On 32 bit ARM parts, handle in the same way as syscon. On 64 bit ARM parts, the System Manager can only be accessed by EL3 secure mode. Since a SMC call to EL3 is required, this new driver uses regmaps similar to syscon to handle the SMC call. Since regmaps abstract out the underlying register access, the changes to drivers accessing the System Manager are minimal.

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. Audio system topology, clocking and power can all be controlled through the Lochnagar controller chip, allowing the device under test to be used in a variety of possible use cases. As the Lochnagar is a fairly complex device this MFD driver allows the drivers for the various features to be bound in. Initially clocking, regulator and pinctrl will be added as these are necessary to configure the system. But in time at least audio and voltage/current monitoring will also be added.
