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";
};
};

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
