mfd: si476x: Add header files and Kbuild plumbing
This patch adds all necessary header files and Kbuild plumbing for the core driver for Silicon Laboratories Si476x series of AM/FM tuner chips. The driver as a whole is implemented as an MFD device and this patch adds a core portion of it that provides all the necessary functionality to the two other drivers that represent radio and audio codec subsystems of the chip.

This is the core driver for the SI476x series of AM/FM
|

|
radio. This MFD driver connects the radio-si476x V4L2 module
|
||||||
|
and the si476x audio codec.
|
||||||
|
|

|
To compile this driver as a module, choose M here: the

module will be called si476x-core.
