From: Ken Sloat <ksloat@xxxxxxxxxxxxxx> Update device tree binding documentation specifying how to enable BT656 with CRC decoding and specify properties for default parallel bus type. Signed-off-by: Ken Sloat <ksloat@xxxxxxxxxxxxxx> --- Changes in v2: -Use correct media "bus-type" dt property. Changes in v3: -Specify default bus type. -Document optional parallel bus flags. .../devicetree/bindings/media/atmel-isc.txt | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/Documentation/devicetree/bindings/media/atmel-isc.txt b/Documentation/devicetree/bindings/media/atmel-isc.txt index bbe0e87c6188..db3749a3964f 100644 --- a/Documentation/devicetree/bindings/media/atmel-isc.txt +++ b/Documentation/devicetree/bindings/media/atmel-isc.txt @@ -21,6 +21,21 @@ Required properties for ISC: - pinctrl-names, pinctrl-0 Please refer to pinctrl-bindings.txt. +Optional properties for ISC: +- bus-type + When set to 6, Bt.656 decoding (embedded sync) with CRC decoding + is enabled.
