+         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
+         no needed.
