  ==== ADV7842 Example ====

    * Put 720p output to ADV7842 HDMI port A, and use v4l2_video_capture t
o capture video file on BF609-EZKIT.

-   * Config the related gpio as shown below on target board:

-       - echo 150 > /sys/class/gpio/export

-       - echo out > /sys/class/gpio/gpio150/direction

-       - echo 0 > /sys/class/gpio/gpio150/value

-       - echo 152 > /sys/class/gpio/export

-       - echo out > /sys/class/gpio/gpio152/direction

-       - echo 0 > /sys/class/gpio/gpio152/value

-   * Generated yuv file can be played by raw sequence file player, for ex
ample pYUV. Or it can be as the input of ADV7511.PYUV must be config as sh
own below:

-       - Resolution -> HD720

-       - Color space -> YCbCr

-       - Subsampling -> 4:2:2

-       - Ordering -> UYVY

-   and select Interleaved option at the same time.

+   * Config the related gpio as shown below on target board:<code>

+ echo 150 > /sys/class/gpio/export
