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:
