Texas Instruments VPIF
----------------------
The TI Video Port InterFace (VPIF) is the primary component for video
capture and display on the DA850/AM18x family of TI DaVinci/Sitara
SoCs.
TI Document reference: SPRUH82C, Chapter
35

Required properties:
- compatible: Texas Instruments
- --------------
- interrupts: should contain IRQ line for the VPIF
Video Capture:
VPIF has a
16-bit parallel bus input, supporting
2 8-bit channels or a
single
16-bit channel. It should contain one or two port child nodes
with child 'endpoint' node. If there are two ports then port@
0 must
describe the input and port@
1 output channels. Please refer to the
bindings defined in
Documentation/devicetree/bindings/media/video-interfaces.txt.
Example using
2 8-bit input channels, one of which is connected to an
I2C-connected TVP5147 decoder:
vpif: vpif@
217000 {
compatible = "ti,da850-vpif";
reg = <
0x217000
0x1000>;
interrupts = <

bus-width = <

}
