This binding will be used to define the properties and configuration for the LVDS Controller in DT. Signed-off-by: Dharma Balasubiramani Reviewed-by: Rob Herring --- Changelog v1 -> v2 - Remove '|' in description, as there is no formatting to preserve. - Remove 'gclk' from clock-names as there is only one clock(pclk). - Remove the unused headers and include only used ones. - Change the compatible name specific to SoC (sam9x75) instead of entire series. - Change file name to match the compatible name. --- .../bridge/microchip,sam9x75-lvds.yaml | 55 +++++++++++++++++++ 1 file changed, 55 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/bridge/microchip,sam9x75-lvds.yaml diff --git a/Documentation/devicetree/bindings/display/bridge/microchip,sam9x75-lvds.yaml b/Documentation/devicetree/bindings/display/bridge/microchip,sam9x75-lvds.yaml new file mode 100644 index 000000000000..862ef441ac9f --- /dev/null +++ b/Documentation/devicetree/bindings/display/bridge/microchip,sam9x75-lvds.yaml @@ -0,0 +1,55 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/display/bridge/microchip,sam9x75-lvds.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Microchip SAM9X75 LVDS Controller + +maintainers: + - Dharma Balasubiramani + +description: + The Low Voltage Differential Signaling Controller (LVDSC) manages data + format conversion from the LCD Controller internal DPI bus to OpenLDI + LVDS output signals.
