v4:
- move include/dt-bindings/media/tda1997x.h to bindings patch
- clarify port node details

v3:
- fix typo

v2:
- add vendor prefix and remove _ from vidout-portcfg

+Device-Tree bindings for the NXP TDA1997x HDMI receiver
+
+The TDA19971/73 are HDMI video receivers.
+
+The TDA19971 Video port output pins can be used as follows:
+ - RGB 8bit per color (24 bits total): R[11:4] B[11:4] G[11:4]
+ - YUV444 8bit per color (24 bits total): Y[11:4] Cr[11:4] Cb[11:4]
+ - YUV422 semi-planar 8bit per component (16 bits total): Y[11:4] CbCr[11:4]
+ - YUV422 semi-planar 10bit per component (20 bits total): Y[11:2] CbCr[11:2]
+ - YUV422 semi-planar 12bit per component (24 bits total): - Y[11:0] CbCr[11:0]
+ - YUV422 BT656 8bit per component (8 bits total): YCbCr[11:4] (2-cycles)
+ - YUV422 BT656 10bit per component (10 bits total): YCbCr[11:2] (2-cycles)
+ - YUV422 BT656 12bit per component (12 bits total): YCbCr[11:0] (2-cycles)
+
+The TDA19973 Video port output pins can be used as follows:
+ - RGB 12bit per color (36 bits total): R[11:0] B[11:0] G[11:0]
+ - YUV444 12bit per color (36 bits total): Y[11:0] Cb[11:0] Cr[11:0]
+ - YUV422 semi-planar 12bit per component (24 bits total): Y[11:0] CbCr[11:0]
+ - YUV422 BT656 12bit per component (12 bits total): YCbCr[11:0] (2-cycles)
+
+The Video port output pins are mapped via 4-bit 'pin groups' allowing
+for a variety of connection possibilities including swapping pin order within
+pin groups. The video_portcfg device-tree property consists of register mapping
+pairs which map a chip-specific VP output register to a 4-bit pin group. If
+the pin group needs to be bit-swapped you can use the *_S pin-group defines.
+
+Required Properties:
+ - compatible :
+ - "nxp,tda19971" for the TDA19971
+ - "nxp,tda19973" for the TDA19973
+ - reg : I2C slave address
+ - interrupts : The interrupt number
+ - DOVDD-supply : Digital I/O supply
+ - DVDD-supply : Digital Core supply
+ - AVDD-supply : Analog supply
+ - nxp,vidout-portcfg : array of pairs mapping VP output pins to pin groups.
+
+Optional Properties:
+ - nxp,audout-format : DAI bus format: "i2s" or "spdif".
+ - nxp,audout-width : width of audio output data bus (1-4).
+ - nxp,audout-layout : data layout (0=AP0 used, 1=AP0/AP1/AP2/AP3 used).
+ - nxp,audout-mclk-fs : Multiplication factor between stream rate and codec
+ mclk.
+
+The port node shall contain one endpoint child node for its digital
+output video port, in accordance with the video interface bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Optional Endpoint Properties:
+ The following three properties are defined in video-interfaces.txt and
+ are valid for the output parallel bus endpoint:
+ - hsync-active: Horizontal synchronization polarity. Defaults to active high.
+ - vsync-active: Vertical synchronization polarity. Defaults to active high.
+ - data-active: Data polarity. Defaults to active high.
+
+Examples:
+ - VP[15:0] connected to IMX6 CSI_DATA[19:4] for 16bit YUV422
+ 16bit I2S layout0 with a 128*fs clock (A_WS, AP0, A_CLK pins)
