2018-10-25drm/stm: Use drm_fbdev_generic_setup()Noralf Trønnes1-9/+2
The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing. drm_fbdev_generic_setup() handles mode_config.num_connector being zero. In that case it retries fbdev setup on the next .output_poll_changed.

Add mode_valid() function to filter modes according to available pll clock values and "preferred" modes. It is particularly useful for hdmi modes that require precise pixel clocks. Note that "preferred" modes are always accepted: - this is important for panels because panel clock tolerances are bigger than hdmi ones and there is no reason to not accept them (the fps may vary a little but it is not a problem). - the hdmi preferred mode will be accepted too, but userland will be able to use others hdmi "valid" modes if necessary.

2017-06-30drm: Convert atomic drivers from CRTC .disable() to .atomic_disable()Laurent Pinchart1-2/+3
The CRTC .disable() helper operation is deprecated for atomic drivers, the new .atomic_disable() helper operation being preferred. Convert all atomic drivers to .atomic_disable() to avoid cargo-cult use of .disable() in new drivers.

2017-06-30drm: Add old state pointer to CRTC .enable() helper functionLaurent Pinchart1-2/+3
The old state is useful for drivers that need to perform operations at enable time that depend on the transition between the old and new states. While at it, rename the operation to .atomic_enable() to be consistent with .atomic_disable(), as the .enable() operation is used by atomic helpers only.
