Subject[PATCH V2 0/2] mailbox: imx: support RST channel
Date
From: Peng Fan <peng.fan@nxp.com>

V2:
Add R-b tag
Missed to add mailbox maintainer in V1, add in V2

To i.MX generic MU, when linux stop remote core, the MU-B side is not
reset because of hardware design, so MU-B contains valid configuration
when remote core stops. Then when linux start remote core again, linux
may notify remote core before remote core is ready for incoming message.
So we need make sure MU is in reset state before remote core start. So
add a RST channel which is only to reset MU when shutdown the RST mbox
channel.
