This patch set adds restool support in fsl-mc bus along
with a rescan attribute to the root DPRC container.
Changes in v2:
- changed mc_command in fsl_mc_command structure
- updated fsl_mc_command to use the proper types and moved it in uapi
- added proper sysfs documentation
Ioana Ciornei (6):
bus: fsl-mc: change mc_command in fsl_mc_command
bus: fsl-mc: move fsl_mc_command struct in a uapi header
bus: fsl-mc: add fsl_mc_allocator cleanup function
bus: fsl-mc: add restool userspace support
bus: fsl-mc: add root dprc rescan attribute
bus: fsl-mc: add bus rescan attribute

Introduce the rescan attribute as a bus attribute to
synchronize the fsl-mc bus objects and the MC firmware.
To rescan the fsl-mc bus, e.g.,
echo 1 > /sys/bus/fsl-mc/rescan

1.9.1
Adding kernel support for restool, a userspace tool for resource
management, means exporting an ioctl capable device file representing
the root resource container.
This new functionality in the fsl-mc bus driver intends to provide
restool an interface to interact with the MC firmware.
Commands that are composed in userspace are sent to the MC firmware
through the RESTOOL_SEND_MC_COMMAND ioctl.
By default the implicit MC I/O portal is used for this operation,
but if the implicit one is busy, a dynamic portal is allocated and then
freed upon execution.

- split the bus/driver changes in a separate patch
- moved the ioctl in the uapi header file
