[PATCH v3 02/13] drm/tyr: select required dependencies in Kconfig

[Deborah Brouwer]

From: Boris Brezillon <boris.brezillon@xxxxxxxxxxxxx>

Tyr depends on DRM_GPUVM, RUST_DRM_GEM_SHMEM_HELPER, MMU, IOMMU_SUPPORT,
and IOMMU_IO_PGTABLE_LPAE. Select or depend on these symbols in Kconfig so
the required infrastructure is enabled when Tyr is built.

Introduce DRM_TYR_STATIC_DEPS to keep the built-in DRM dependencies
selected even when Tyr is built as a module.
