drm/tinydrm: Fix fbdev pixel format

2019-04-11T14:16:06+00:00

Due to copy/paste error, the fbdev format was changed to 32bpp = XRGB8888 which is an emulated format for the RGB565 drivers. Revert to to using the fallback which is dev->mode_config.preferred_depth for the drivers that set it or 32bpp for those that don't (repaper, st7586).

drm/tinydrm: Use drm_dev_enter/exit()

2019-03-04T14:32:21+00:00

This protects device resources from use after device removal. There are 3 ways for driver-device unbinding to happen: - The driver module is unloaded causing the driver to be unregistered. This can't happen as long as there are open file handles because a reference is taken on the module. - The device is removed (Device Tree overlay unloading). This can happen at any time. - The driver sysfs unbind file can be used to unbind the driver from the device. This can happen any time. v2: Since drm_atomic_helper_shutdown() has to be called after drm_dev_unplug() we don't want do block ->disable after unplug.

drm/tinydrm: do not reply on drmP.h from drm_gem_cma_helper.h

2019-01-09T21:48:56+00:00

drmP.h was the only header file in the past and a lot of files rely on that drmP.h defines everything. The goal is to one day to delete drmP.h and as a step towards this it will no longer be included in the headers files in include/drm/ To prepare tinydrm/ for this add dependencies that othwewise was pulled in by drmP.h from drm_gem_cma_helper.h To avoid that tinydrm.h became "include everything", push include files to the individual drivers.
