2022-09-20drm/hisilicon: Add depends on MMURandy Dunlap1-0/+1
The Kconfig symbol depended on MMU but was dropped by the commit acad3fe650a5 ("drm/hisilicon: Removed the dependency on the mmu") because it already had as a dependency ARM64 that already selects MMU. But later, commit a0f25a6bb319 ("drm/hisilicon/hibmc: Allow to be built if COMPILE_TEST is enabled") allowed the driver to be built for non-ARM64 when COMPILE_TEST is set but that could lead to unmet direct dependencies and linking errors. Prevent a kconfig warning when MMU is not enabled by making DRM_HISI_HIBMC depend on MMU.

2022-08-03drm/gem: rename struct drm_gem_dma_object.{paddr => dma_addr}Danilo Krummrich1-2/+2
The field paddr of struct drm_gem_dma_object holds a DMA address, which might actually be a physical address. However, depending on the platform, it can also be a bus address or a virtual address managed by an IOMMU. Hence, rename the field to dma_addr, which is more applicable. In order to do this renaming the following coccinelle script was used: ``` @@ struct drm_gem_dma_object *gem; @@ - gem->paddr + gem->dma_addr @@ struct drm_gem_dma_object gem; @@ - gem.paddr + gem.dma_addr @exists@ typedef dma_addr_t; symbol paddr; @@ dma_addr_t paddr; <... - paddr + dma_addr ...> @@ symbol paddr; @@ dma_addr_t - paddr + dma_addr ; ``` This patch is compile-time tested with: ``` make ARCH={x86_64,arm,arm64} allyesconfig make ARCH={x86_64,arm,arm64} drivers/gpu/drm` ``` Acked-by: Sam Ravnborg <sam@ravnborg.org> Suggested-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Danilo Krummrich <dakr@redhat.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20220802000405.949236-5-dakr@redhat.com

But it also prevented the driver to be built on other architectures which is useful to have compile test coverage when doing subsystem wide changes.

Without proper care and an agreement between how DSI hosts and devices drivers register their MIPI-DSI entities and potential components, we can end up in a situation where the drivers can never probe. Most drivers were taking evasive maneuvers to try to workaround this, but not all of them were following the same conventions, resulting in various incompatibilities between DSI hosts and devices. Now that we have a sequence agreed upon and documented, let's convert kirin to it.
