Description:
Reading this file returns a list of available protocols to use
for the wakeup filter, something like:
- "rc5 rc6 nec jvc [sony]"
+ "rc-5 nec nec-x rc-6-0 rc-6-6a-24 [rc-6-6a-32] rc-6-mce"
+ Note that protocol variants are listed, so "nec", "sony",
+ "rc-5", "rc-6" have their different bit length encodings
+ listed if available.
The enabled wakeup protocol is shown in [] brackets.
- Writing "+proto" will add a protocol to the list of enabled
- wakeup protocols.
- Writing "-proto" will remove a protocol from the list of enabled
- wakeup protocols.
+ Only one protocol can be selected at a time.
Writing "proto" will use "proto" for wakeup events.
Writing "none" will disable wakeup.
Write fails with EINVAL if an invalid protocol combination or

+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 at least one port child node
+with child 'endpoint' node. 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 {
+ vpif_ch0: endpoint@0 {
+ reg = <0>;
+ bus-width = <8>;
+ remote-endpoint = <&composite>;
+ };
+
+ vpif_ch1: endpoint@1 {
+ reg = <1>;
+ bus-width = <8>;
+ data-shift = <8>;
+ };
+ };
+ };
+
+[ ... ]
+
+&i2c0 {
+
+ tvp5147@5d {
+ compatible = "ti,tvp5147";
+ reg = <0x5d>;
+ status = "okay";
+
+ port {
+ composite: endpoint {
+ hsync-active = <1>;
+ vsync-active = <1>;
+ pclk-sample = <0>;
+
+ /* VPIF channel 0 (lower 8-bits) */
+ remote-endpoint = <&vpif_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>;
+ };
+ };
+ };
