Signed-off-by: Liu Ying --- v6->v7: * None. v5->v6: * None. v4->v5: * Merge the bs[3:0]-gpios properties into one property - bs-gpios. This addresses Andrzej Hajda's comment. v3->v4: * Newly introduced in v4. This is separated from the relevant driver patch in v3 to address Stefan Wahren's comment. .../devicetree/bindings/panel/himax,hx8369a.txt | 39 ++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 Documentation/devicetree/bindings/panel/himax,hx8369a.txt diff --git a/Documentation/devicetree/bindings/panel/himax,hx8369a.txt b/Documentation/devicetree/bindings/panel/himax,hx8369a.txt new file mode 100644 index 0000000..3a44b70 --- /dev/null +++ b/Documentation/devicetree/bindings/panel/himax,hx8369a.txt @@ -0,0 +1,39 @@ +Himax HX8369A WVGA 16.7M color TFT single chip driver with internal GRAM + +Himax HX8369A is a WVGA resolution driving controller. +It is designed to provide a single chip solution that combines a source +driver and power supply circuits to drive a TFT dot matrix LCD with +480RGBx864 dots at the maximum. + +The HX8369A supports several interface modes, including MPU MIPI DBI Type +A/B mode, MIPI DPI/DBI Type C mode, MIPI DSI video mode, MIPI DSI command +mode and MDDI mode.
