Merge v6.7-rc3 into drm-next
Thomas Zimermann needs 8d6ef26501 ("drm/ast: Disconnect BMC if physical connector is connected") for further ast work in -next. Minor conflicts in ivpu between 3de6d9597892 ("accel/ivpu: Pass D0i3 residency time to the VPU firmware") and 3f7c0634926d ("accel/ivpu/37xx: Fix hangs related to MMIO reset") changing adjacent lines.
