drm/: Constify struct drm_driver

2020-11-06T09:31:26Z

Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support. Subsequent patch will address this. - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver. Note that for armada I also went ahead and made the ioctl array const. Only cc'ing the driver people who've not been converted (everyone else is way too much). v2: Fix one misplaced const static, should be static const (0day) v3: - Improve commit message (Sam) Acked-by: Sam Ravnborg Cc: kernel test robot Acked-by: Maxime Ripard Reviewed-by: Alex Deucher Signed-off-by: Daniel Vetter Cc: Sam Ravnborg Cc: Dave Airlie Cc: Gerd Hoffmann Cc: virtualization@lists.linux-foundation.org Cc: Harry Wentland Cc: Leo Li Cc: Alex Deucher Cc: Christian König Cc: Eric Anholt Cc: Maxime Ripard Cc: Ben Skeggs Cc: nouveau@lists.freedesktop.org Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20201104100425.1922351-5-daniel.vetter@ffwll.ch

drm/tiny/repaper: Drop edp->enabled

Same patch as the mipi-dbi one, atomic tracks this for us already, we just have to check the right thing.

drm/cma-helper: Rework DRM_GEM_CMA_VMAP_DRIVER_OPS macro

2020-06-10T07:01:41Z

Rename the macro to DRM_GEM_CMA_DRIVER_OPS_VMAP to align naming with SHMEM helpers and drm_gem_cma_prime_import_sg_table_vmap(). An variant of the macro is provided for drivers that override the default .dumb_create callback. Adapt drivers to the changes. v3: * rename macro to signal implicit vmap on imported buffers v2: * provide DRM_GEM_CMA_DRIVER_OPS_WITH_DUMB_CREATE Signed-off-by: Thomas Zimmermann Reviewed-by: Sam Ravnborg Reviewed-by: Laurent Pinchart Reviewed-by: Emil Velikov Link: https://patchwork.freedesktop.org/patch/msgid/20200605073247.4057-3-tzimmermann@suse.de

drm/repaper: Drop explicit drm_mode_config_cleanup call

2020-03-26T15:08:57Z

Allows us to drop the drm_driver.release callback. This is made possible by a preceeding patch which added a drmm_ cleanup action to drm_mode_config_init(), hence all we need to do to ensure that drm_mode_config_cleanup() is run on final drm_device cleanup is check the new error code for _init(). v2: Explain why this cleanup is possible (Laurent). v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas) I also noticed that I've failed to add the error checking, __must_check caught that.

drm/tiny/repaper: Make driver OF-independent

2020-02-10T01:54:46Z

There is one OF call in the driver that limits its area of use. Replace it to generic device_get_match_data() and get rid of OF dependency. While here, cast SPI driver data to certain enumerator type.
