[PATCH 0/8] RPi touchscreen panel driver v4

[Eric Anholt]

The review for v3 was basically "no, the panel should probe first so
that we have the connector by the time KMS is done initializing."  To
do this, I needed to be able to register the custom (non-OF-generated)
DSI device without the host being present (patch 6).  Also check out
patch 4 for a new cleanup to panel-bridge.

Eric Anholt (8):
  drm/vc4: Fix DSI T_INIT timing.
  drm/vc4: Fix misleading name of the continuous flag.
  drm/vc4: Use drm_mode_vrefresh() in DSI fixup, in case vrefresh is 0.
  drm/bridge: Add a devm_ allocator for panel bridge.
  drm/vc4: Delay DSI host registration until the panel has probed.
  drm: Allow DSI devices to be registered before the host registers.
  dt-bindings: Document the Raspberry Pi Touchscreen nodes.
  drm/panel: Add support for the Raspberry Pi 7" Touchscreen.
