[PATCH 0/4] media: sunxi: MIPI CSI-2 controllers link fixups

[Paul Kocialkowski <paul.kocialkowski@bootlin.com>]

Fix the MIPI CSI-2 drivers to correctly check enabled links and to
register their subdev even without a sensor attached. This allows
their parent driver to register in that situation and makes it
possible to use a parallel sensor when both parallel and MIPI CSI-2
are fed to the same controller but no sensor is connected to the
MIPI CSI-2 bridge.

With this change, it becomes possible to always describe the links
between the CSI and MIPI CSI-2 blocks in device-tree.

This series is based atop Christophe JAILLET's fixes at:
