+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.
