Subject: [PATCH 0/2] ZII RAVE platform driver

Hi everyone,

This patch series is a driver for supervisory processor found on RAVE
series of devices from ZII. Supervisory processor is a PIC
microcontroller connected to various electrical subsystems on RAVE
devices whose firmware implements protocol to command/qery them.

I originally submitted this driver to MFD sybsystemd[mfdv1], but it
was suggested I add this driver to platform tree instead.

I suspect "bindings/mfd" is not the right place for bindings
information, but I wasn't sure if I should create "bindings/platform"
or "bindings/rave" to place that file into, so I left things as they
originally were hoping to fix this in next version of the patchset.

NOTE:

 * The driver for "zii,rave-sp-watchdog" exists, but I haven't
   submitted it yet, becuase I wanted to make sure that API exposed by
   this MFD is acceptable and doesn't need drastic changes.

 * This driver is dependent on crc_ccitt_false() introduced in
   2da9378d531f8cc6670c7497f20d936b706ab80b in 'linux-next'

Feedback is greatly appreciated!

Thanks,
Andrey Smirnov
