[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

+Optional properties for ISC:
+- bus-type
+	When set to 6, Bt.656 decoding (embedded sync) with CRC decoding
+	is enabled. If omitted, then the default bus-type is parallel and
+	the additional properties to follow can be specified:
+- hsync-active
+	Active state of the HSYNC signal, 0/1 for LOW/HIGH respectively.
+	If unspecified, this signal is set as active HIGH.
+- vsync-active
+	Active state of the VSYNC signal, 0/1 for LOW/HIGH respectively.
+	If unspecified, this signal is set as active HIGH.
+- pclk-sample
+	Sample data on rising (1) or falling (0) edge of the pixel clock
+	signal. If unspecified, data is sampled on the rising edge.

 ISC supports a single port node with parallel bus. It should contain one
 'port' child node with child 'endpoint' node. Please refer to the bindings
 defined in Documentation/devicetree/bindings/media/video-interfaces.txt.
