* drm/panel: Add support for Truly NT35597 panel driverAbhinav Kumar2018-10-251-0/+7
| | | | | | | | | | | | | | | | | Add support for Truly NT35597 panel driver used in MSM reference platforms. This panel driver supports both single DSI and dual DSI modes. However, this patch series adds support only for dual DSI mode.

* drm/panel: rm68200: Add backlight dependencyArnd Bergmann2018-03-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Like many other panel drivers, this one fails to build when backlight support is disabled: drivers/gpu/drm/panel/panel-raydium-rm68200.o: In function `rm68200_probe': panel-raydium-rm68200.c:(.text+0x14a): undefined reference to `devm_of_find_backlight' This adds the appropriate dependency. Note that while include/linux/backlight.h provides a stub inline when backlight support is not enabled, this isn't enough to deal with the case where backlight support is built as a module but the panel driver is built-in, in which case linking will still fail as above. One way to avoid this is to add a dependency such as this: depends on BACKLIGHT_CLASS_DEVICE || BACKLIGHT_CLASS_DEVICE=n but that is rather complex and misses the point that the panel support is mostly useless without backlight support.

| | | | | | | | | | | | | | | | | | The ARM reference designs "Versatile AB" and "Versatile PB" contain panel connectors with autodetection of the connected panel type. This adds a small driver utilizing the MFD syscon look-up to read the autodetection register and set up the corresponding panel appropriately.

* 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.
