Subject: [PATCH] Mfd: Initial support for Texas Instruments AIC family of CODECs
Initial support for TI's AIC platform and TLV320AIC3262 CODEC device.
The AIC platform provides common interface to series of low power audio CODECS.
This MFD core driver instantiates subdevices that help in supporting range of features
provided by AIC family of devices.
