From: "qipeng.zha" <qipeng....@intel.com>
Add MFD core driver for Intel Broxton Whiskey Cove PMIC,
which is specially accessed by hardware IPC, not a generic
I2C device
Signed-off-by: qipeng.zha <qipeng....@intel.com>
---
change in v4
add compile dependency to PMC IPC driver in Makefile, or will
use NULL stubs defined in PMC IPC header file;
change in v3
implement ipc regmap r/w callback in pmic driver, since there dropped
before patch of implement virtual ipc support in regmap core;
update some function's comment;
