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.
