[airlied: add two missing Kconfig] drm-misc-next for v5.18: UAPI Changes: - Fix invalid IN_FORMATS blob when plane->format_mod_supported is NULL. Cross-subsystem Changes: - Assorted dt bindings updates. - Fix vga16fb vga checking on x86. - Fix extra semicolon in rwsem.h's _down_write_nest_lock. - Assorted small fixes to agp and fbdev drivers. - Fix oops in creating a udmabuf with 0 pages. - Hot-unplug firmware fb devices on forced removal - Reqquest memory region in simplefb and simpledrm, and don't make the ioresource as busy. Core Changes: - Mock a drm_plane in drm-plane-helper selftest. - Assorted bug fixes to device logging, dbi. - Use DP helper for sink count in mst. - Assorted documentation fixes. - Assorted small fixes. - Move DP headers to drm/dp, and add a drm dp helper module. - Move the buddy allocator from i915 to common drm. - Add simple pci and platform module init macros to remove a lot of boilerplate from some drivers. - Support microsoft extension for HMDs and specialized monitors. - Improve edid parser's deep color handling. - Add type 7 timing support to edid parser. - Add a weak backpointer to the ttm_bo from ttm_resource - Add 3 eDP panels. Driver Changes: - Add support for HDMI and JZ4780 to ingenic. - Add support for higher DP/eDP bitrates to nouveau. - Assorted driver fixes to tilcdc, vmwgfx, sn65dsi83, meson, stm, panfrost, v3d, gma500, vc4, virtio, mgag200, ast, radeon, amdgpu, nouveau, various bridge drivers. - Convert and revert exynos dsi support to bridge driver. - Add vcc supply regulator support for sn65dsi83. - More conversion of bridge/chipone-icn6211 to atomic. - Remove conflicting fb's from stm, and add support for new hw version. - Add device link in parade-ps8640 to fix suspend/resume. - Update Boe-tv110c9m init sequence. - Add wide screen support to AST2600. - Fix omapdrm implicit dma_buf fencing. - Add support for multiple overlay planes to vkms. - Convert bridge/anx7625 to atomic, add HDCP support, add eld support for audio, and fix HPD. - Add driver for ChromeOS privacy screen. - Handover display from firmware to vc4 more gracefully, and support nomodeset. - Add flexible and ycbcr pixel formats to stm/ltdc. - Convert exynos mipi dsi to atomic. - Add initial dual core group GPUs support to panfrost. - No longer add exclusive fence in amdgpu as shared fence. - Add CSC and full range supoprt to vc4. - Shutdown the display on system shutdown and unbind. - Add Multi-Inno Technology MI0700S4T-6 simple panel.

Request memory regions in all drivers

-------------------------------------

Go through all drivers and add code to request the memory regions that the

driver uses. This requires adding calls to request_mem_region(),

pci_request_region() or similar functions. Use helpers for managed cleanup
|

DRM and fbdev drivers. Still, it's the correct thing to do.
