--- v2: * incorporated rob herring and thierry reviews gpio to gpios, gpio to regulator using fixed regulators and pwm backlight is removed, since it is controlled by dcs commands
v3: * incorporated thierry reviews - Added gpio polarity details for reset-gpios - proper naming conventions and sequence wrt panel datasheet (vddp-supply, iovcc-supply, enable-gpios, reset-gpios, dcdc-en-gpios) --- .../bindings/display/panel/jdi,lt070me05000.txt | 33 ++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/panel/jdi,lt070me05000.txt
