In order GPIOS from this controller to be used with the "gpio-hogs"
property, the tca6416 node has to properly labeled as a gpio-controller,
and use #gpio-cells.
With that, the SEL_A, SEL_B, SEL_C lines that are used to select VPIF
input can be configured using GPIO hogs.
As an example, example, the configuration below selects the analog video
input on the da850-evm UI board:
&tca6416 {
status = "okay";
sel_a {
gpio-hog;
gpios = <7 GPIO_ACTIVE_HIGH>;
output-high;
line-name = "ADC_ENn";
};
sel_b {
gpio-hog;
gpios = <6 GPIO_ACTIVE_HIGH>;
output-high;
line-name = "CAMERA_ENn";
};
sel_c {
gpio-hog;
gpios = <5 GPIO_ACTIVE_HIGH>;
output-low;
line-name = "VIDEO_IN_ENn";
};
};
