Merge tag 'drm-misc-next-2020-12-17' of git://anongit.freedesktop.org/drm/drm-misc into drm-next
drm-misc-next for v5.12: UAPI Changes: - Not necessarily one, but we document that userspace needs to force probe connectors. Cross-subsystem Changes: - Require FB_ATY_CT for aty on sparc64. - video: Fix documentation, and a few compiler warnings. - Add devicetree bindings for DP connectors. - dma-buf: Update kernel-doc, and add might_lock for resv objects in begin/end_cpu_access. Core Changes: - ttm: Warn when releasing a pinned bo. - ttm: Cleanup bo size handling. - cma-helper: Remove prime infix, and implement mmap as GEM CMA functions. - Split drm_prime_sg_to_page_addr_arrays into 2 functions. - Add a new api to install irq using devm. - Update panel kerneldoc to inline style. - Add DP support to drm/bridge. - Assorted small fixes to ttm, fb-helper, scheduler. - Add atomic_commit_setup function callback. - Automatically use the atomic gamma_set, instead of forcing drivers to declare the default atomic version. - Allow using degamma for legacy gamma if gamma is not available. - Clarify that primary/cursor planes are not tied to 1 crtc (depending on possible_crtcs). - ttm: Cleanup the lru handler. Driver Changes: - Add pm support to ingenic. - Assorted small fixes in radeon, via, rockchip, omap2fb, kmb, gma500, nouveau, virtio, hisilicon, ingenic, s6e63m0 panel, ast, udlfb. - Add BOE NV110WTM-N61, ys57pss36bh5gq, Khadas TS050 panels. - Stop using pages with drm_prime_sg_to_page_addr_arrays, and switch all callers to use ttm_sg_tt_init. - Cleanup compiler and docbook warnings in a lot of fbdev devices. - Use the drmm_vram_helper in hisilicon. - Add support for BCM2711 DSI1 in vc4. - Add support for 8-bit delta RGB panels to ingenic. - Add documentation on how to test vkms. - Convert vc4 to atomic helpers. - Use degamma instead of gamma table in omap, to add support for CTM and color encoding/range properties. - Rework omap DSI code, and merge all omapdrm modules now that the last omap panel is now a drm panel. - More refactoring of omap dsi code. - Enable 10/12 bpc outputs in vc4.
