Updates for v6.7

DP:
- use existing helpers for DPCD handling instead of open-coded functions
- set the subconnector type according to the plugged cable / dongle
  skip validity check for DP CTS EDID checksum

DPU:
- continued migration of feature flags to use core revision checks
- reworked interrupts code to use '0' as NO_IRQ, removed raw IRQ indices
  from log / trace output

gpu:
- a7xx support (a730, a740)
- fixes and additional speedbins for a635, a643

core:
- decouple msm_drv from kms to more cleanly support headless devices (like
  imx5+a2xx)

drm/msm/dsi: free TX buffer in unbind 2023-10-16T14:27:33+00:00 Dmitry Baryshkov dmitry.baryshkov@linaro.org 2023-10-12T01:29:09+00:00 5e05be78264594634860087953649487f486ffcc If the drm/msm init code gets an error during output modeset initialisation, the kernel will report an error regarding DRM memory manager not being clean during shutdown. This is because msm_dsi_modeset_init() allocates a piece of GEM memory for the TX buffer, but destruction of the buffer happens only at msm_dsi_host_destroy(), which is called during DSI driver's remove() time, much later than the DRM MM shutdown. To solve this issue, move the TX buffer destruction to dsi_unbind(), so that the buffer is destructed at the correct time. Note, we also have to store a reference to the address space, because priv->kms->aspace is cleared before components are unbound.
