* drm/panel: simple: Support delays in panel functionsAjay Kumar2014-08-061-0/+30
| | | | | | | | | For most of the panels, we need to provide delays during various stages of panel power up and power down. Add a structure to hold those delay values and use them in corresponding functions. Signed-off-by: Ajay Kumar <ajaykumar.rs@samsung.com> Signed-off-by: Thierry Reding <treding@nvidia.com>

* drm/panel: simple: Remove simple-panel compatibleThierry Reding2014-08-061-2/+0
| | | | | | | | | | simple-panel is not a valid panel model, so there is no data (video timings, etc.) associated with it. Therefore drivers can't do anything useful with it, so it should not appear in the table of OF matches. Device trees will always need to specify the exact model of the panel.

* drm/panel: make DRM_PANEL_LD9040 depend on SPIRussell King2014-07-141-2/+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>
* drm/panel: consolidate unnecessary explicit dependenciesRussell King2014-07-141-3/+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.

* drm: Add panel supportThierry Reding2013-12-171-0/+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.
