-Subject: [PATCH 2/4] drm/vc4: Make DSI call into the bridge after the DSI link
- is enabled. bring this patch https://patchwork.kernel.org/patch/10480937/ to
- Linux rpi-4.14.y
-
-This allows panels or bridges that need to send DSI commands during
-pre_enable() to successfully send them. We delay DISP0 (aka the
-actual display) enabling until after pre_enable so that pixels aren't
-streaming before then.
-
-v2: Just clear out the encoder->bridge value to disable the midlayer
- calls (idea by Andrzej Hajda).

-Subject: [PATCH 3/4] drm/vc4: Set up the DSI host at pdev probe time, not
- component bind. bring https://patchwork.kernel.org/patch/9902623/ to Linux
- 4.14.y
-
-We need the following things to happen in sequence:
-
-DSI host creation
-DSI device creation in the panel driver (needs DSI host)
-DSI device attach from panel to host.
-DSI drm_panel_add()
-DSI encoder creation
-DSI encoder's DRM panel/bridge attach
-
-Unless we allow device creation while the host isn't up yet, we need
-to break the -EPROBE_DEFER deadlock between the panel driver looking
-up the host and the host driver looking up the panel. We can do so by
-moving the DSI host creation outside of the component bind loop, and
-the panel/bridge lookup/attach into the component bind process.
