Merge tag 'drm-misc-next-2024-05-30' of https://gitlab.freedesktop.org/drm/misc/kernel into drm-next

drm-misc-next for 6.11:

UAPI Changes:
  - Deprecate DRM date and return a 0 date in DRM_IOCTL_VERSION

Core Changes:
  - connector: Create a set of helpers to help with HDMI support
  - fbdev: Create memory manager optimized fbdev emulation
  - panic: Allow to select fonts, improve drm_fb_dma_get_scanout_buffer

Driver Changes:
  - Remove driver owner assignments
  - Allow more drivers to compile with COMPILE_TEST
  - Conversions to drm_edid
  - ivpu: hardware scheduler support, profiling support, improvements
    to the platform support layer
  - mgag200: general reworks and improvements
  - nouveau: Add NVreg_RegistryDwords command line option
  - rockchip: Conversion to the hdmi helpers
  - sun4i: Conversion to the hdmi helpers
  - vc4: Conversion to the hdmi helpers
  - v3d: Perf counters improvements
  - zynqmp: IRQ and debugfs improvements
  - bridge:
    - Remove redundant checks on bridge->encoder
  - 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
    - New panels: Lincoln Tech Sol LCD185-101CT, Microtips Technology
      13-101HIEBCAF0-C, Microtips Technology MF-103HIEB0GA0, BOE
