2014-07-22drm/panel: simple: add support for InnoLux N156BGE-L21 panelAlban Bedel1-0/+25
This panel is used by the Medcom Wide and supported by the simple-panel driver. Signed-off-by: Alban Bedel <alban.bedel@avionic-design.de> Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-07-22drm/panel: s6e8aa0: Use static inline for upcastingThierry Reding1-1/+4
Use a static inline function for upcasting a struct drm_panel to the driver-specific structure. The advantage over using a macro is that it gives us additional type checking. Acked-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-07-22drm/dsi: Use peripheral's channel for DCS commandsThierry Reding1-2/+2
When executing DCS commands, use the channel associated with the DSI peripheral rather than one explicitly specified in the function call. Devices shouldn't be able to step on each others' toes like this. Acked-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-07-22drm/dsi: Make mipi_dsi_dcs_write() return ssize_tThierry Reding1-2/+2
This function returns the value of the struct mipi_dsi_host_ops' .transfer() so make sure the return types are consistent. Acked-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-07-15drm/panel: add support for Foxlink FL500WVR00-A0T panelBoris BREZILLON1-0/+25

2014-07-14drm/panel: Set non-continuous clock flag on supporting panelsAlexandre Courbot1-2/+3
The LG LD070WX3-SL01 and Panasonic VVX10F004B00 are DSI support non-continuous clock mode. Set the MIPI_DSI_CLOCK_NON_CONTINUOUS to their definition so host drivers become aware of this capability.

2014-07-14drm/panel: make DRM_PANEL_LD9040 depend on SPIRussell King1-2/+1
Rather than DRM_PANEL_LD9040 selecting SPI, which then results in an increase in the probability of Kconf reporting circular dependencies (we're one "select" away from that right now), make this depend on SPI instead. This is akin to having some driver select DRM. Having some drivers depend on a subsystem, and other drivers select a subsystem is a recipe for circular dependencies, and there's really no need for it. The potential circular dependency (which can be caused today by the addition of selecting DRM_PANEL from DRM_IMX_LDB) is: symbol DMADEVICES is selected by SAMSUNG_DMADEV symbol SAMSUNG_DMADEV is selected by S3C64XX_PL080 symbol S3C64XX_PL080 is selected by SPI_S3C64XX symbol SPI_S3C64XX depends on SPI symbol SPI is selected by DRM_PANEL_LD9040 symbol DRM_PANEL_LD9040 depends on DRM_PANEL symbol DRM_PANEL is selected by DRM_IMX_LDB symbol DRM_IMX_LDB depends on MFD_SYSCON symbol MFD_SYSCON is selected by POWER_RESET_KEYSTONE symbol POWER_RESET_KEYSTONE depends on POWER_SUPPLY symbol POWER_SUPPLY is selected by HID_SONY symbol HID_SONY depends on NEW_LEDS symbol NEW_LEDS is selected by BACKLIGHT_ADP8860 symbol BACKLIGHT_ADP8860 depends on BACKLIGHT_CLASS_DEVICE symbol BACKLIGHT_CLASS_DEVICE is selected by FB_MX3 symbol FB_MX3 depends on MX3_IPU symbol MX3_IPU depends on DMADEVICES Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-07-14drm/panel: consolidate unnecessary explicit dependenciesRussell King1-3/+1
DRM_PANEL_LD9040 and DRM_PANEL_S6E8AA0 both explicitly depended on DRM_PANEL && DRM, whereas DRM_PANEL_SIMPLE relies upon the dependency on the menu. We do not need to use explicit dependencies if we make the menu depend on DRM_PANEL && DRM - this will implicitly make each entry in the menu depend on DRM_PANEL && DRM without this needing to be explicitly stated against every entry.

2014-04-04drm/panel: simple: Allow DSI panels to provide mode flagsThierry Reding1-0/+3
In order to differentiate between the different video modes (burst vs. non-burst, sync pulses vs. sync events) supported by peripherals, pass the flags that specify this mode in the panel description to the DSI peripheral device when probed. Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-04-04drm/panel: simple: Allow GPIO accesses to sleepThierry Reding1-2/+2
The enable GPIO for panels may be provided by GPIO expanders on slow busses (such as I2C), and therefore toggling the GPIO may sleep. Since these accesses don't happen in interrupt context, use the *_cansleep() variants of the GPIO API. Signed-off-by: Thierry Reding <treding@nvidia.com>

2013-12-17drm/panel: Add simple panel supportThierry Reding3-0/+432
Add a driver for simple panels. Such panels can have a regulator that provides the supply voltage and a separate GPIO to enable the panel. Optionally the panels can have a backlight associated with them so it can be enabled or disabled according to the panel's power management mode. Support is added for two panels: An AU Optronics 10.1" WSVGA and a Chunghwa Picture Tubes 10.1" WXGA panel. Signed-off-by: Thierry Reding <treding@nvidia.com>
2013-12-17drm: Add panel supportThierry Reding1-0/+5
Add a very simple framework to register and lookup panels. Panel drivers can initialize a DRM panel and register it with the framework, allowing them to be retrieved and used by display drivers. Currently only support for DPMS and obtaining panel modes is provided. However it should be sufficient to enable a large number of panels. The framework should also be easily extensible to support more sophisticated kinds of panels such as DSI. The framework hasn't been tied into the DRM core, even though it should be easily possible to do so if that's what we want. In the current implementation, display drivers can simple make use of it to retrieve a panel, obtain its modes and control its DPMS mode. Note that this is currently only tested on systems that boot from a device tree. No glue code has been written yet for systems that use platform data, but it should be easy to add.
