[PATCH 4/5] pinctrl: lochnagar: Add support for the Cirrus Logic Lochnagar

Charles Keepax
2018-09-05T10:41:35Z

From: Charles Keepax <ckeepax@opensource.wolfsonmicro.com>

Lochnagar is an evaluation and development board for Cirrus
Logic Smart CODEC and Amp devices. It allows the connection of
most Cirrus Logic devices on mini-cards, as well as allowing
connection of various application processor systems to provide a
full evaluation platform.

Lochnagar provides many pins which can generally be used for an
audio function such as an AIF or a PDM interface, but also as
GPIOs.
