drm: shmobile: Use backlight helper

2022-06-24T19:45:28+00:00

This started with work on the removal of backlight_properties'
deprecated fb_blank field, much of which can be taken care of by using
helper functions provided by backlight.h instead of directly accessing
fields in backlight_properties. This patch series doesn't involve
fb_blank, but it still seems useful to use helper functions where
appropriate.

Instead of retrieving the backlight brightness in struct
backlight_properties manually, and then checking whether the backlight
should be on at all, use backlight_get_brightness() which does all
this and insulates this from future changes.

drm: Drop drm_framebuffer.h from drm_crtc.h

2022-06-20T20:53:55+00:00

drm_crtc.h has no need for drm_frambuffer.h, so don't include it.
Avoids useless rebuilds of the entire universe when
touching drm_framebuffer.h.

Quite a few placs do currently depend on drm_framebuffer.h without
actually including it directly. All of those need to be fixed
up.

v2: Fix up msm some more
v2: Deal with ingenic and shmobile as well

drm/shmobile: Use drm_module_platform_driver() to register the driver

2022-01-27T18:15:47+00:00

The macro calls to a DRM specific platform driver init handler that checks
whether the driver is allowed to be registered or not.

drm: Remove CONFIG_DRM_KMS_CMA_HELPER option

2021-11-30T10:10:03+00:00

Link drm_fb_cma_helper.o into drm_cma_helper.ko if CONFIG_DRM_KMS_HELPER
has been set. Remove CONFIG_DRM_KMS_CMA_HELPER config option. Selecting
KMS helpers and CMA will now automatically enable CMA KMS helpers.

Some drivers' Kconfig files did not correctly select KMS or CMA helpers.
Fix this as part of the change.

drm/shmobile: Convert to Linux IRQ interfaces

2021-07-25T09:01:12+00:00

Drop the DRM IRQ midlayer in favor of Linux IRQ interfaces. DRM's
IRQ helpers are mostly useful for UMS drivers. Modern KMS drivers
don't benefit from using it.

v3:
	* return error if (ret < 0) (Geert)
	* remove duplicate error message (Geert)
v2:
	* handle errors in platform_get_irq() (Geert, Sergei)
	* store IRQ number in struct shmob_drm_device (Laurent)

drm/: Constify struct drm_driver

2020-11-06T09:31:26+00:00

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)

drm/shmobile: Use GEM CMA object functions

2020-06-10T07:05:12+00:00

Create GEM objects with drm_gem_cma_create_object_default_funcs(), which
allocates the object and sets CMA's default object functions. Corresponding
callbacks in struct drm_driver are cleared. No functional changes are made.

Driver and object-function instances use the same callback functions, with
the exception of vunmap. The implementation of vunmap is empty and left out
in CMA's default object functions.
