This moves the bindings over, based a lot on toshiba,tc358768.yaml. Unless there's someone known to be better, I've set the maintainer in the yaml as the first person to submit bindings. Signed-off-by: Douglas Anderson <dianders@xxxxxxxxxxxx> --- Changes in v2: - specification => specifier. - power up => power. - Added back missing suspend-gpios. - data-lanes and lane-polarities are are the right place now. - endpoints don't need to be patternProperties. - Specified more details for data-lanes and lane-polarities. - Added old example back in, fixing bugs in it. - Example i2c bus is just called "i2c", not "i2c1" now. .../bindings/display/bridge/ti,sn65dsi86.txt | 87 ------ .../bindings/display/bridge/ti,sn65dsi86.yaml | 279 ++++++++++++++++++ 2 files changed, 279 insertions(+), 87 deletions(-) delete mode 100644 Documentation/devicetree/bindings/display/bridge/ti,sn65dsi86.txt create mode 100644 Documentation/devicetree/bindings/display/bridge/ti,sn65dsi86.yaml diff --git a/Documentation/devicetree/bindings/display/bridge/ti,sn65dsi86.txt b/Documentation/devicetree/bindings/display/bridge/ti,sn65dsi86.txt deleted file mode 100644 index 8ec4a7f2623a..000000000000 --- a/Documentation/devicetree/bindings/display/bridge/ti,sn65dsi86.txt +++ /dev/null @@ -1,87 +0,0 @@ -SN65DSI86 DSI to eDP bridge chip --------------------------------- - -This is the binding for Texas Instruments SN65DSI86 bridge. -http://www.ti.com/general/docs/lit/getliterature.tsp?genericPartNumber=sn65dsi86&fileType=pdf - -Required properties: -- compatible: Must be "ti,sn65dsi86" -- reg: i2c address of the chip, 0x2d as per datasheet -- enable-gpios: gpio specification for bridge_en pin (active high) - -- vccio-supply: A 1.8V supply that powers up the digital IOs. -- vpll-supply: A 1.8V supply that powers up the displayport PLL. -- vcca-supply: A 1.2V supply that powers up the analog circuits. -- vcc-supply: A 1.2V supply that powers up the digital core. - -Optional properties: -- interrupts-extended: Specifier for the SN65DSI86 interrupt line. - -- gpio-controller: Marks the device has a GPIO controller. -- #gpio-cells : Should be two.
