Kaohsiung Opto-Electronics.
