[PATCH v9 13/22] pinctrl: add a pincontrol driver for BCM6362

From: Álvaro Fernández Rojas
Date: Wed Mar 24 2021 - 04:21:16 EST

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.
