-Subject: [PATCH 09/16] pinctrl: add a pincontrol driver for BCM6362
-
-Add a pincotrol driver for BCM6362. BCM6362 allows muxing individual
-GPIO pins to the LED controller, to be available by the integrated
-wifi, or other functions. It also supports overlay groups, of which
-only NAND is documented.
