[4/4] ARM: dts: AM4372: Add the wkup_m3_ipc node

Add the Wakeup M3 IPC device node for the wkup_m3_ipc driver on
AM4372 SoC. This node uses the IPC registers, part of the Control
Module, and is therefore added as a child of the scm node.

Applying the last two patches in this series into omap-for-v4.3/dt
thanks.

Probably the send-no-irq quirk you can do in the driver based
on the compatible flag like I suggested in the related mailbox
thread so not applying those until that's been discussed.

Regards,

Tony

Now that this compatible flag for the mbox driver has been accepted 
here: 8e3c5952144f ("mailbox/omap: Add ti,mbox-send-noirq quirk to fix 
AM33xx CPU Idle") can the first two patches in this series get picked 
up. I tested applying to v4.4 and they still apply cleanly.

Regards,
Dave

OK applying into omap-for-v4.5/fixes thanks.
