Paul Burton fb615d61b5 Update MIPS email addresses
MIPS will soon not be a part of Imagination Technologies, and as such
many @imgtec.com email addresses will no longer be valid. This patch
updates the addresses for those who:

 - Have 10 or more patches in mainline authored using an @imgtec.com
   email address, or any patches dated within the past year.

 - Are still with Imagination but leaving as part of the MIPS business
   unit, as determined from an internal email address list.

 - Haven't already updated their email address (ie. JamesH) or expressed
   a desire to be excluded (ie. Maciej).

 - Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt &
   myself.

New addresses are of the form firstname.lastname@mips.com, and all
verified against an internal email address list.  An entry is added to
.mailmap for each person such that get_maintainer.pl will report the new
addresses rather than @imgtec.com addresses which will soon be dead.

Instances of the affected addresses throughout the tree are then
mechanically replaced with the new @mips.com address.

What: /sys/class/remoteproc/.../firmware
Date: October 2016
Contact: Matt Redfearn <matt.redfearn@mips.com>
Description: Remote processor firmware
Reports the name of the firmware currently loaded to the
remote processor.
To change the running firmware, ensure the remote processor is
stopped (using /sys/class/remoteproc/.../state) and write a new filename.
What: /sys/class/remoteproc/.../state
Date: October 2016
Contact: Matt Redfearn <matt.redfearn@mips.com>
Description: Remote processor state
Reports the state of the remote processor, which will be one of:
"offline"
"suspended"
"running"
"crashed"
"invalid"
"offline" means the remote processor is powered off.
"suspended" means that the remote processor is suspended and
must be woken to receive messages.
"running" is the normal state of an available remote processor
"crashed" indicates that a problem/crash has been detected on
the remote processor.
"invalid" is returned if the remote processor is in an
unknown state.
Writing this file controls the state of the remote processor.
The following states can be written:
"start"
"stop"
Writing "start" will attempt to start the processor running the
firmware indicated by, or written to,
/sys/class/remoteproc/.../firmware. The remote processor should
transition to "running" state.
Writing "stop" will attempt to halt the remote processor and
return it to the "offline" state.
