Move media link creation into the notifier bound callbacks in the
set of subdevices required by imx (imx5/6/7 CSI, imx6/7 MIPI CSI-2
receivers, and video-mux).
Rui, Laurent:
Isn't it true that the imx7 CSI can only ever connect to a CSI mux?
See patch 18/23 which removes imx7_csi_get_upstream_endpoint(), and
19/23.
History:
v5:
- Revived patch "media: entity: Modify default behavior of
media_entity_get_fwnode_pad" from v2.
- Added a v4l2_subdev_get_fwnode_pad_default, which can be used as
a subdev's .get_fwnode_pad() operation if the subdev maps fwnode
port id's and pad indexes 1:1. Used by video-mux, imx6/7 MIPI
CSI-2 receivers, and imx7 CSI.
- Exported imx_media_create_fwnode_pad_link(s) to v4l2-core as
v4l2_create_fwnode_links_to_pad() and v4l2_create_fwnode_links().
Used by the video-mux, imx5/6/7 CSI's, and imx6/7 MIPI CSI-2
receivers in their bound notifiers.
- Introduced a new group id IMX_MEDIA_GRP_ID_CSI_MUX, the imx6/7 CSI's
will set the bound subdev grp_id to this if the bound subdev is a
video mux.
- Removed imx7_csi_get_upstream_endpoint(), replacing with simpler
code, see above.
v4:
- Removed the endpoint parsing callback APIs from video-mux and imx drivers
as suggested by Sakari, replacing with endpoint parsing local to the
drivers and the use of v4l2_async_notifier_add_fwnode_remote_subdev().
As a result convenience function v4l2_async_register_fwnode_subdev()
is no longer used and is reverted.
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.
