[PATCH 0/7] RPi touchscreen as a panel driver again

After splitting the panel driver out into a panel and bridge due to
panel review, the feedback from bridge maintainers was that it didn't
make sense as a bridge.  I completely agree with them.  This series
returns the driver to being a panel, but this time probing as an i2c
client rather than a DSI device (due to review from bridge
submission).

Eric Anholt (7):
  drm/bridge: Support hotplugging panel-bridge.
  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.
  dt-bindings: Document the Raspberry Pi Touchscreen nodes.
  drm/panel: Add support for the Raspberry Pi 7" Touchscreen.
  ARM: dts: bcm2835: Enable the Raspberry Pi touchscreen panel.
