Merge tag 'drm-misc-next-2024-03-28' of https://gitlab.freedesktop.org/drm/misc/kernel into drm-next
Two misc-next in one. drm-misc-next for v6.10-rc1: The deal of a lifetime! You get ALL of the previous drm-misc-next-2024-03-21-1 tag!! But WAIT, there's MORE! Cross-subsystem Changes: - Assorted DT binding updates. Core Changes: - Clarify how optional wait_hpd_asserted is. - Shuffle Kconfig names around. Driver Changes: - Assorted build fixes for panthor, imagination, - Add AUO B120XAN01.0 panels. - Assorted small fixes to panthor, panfrost. drm-misc-next for v6.10: UAPI Changes: - Move some nouveau magic constants to uapi. Cross-subsystem Changes: - Move drm-misc to gitlab and freedesktop hosting. - Add entries for panfrost. Core Changes: - Improve placement for TTM bo's in idle/busy handling. - Improve drm/bridge init ordering. - Add CONFIG_DRM_WERROR, and use W=1 for drm. - Assorted documentation updates. - Make more (drm and driver) headers self-contained and add header guards. - Grab reservation lock in pin/unpin callbacks. - Fix reservation lock handling for vmap. - Add edp and edid panel matching, use it to fix a nearly identical panel. Driver Changes: - Add drm/panthor driver and assorted fixes. - Assorted small fixes to xlnx, panel-edp, tidss, ci, nouveau, panel and bridge drivers. - Add Samsung s6e3fa7, BOE NT116WHM-N44, CMN N116BCA-EA1, CrystalClear CMT430B19N00, Startek KD050HDFIA020-C020A, powertip PH128800T006-ZHC01 panels. - Fix console for omapdrm.

+ description:
+ A u32 value that represents the running time dynamic
+ power coefficient in units of uW/MHz/V^2. The
+ coefficient can either be calculated from power
+ measurements or derived by analysis.
+
+ The dynamic power consumption of the GPU is
+ proportional to the square of the Voltage (V) and
+ the clock frequency (f). The coefficient is used to
+ calculate the dynamic power as below -
+
+ Pdyn = dynamic-power-coefficient * V^2 * f
+
+ where voltage is in V, frequency is in MHz.
