DCMI BT656 parallel bus mode support

expand

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. This mode is enabled when hsync-active & vsync-active fields are not specified in devicetree. =========== = history = =========== version 2: - As per Sakari remark, revisit commit message and document BT656 parallel bus mode in bindings version 1: - Initial submission Hugues Fruchet (2): media: stm32-dcmi: add support of BT656 bus media: dt-bindings: media: st,stm32-dcmi: Add support of BT656 .../devicetree/bindings/media/st,stm32-dcmi.yaml | 30 ++++++++++++++++++ drivers/media/platform/stm32/stm32-dcmi.c | 37 ++++++++++++++++++++-- 2 files changed, 65 insertions(+), 2 deletions(-)
