2021-02-23drm/gem: Move drm_gem_fb_prepare_fb() to GEM atomic helpersThomas Zimmermann1-2/+2
The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting, but currently located next to framebuffer helpers. Move it to GEM atomic helpers, rename it slightly and adopt the drivers. Same for the rsp simple-pipe helper. Compile-tested with x86-64, aarch64 and arm. The patch is fairly large, but there are no functional changes. v3: * remove out-comented line in drm_gem_framebuffer_helper.h (Maxime) v2: * rename to drm_gem_plane_helper_prepare_fb() (Daniel) * add tutorial-style documentation Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Maxime Ripard <mripard@kernel.org> Link: https://patchwork.freedesktop.org/patch/msgid/20210222141756.7864-1-tzimmermann@suse.de

2021-02-10drm/aspeed: Use dt matching for default register valuesJoel Stanley3-21/+55
There are minor differences in the values for the threshold value and the scan line size between families of ASPEED SoC. Additionally the SCU registers for the output control and scratch registers differ between families. This adds device tree matching to parameterise these values, allowing us to add support for the AST2400 now, and in the future the AST2600.

2021-02-10drm/aspeed: Look up syscon by phandleJoel Stanley1-3/+7
This scales better to multiple families of SoC. The lookup by compatible can be removed in a future change. The fallback path is for the ast2500 platform only. Other platforms will be added with the new style, so they won't need fallback paths.

2020-11-06drm/<drivers>: Constify struct drm_driverDaniel Vetter1-1/+1
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 <sam@ravnborg.org> Cc: kernel test robot <lkp@intel.com> Acked-by: Maxime Ripard <mripard@kernel.org> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Dave Airlie <airlied@redhat.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: virtualization@lists.linux-foundation.org Cc: Harry Wentland <harry.wentland@amd.com> Cc: Leo Li <sunpeng.li@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Christian König <christian.koenig@amd.com> Cc: Eric Anholt <eric@anholt.net> Cc: Maxime Ripard <mripard@kernel.org> Cc: Ben Skeggs <bskeggs@redhat.com> Cc: nouveau@lists.freedesktop.org Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201104100425.1922351-5-daniel.vetter@ffwll.ch
