This patch-set introduces the CAIF protocol driver for shared memory
over mailbox for u5500.
It implements the driver for transporting CAIF frames between the DB5500
modem portion and host side for the u5500 architecture.
The patches depends on the patch-set "U5500 mailbox driver and
modem irq handler" submitted on the linux-arm-kernel list by Stefan Nilsson.
http://www.arm.linux.org.uk/developer/patches/viewpatch.p...
These patches applies cleanly on latest linux-next git, but depends on
the U5500 mailbox driver for compilation.
Please note that the size and address of the shared memory are specified as module
parameters: shm_total_size, shm_start.
Regards,
Sjur Braendeland
