Subject[PATCH 0/6] rpmsg: enable the use of the rpmsg_char device for the Virtio backend
Date
This series is the first step in the division of the series: 
"Introduce a generic IOCTL interface for RPMsg channels management"[1]

The main goal here is to enable the RPMsg char interface for
the virtio RPMsg backend.

In addition some patches have been includes in order to document the
interface and rename the rpmsg_char_init function.

It also includes Mathieu Poirier's comments made on [1]

Patchsets that should be the next steps:
- Extract the control part of the char dev and create the rpmsg_ctrl.c
file
- Introduce the RPMSG_CREATE_DEV_IOCTL IOCTL to instantiate RPMsg devices
