[char-misc-next 00/11 V4] Add Client MEI bus and NFC device

From: Tomas Winkler

This is take 4 on the MEI bus + NFC device patches

This patch set adds implementation of MEI CLIENT BUS abstraction
over MEI device, this allows standard Linux device drivers
to access functionality exposed by MEI device clients that was previously
available only to the user space through /dev/mei

The first exercises is to export the NFC radio

More information can be found under


v3 -> v4:
The bus is named mei client bus
- Renames:
* mei_bus_driver to mei_cl_driver
* mei_bus_device to mei_cl_device
v2 -> v3:
- Renames:
* mei_device to mei_host. The mei_host pointers are still called *dev
as I didn't want the first patch to get too fat.
* mei_bus_driver to mei_driver
* mei_bus_client to mei_device

- mei_driver structure changes:
* name pointer addition
* MEI id table
* probe routine now takes the probed MEI id as an argument

- mei-bus.txt update according to the mei_driver changes and the structure
- All exported symbols converted to EXPORT_SYMBOL_GPL.
- to_mei_* macros moved to bus.c
- drivers/misc/mei/bus.h deleted, all API definitions moved to mei_dev.h
- mei_device structure clenup: mei_host, mei_driver, and name fields removed.
- Fixed driver owner: mei_driver_register() is now a macro over
__mei_driver_register, using THIS_MODULE as the default owner.
