Signed-off-by: Liu Ying --- v2->v3: * Sort the included header files alphabetically. v1->v2: * Address almost all comments from Thierry Reding. * Remove several DT properties as they can be implied by the compatible string. * Add the HIMAX/himax prefixes to the driver's Kconfig name and driver name. * Move the driver's Makefile entry place to sort the entries alphabetically. * Reuse several standard DCS functions instead of inventing wheels. * Move the panel resetting and power logics to the driver probe/remove stages. This may simplify panel prepare/unprepare hooks. The power consumption should not change a lot at DPMS since the panel enters sleep mode at that time. * Add the module author. * Other minor changes, such as coding style issues. .../devicetree/bindings/panel/himax,hx8369a.txt | 41 ++ drivers/gpu/drm/panel/Kconfig | 5 + drivers/gpu/drm/panel/Makefile | 1 + drivers/gpu/drm/panel/panel-himax-hx8369a.c | 573 +++++++++++++++++++++ 4 files changed, 620 insertions(+) create mode 100644 Documentation/devicetree/bindings/panel/himax,hx8369a.txt create mode 100644 drivers/gpu/drm/panel/panel-himax-hx8369a.c diff --git a/Documentation/devicetree/bindings/panel/himax,hx8369a.txt b/Documentation/devicetree/bindings/panel/himax,hx8369a.txt new file mode 100644 index 0000000..36a2f11 --- /dev/null +++ b/Documentation/devicetree/bindings/panel/himax,hx8369a.txt @@ -0,0 +1,41 @@ +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.
