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. This driver supports the board
controller chip on the Lochnagar board.
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.

These codecs have a variable number of I/O lines each of which
is individually selectable to a wide range of possible functions.
The functionality is slightly different from the traditional muxed
GPIO since most of the functions can be mapped to any pin (and even
the same function to multiple pins). Most pins have a dedicated
"alternate" function that is only available on that pin. The
alternate functions are usually a group of signals, though it is
not always necessary to enable the full group, depending on the
alternate function and how it is to be used. The mapping between
alternate functions and GPIO pins varies between codecs depending
on the number of alternate functions and available pins.
