Hello,
This small series adds initial support for the DRM bridges to NVIDIA Tegra
DRM driver. This is required by newer device-trees where we model the LVDS
encoder bridge properly.
Changelog:
v4: - Following review comments that were made by Laurent Pinchart to the v3,
we now create and use the "bridge connector".
v3: - Following recommendation from Sam Ravnborg, the new bridge attachment
model is now being used, i.e. we ask bridge to *not* create a connector
using the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag.
- The bridge is now created only for the RGB (LVDS) output, and only
when necessary. For now we don't need bridges for HDMI or DSI outputs.
- I noticed that we're leaking OF node in the panel's error code path,
this is fixed now by the new patch "Don't leak OF node on error".
v2: - Added the new "rgb: Don't register connector if bridge is used"
patch, which hides the unused connector provided by the Tegra DRM
driver when bridge is used, since bridge provides its own connector
to us.
- Please notice that the first "Support DRM bridges" patch was previously
sent out as a standalone v1 change.
