Signed-off-by: Liu Ying --- v4->v5: * Address Andrzej Hajda's comments. * Get the bs-gpios property instead of the bs[3:0]-gpios properties. * Implement error propagation for panel register configurations. * Other minor changes to improve the code quality. v3->v4: * Move the relevant dt-bindings to a separate patch to address Stefan Wahren's comment. 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. drivers/gpu/drm/panel/Kconfig | 5 + drivers/gpu/drm/panel/Makefile | 1 + drivers/gpu/drm/panel/panel-himax-hx8369a.c | 608 ++++++++++++++++++++++++++++ 3 files changed, 614 insertions(+) create mode 100644 drivers/gpu/drm/panel/panel-himax-hx8369a.c diff --git a/drivers/gpu/drm/panel/Kconfig b/drivers/gpu/drm/panel/Kconfig index 024e98e..81b0bf0 100644 --- a/drivers/gpu/drm/panel/Kconfig +++ b/drivers/gpu/drm/panel/Kconfig @@ -16,6 +16,11 @@ config DRM_PANEL_SIMPLE that it can be automatically turned off when the panel goes into a low power state. +config DRM_PANEL_HIMAX_HX8369A + tristate "Himax HX8369A panel" + depends on OF + select DRM_MIPI_DSI + config DRM_PANEL_LD9040 tristate "LD9040 RGB/SPI panel" depends on OF && SPI diff --git a/drivers/gpu/drm/panel/Makefile b/drivers/gpu/drm/panel/Makefile index 4b2a043..d5dbe06 100644 --- a/drivers/gpu/drm/panel/Makefile +++ b/drivers/gpu/drm/panel/Makefile @@ -1,4 +1,5 @@ obj-$(CONFIG_DRM_PANEL_SIMPLE) += panel-simple.o +obj-$(CONFIG_DRM_PANEL_HIMAX_HX8369A) += panel-himax-hx8369a.o obj-$(CONFIG_DRM_PANEL_LD9040) += panel-ld9040.o obj-$(CONFIG_DRM_PANEL_S6E8AA0) += panel-s6e8aa0.o obj-$(CONFIG_DRM_PANEL_SHARP_LQ101R1SX01) += panel-sharp-lq101r1sx01.o diff --git a/drivers/gpu/drm/panel/panel-himax-hx8369a.c b/drivers/gpu/drm/panel/panel-himax-hx8369a.c new file mode 100644 index 0000000..9e5c34f --- /dev/null +++ b/drivers/gpu/drm/panel/panel-himax-hx8369a.c @@ -0,0 +1,608 @@ +/* + * Himax HX8369A panel driver. + * + * Copyright (C) 2011-2014 Freescale Semiconductor, Inc. + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + * + * This driver is based on Samsung s6e8aa0 panel driver. + */ + +#include +#include +#include + +#include +#include +#include + +#include
