Cover letter [PATCH 0/3] Intel MSIC MFD driver for Medfield platform
Hi,
This series adds support for the Intel MSIC (Mixed Signal IC) chip found on Intel Medfield platforms. The MSIC chip embeds audio codec, ADC, GPIOs etc.
Existing drivers which use plain SCU IPC will continue to work and they can be converted to the MSIC register interface later on. Any new drivers for devices in the MSIC should use this interface.
Thanks.
