[linux-sunxi] [PATCH v6 3/6] drm: sun4i: dsi: Add bridge support
Some display panels would come up with a non-DSI output, those
can have an option to connect the DSI host by means of interface
bridge converter.
This DSI to non-DSI interface bridge converter would require
DSI Host to handle drm bridge functionalities in order to
communicate interface bridge.
This patch adds support for bridge functionalities in Allwinner
DSI controller.
Supporting down-stream bridge makes few changes in the driver.
- It drops drm_connector and related operations as drm_bridge_attach
creates connector during attachment.
- It drop panel pointer and iterate the bridge, so-that it can operate
the normal bridge and panel_bridge in constitutive callbacks.
- It uses devm_drm_of_get_bridge for panel or bridge lookup. It uses
port 0 and endpoint 0 to support I2C-based bridges eventhough the
usual Allwinner DSI OF graph doesn't require this for panel and
non-I2C based downstream bridges.

[linux-sunxi] [PATCH v6 2/6] drm: sun4i: dsi: Add component only once DSI device attached
Having component_add for running all drm bind callbacks returns
error or unbound due to chain of DSI devices connected across
bridge topology on a display pipeline.
In a typical bridge oriented display pipeline where the host is
connected to the bridge converter and that indeed connected to
a panel.
DRM => SUN6I DSI Host => Chipone ICN6211 => BananaPi Panel
The bridge converter is looking for a panel to probe first and
then attach the host. The host attach is looking for a bridge
converter to probe and preserve bridge pointer, at this movement
the host is trying to bind the all callbacks and one of the bind
callback in the DSI host is trying to find the bridge using the
bridge pointer in sun6i_dsi_attach call.

sun6i_dsi_probe().done
However, the movement when panel defers the probe, will make the
bridge converter defer the host attach call which eventually found
a NULL bridge pointer during DSI component bind callback.
So, in order to prevent this scenario of binding invalid bridge,
wait for DSI devices on the pipeline to probe first and start the
binding process by moving component_add in host probe to attach call.

[linux-sunxi] [PATCH v6 1/6] drm: sun4i: dsi: Drop DRM bind race with bridge attach
Existing host driver will keep looking for DRM pointer in
sun6i_dsi_attach and defers even if the particular DSI device
is found for the first time. Meanwhile it triggers the bind
callback and gets the DRM pointer and then continues the
sun6i_dsi_attach.
This makes a deadlock situation if sun6i_dsi_attach is trying
to find the bridge.
If interface bridge is trying to call host attach, then host
sun6i_dsi_attach is trying to find bridge and defers the
interface bridge even if it found the bridge as bind callback
does not complete at the movement. So, this sun6i_dsi_attach
defers interface bridge and triggers the bind callback and
tries to attach the bridge with a bridge pointer which is not
available at the moment.
Eventually these callbacks are triggered recursively, as
sun6i_dsi_attach defers interface bridge and bind callback
defers sun6i_dsi_attach due to invalid bridge ponter.
This patch prevents this situation by probing all DSI devices
on the pipeline first and then triggers the bind callback by
dropping exing DRM binding logic.
