[PATCH v5 0/4] DCMI BT656 parallel bus mode support

[Hugues Fruchet]

Add support of BT656 embedded synchronization bus.
This mode allows to save hardware synchro lines hsync & vsync
by replacing them with synchro codes embedded in data stream.
Add "bus-type" property and make it required so that there is no
ambiguity between parallel mode (bus-type=5) and BT656 mode (bus-type=6).

version 5:
  - Add revisited bindings and devicetree with explicit use of "bus-type"

version 4:
  - Fix typo in commit message

version 3:
  - Fix bus_width print to %u as per Sakari comment

version 2:
  - As per Sakari remark, revisit commit message and document
    BT656 parallel bus mode in bindings

version 1:
  - Initial submission
