[RESEND,v3,00/17] media: imx: Create media links in bound notifiers

Message

Steve Longerbeam Feb. 15, 2020, 7:41 p.m. UTC

Move media link creation into the notifier bound callbacks in the
minimum set of subdevices required by imx (imx5/6/7 CSI,
imx6/7 MIPI CSI-2, and video mux).

History:

v3:
- The changes to the default behaviour in media_entity_get_fwnode_pad(),
  and the fixes to current media drivers that call it inconsistently, have
  been put-off to another time. Instead this version implements the
  get_fwnode_pad operation where required in the imx and video-mux
  subdevices to make media link creation work correctly. The
  improvements to media_entity_get_fwnode_pad() can wait to another
  patch series.

v2:
- rename/move the notifier-to-state inlines in imx7-mipi-csis.c and
  imx7-media-csi.c, suggested by Rui Silva.
- rewrite imx_media_create_links() to only add the missing media links
  from the imx6 MIPI CSI-2 receiver.
