Merge tag 'drm-misc-next-2020-06-19' of git://anongit.freedesktop.org/drm/drm-misc into drm-next
drm-misc-next for v5.9: UAPI Changes: - Add DRM_MODE_TYPE_USERDEF for video modes specified in cmdline. Cross-subsystem Changes: - Assorted devicetree binding updates. - Add might_sleep() to dma_fence_wait(). - Fix fbdev's get_user_pages_fast() handling, and use pin_user_pages. - Small cleanup with IS_BUILTIN in video/fbdev drivers. - Fix video/hdmi coding style for infoframe size. Core Changes: - Silence vblank output during init. - Fix DP-MST corruption during send msg timeout. - Clear leak in drm_gem_objecs_lookup(). - Make newlines work with force connector attribute. - Fix module refcounting error in drm_encoder_slave, and use new i2c api. - Header fix for drm_managed.c - More struct_mutex removal for !legacy drivers: - Remove gem_free_object() - Removal of drm_gem_object_put_unlocked(). - Show current->comm alongside pid in debug printfs. - Add drm_client_modeset_check() + drm_client_framebuffer_flush(). - Replace drm_fb_swab16 with drm_fb_swap that also supports 32-bits. - Remove mode->vrefresh, and compactify drm_display_mode. - Use drm_* macros for logging and warnings. - Add WARN when drm_gem_get_pages is used on a private obj. - Handle importing and imported dmabuf better in shmem helpers. - Small fix for drm/mm hole size comparison, and remove invalid entry optimization. - Add a drm/mm selftest. - Set DSI connector type for DSI panels. - Assorted small fixes and documentation updates. - Fix DDI I2C device registration for MST ports, and flushing on destroy. - Fix master_set return type, used by vmwgfx. - Make the drm_set/drop_master ioctl symmetrical. Driver Changes: Allow iommu in the sun4i driver and use it for sun8i. - Simplify backlight lookup for omap, amba-clcd and tilcdc. - Hold reg_lock for rockchip. - Add support for bridge gpio and lane reordering + polarity to ti-sn65dsi86, and fix clock choice. - Small assorted fixes to tilcdc, vc4, i915, omap, fbdev/sm712fb, fbdev/pxafb, console/newport_con, msm, virtio, udl, malidp, hdlcd, bridge/ti-sn65dsi86, panfrost. - Remove hw cursor support for mgag200, and use simple kms helper + shmem helpers. - Add support for KOE Allow iommu in the sun4i driver and use it for sun8i. - Simplify backlight lookup for omap, amba-clcd and tilcdc. - Hold reg_lock for rockchip. - Add support for bridge gpio and lane reordering + polarity to ti-sn65dsi86, and fix clock choice. - Small assorted fixes to tilcdc, vc4 (multiple), i915. - Remove hw cursor support for mgag200, and use simple kms helper + shmem helpers. - Add support for KOE TX26D202VM0BWA panel. - Use GEM CMA functions in arc, arm, atmel-hlcdc, fsi-dcu, hisilicon, imx, ingenic, komeda, malidp, mcde, meson, msxfb, rcar-du, shmobile, stm, sti, tilcdc, tve200, zte. - Remove gem_print_info. - Improve gem_create_object_helper so udl can use shmem helpers. - Convert vc4 dt bindings to schemas, and add clock properties. - Device initialization cleanups for mgag200. - Add a workaround to fix DP-MST short pulses handling on broken hardware in i915. - Allow build test compiling arm drivers. - Use managed pci functions in mgag200 and ast. - Use dev_groups in malidp. - Add per pixel alpha support for PX30 VOP in rockchip. - Silence deferred probe logs in panfrost.
