Since we can include other binding files at any level (child, grand-child, etc.) it makes no sense to maintain two copies of pinctrl props definitions (pincfg-node/pincfg-node-group). Instead, pincfg-node.yaml defines props at root level, and it is included where needed, either child-binding or grandchild-binding. Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no>

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) */
|
|
group1 {
|
|
/* 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) */
|
|
groupN {
|
|
/* configure pin M */
|
|
pins = <M>;
|
|
/* pin M has pull-down enabled */

bias-pull-down;
