Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

This is a v4l2 subdev driver supporting the TDA1997x HDMI video receiver.

I've tested this on a Gateworks GW54xx/GW551x with an IMX6Q/IMX6DL which
uses the TDA19971 with 16bits connected to the IMX6 CSI and single-lane
I2S audio providing 2-channel audio.

For this configuration I've tested both 16bit YUV422 and 8bit
BT656 parallel video bus modes.

While the driver should support the TDA1993 I do not have one for testing.

Further potential development efforts include:
- CEC support
- HDCP support
- TDA19972 support (2 inputs)

Media graphs can be found at http://dev.gateworks.com/docs/linux/media

See details below for configuration and compliance tests
