+ In the Linux pinctrl binding, the pin configuration nodes need not be
+ direct children of the pin controller device (may be grandchildren for
+ example). It is define is each individual pin controller device.
+ Say Y here if you want to keep this behavior with the pinconfig
+ u-class: all sub are recursivelly bounded.
+ If the option is disabled, this behavior is deactivated and only
+ the direct children of pin controller will be assumed as pin
+ configuration; you can save memory footprint when this feature is
