Merge tag 'drm-next-2024-07-18' of https://gitlab.freedesktop.org/drm/kernel
Pull drm updates from Dave Airlie: "There's a lot of stuff in here, amd, i915 and xe have new platform work, lots of core rework around EDID handling, some new COMPILE_TEST options, maintainer changes and a lots of other stuff. Summary: core: - deprecate DRM data and return 0 date - connector: Create a set of helpers to help with HDMI support - Remove driver owner assignments - Allow more drivers to compile with COMPILE_TEST - Conversions to drm_edid - Sprinkle MODULE_DESCRIPTIONS everywhere they are missing - Remove drm_mm_replace_node - print: Add a drm prefix to warn level messages too, remove ___drm_dbg, consolidate prefix handling - New monochrome TV mode variant ttm: - improve number of page faults on some platforms - fix test builds under PREEMPT_RT - more test coverage ci: - Require a more recent version of mesa - improve farm setup and test generation dma-buf: - warn if reserving 0 fence slots - internal API heap enhancements fbdev: - Create memory manager optimized fbdev emulation panic: - Allow to select fonts - improve drm_fb_dma_get_scanout_buffer - Allow to dump kmsg to the screen bridge: - Remove redundant checks on bridge->encoder - Remove drm_bridge_chain_mode_fixup - bridge-connector: Plumb in the new HDMI helper - analogix_dp: Various improvements, handle AUX transfers timeout - samsung-dsim: Fix timings calculation - tc358767: Plenty of small fixes, fix no connector attach, fix clocks - sii902x: state validation improvements panels: - Switch panels from register table initialization to proper code - Now that the panel code tracks the panel state, remove every ad-hoc implementation in the panel drivers - More cleanup of prepare / enable state tracking in drivers - edp: Drop legacy panel compatibles - simple-bridge: Switch to devm_drm_bridge_add - New panels: Lincoln Tech Sol LCD185-101CT, Microtips Technology 13-101HIEBCAF0-C, Microtips Technology MF-103HIEB0GA0, BOE nv110wum-l60, IVO t109nw41, WL-355608-A8, PrimeView PM070WL4, Lincoln Technologies LCD197, Ortustech COM35H3P70ULC, AUO G104STN01, K&d kd101ne3-40ti amdgpu: -
