Test pin controller pin configuration nodes. Each node is composed by one or

more groups, each defining the configuration for a set of pins.

Test pin controller pin configuration group. Each group contains a list of
|
|
pins sharing the same set of properties. Example:
|
|
|
|
/* node representing default state for test_device0 */
|
|
test_device0_default: test_device0_default {
|
|
/* group 1 (name is arbitrary) */
|
|
pins1 {
|
|
/* configure pins 0 and 1 */
|
|
pins = <0>, <1>;
|
|
/* both pins 0 and 1 have pull-up enabled */
|
|
bias-pull-up;
|
|
};
|
|
...
|
|
/* group N (name is arbitrary) */
|
|
pinsN {
|
|
/* configure pin M */
|
|
pins = <M>;
|
|
/* pin M has pull-down enabled */
|

bias-pull-down;

The list of supported standard properties:

|
|
|
- bias-pull-up: Enable pull-up resistor.

- bias-pull-down: Enable pull-down resistor.

An array of pins sharing the same group properties. Each entry is a

32-bit integer that is just used to identify the entry for testing

purposes.
