Dear DRM maintainers,

The script ./scripts/checkkconfigsymbols.py warns on invalid references to
Kconfig symbols (often, minor typos, name confusions or outdated references).

This patch series addresses all issues reported by ./scripts/checkkconfigsymbols.py
in ./drivers/gpu/ for Kconfig and Makefile files. Issues in the Kconfig and
Makefile files indicate some shortcomings in the overall build definitions, and
often are true actionable issues to address.

These issues can be identified and filtered by:

  ./scripts/checkkconfigsymbols.py | grep -E "drivers/gpu/.*(Kconfig|Makefile)" -B 1 -A 1

After applying this patch series on linux-next (next-20210817), the command
above yields just one further issues to address:

DRM_AMD_DC_DCE11_0
Referencing files: drivers/gpu/drm/amd/display/dc/dce100/Makefile

  Conclusion: No action required.
  Rationale:
    drivers/gpu/drm/amd/display/dc/dce100/Makefile refers to
    DRM_AMD_DC_DCE11_0 in a comment, after an "ifdef 0".


Please pick this patch series into your drm-next tree.

Best regards,

Lukas

commit 1f0f01515172 ("drm/rockchip: Add support for Rockchip Soc RGB
output interface") accidently adds to select the non-existing config
DRM_RGB in ./drivers/gpu/drm/rockchip/Kconfig.

Luckily, ./scripts/checkkconfigsymbols.py warns on non-existing configs:

DRM_RGB
Referencing files: drivers/gpu/drm/rockchip/Kconfig

So, remove the reference to the non-existing config DRM_RGB.

Commit 04ed8459f334 ("drm/amdgpu: remove chash") removes the chash
architecture and its corresponding config CHASH.

There is still a reference to CHASH in the config DRM_AMDGPU in
./drivers/gpu/drm/Kconfig.

Remove this obsolete reference to config CHASH.

Commit 57692c94dcbe ("drm/v3d: Introduce a new DRM driver for Broadcom V3D
V3.x+") adds the config DRM_V3D, which depends on "ARCH_BCMSTB".

Although, a bit confusing: all Broadcom architectures in
./arch/arm/mach-bcm/Kconfig have the prefix "ARCH_BCM", except for
ARCH_BRCMSTB, i.e., the config for Broadcom BCM7XXX based boards.

So, correct the reference ARCH_BCMSTB to the intended ARCH_BRCMSTB.

Commit 89d4f98ae90d ("ARM: remove zte zx platform") removes the config
ARCH_ZX. So, since then, the DRM Support for ZTE SoCs (config DRM_ZTE)
depends on this removed config ARCH_ZX and cannot be selected.

Fortunately, ./scripts/checkkconfigsymbols.py detects this and warns:

ARCH_ZX
Referencing files: drivers/gpu/drm/zte/Kconfig

So, remove this obsolete DRM support.

Commit 55b68fb856b5 ("drm/omap: squash omapdrm sub-modules into one")
removes the config OMAP2_DSS in ./drivers/gpu/drm/omapdrm/dss/Kconfig,
while moving the other configs into./drivers/gpu/drm/omapdrm/Kconfig, but
misses to remove an obsolete selection of OMAP2_DSS in config DRM_OMAP.

Hence, ./scripts/checkkconfigsymbols.py warns:

OMAP2_DSS
Referencing files: drivers/gpu/drm/omapdrm/Kconfig

Remove this reference in an obsolete selection.
