Convert the Texas Instruments DA850/AM18x Video Port Interface (VPIF) device tree binding from text format to YAML dt-schema. Add power-domains property missing from text.

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
|
||||
http://www.ti.com/lit/pdf/spruh82
|
||||
|
||||
Required properties:
|
||||
- compatible: must be "ti,da850-vpif"
|
||||
- reg: physical base address and length of the registers set for the device;
|
||||
- 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 = <92>;
|
||||
|
||||
port@0 {
|
||||
vpif_input_ch0: endpoint@0 {
|
||||
reg = <0>;
|
||||
bus-width = <8>;
|
||||
remote-endpoint = <&composite_in>;
|
||||
};
|
||||
|
||||
vpif_input_ch1: endpoint@1 {
|
||||
reg = <1>;
|
||||
bus-width = <8>;
|
||||
data-shift = <8>;
|
||||
};
|
||||
};
|
||||
|
||||
port@1 {
|
||||
vpif_output_ch0: endpoint {
|
||||
bus-width = <8>;
|
||||
remote-endpoint = <&composite_out>;
|
||||
};
|
||||
};
|
||||
};
|
||||
|
||||
[ ... ]
|
||||
|
||||
&i2c0 {
|
||||
|
||||
tvp5147@5d {
|
||||
compatible = "ti,tvp5147";
|
||||
reg = <0x5d>;
|
||||
|
||||
port {
|
||||
composite_in: endpoint {
|
||||
hsync-active = <1>;
|
||||
vsync-active = <1>;
|
||||
pclk-sample = <0>;
|
||||
|
||||
/* VPIF channel 0 (lower 8-bits) */
|
||||
remote-endpoint = <&vpif_input_ch0>;
|
||||
bus-width = <8>;
|
||||
};
|
||||
};
|
||||
};
|
||||
|
||||
adv7343@2a {
|
||||
compatible = "adi,adv7343";
|
||||
reg = <0x2a>;
|
||||
|
||||
port {
|
||||
composite_out: endpoint {
|
||||
adi,dac-enable = <1 1 1>;
|
||||
adi,sd-dac-enable = <1>;
|
||||
|
||||
remote-endpoint = <&vpif_output_ch0>;
|
||||
bus-width = <8>;
|
||||
};
|
||||
};
|
||||
};
|
||||
};
|
||||
|
||||
|
||||
Alternatively, an example when the bus is configured as a single
|
||||
16-bit input (e.g. for raw-capture mode):
|
||||
|
||||
vpif: vpif@217000 {
|
||||
compatible = "ti,da850-vpif";
|
||||
reg = <0x217000 0x1000>;
|
||||
interrupts = <92>;
|
||||
|
||||
port {
|
||||
vpif_ch0: endpoint {
|
||||
bus-width = <16>;
|
||||
};
|
||||
};
|
||||
};
