[PATCH RFC 0/2] Add Renesas RPC-IF support

[Sergei Shtylyov <sergei.shtylyov@xxxxxxxxxxxxxxxxxx>]

Hello!

Here's a set of 2 patches against the 'for-mfd-next' branch of Lee Jones's
'mfd.git' repo. Renesas Reduced Pin Count Interface (RPC-IF) allows a SPI
flash or HyperFlash connected to the SoC to be accessed via the external
address space read mode or the manual mode. The MFD driver for RPC-IF
registers either the SPI or HyperFLash subdevice, depending on the contents
of the device tree subnode; it also provides the absract "back end" API
that can be used by the "front end" SPI/MTD drivers to talk to the real
hardware... The HyperFlash subdriver isn't ready yet, so the MFD driver
may need some updates in order to serve it, hence the RFC status...

Based on the original patch by Mason Yang <masonccyang@xxxxxxxxxxx>.
