[PATCH v2 0/2] Apple Mailbox Controller support

[Sven Peter]

Hi,

This is the second version of my series which adds support for the mailbox
controllers found on the Apple M1.

v1: https://lore.kernel.org/lkml/20210907145501.69161-1-sven@svenpeter.dev/

Thanks to Jassi, Mark and Alyssa for the initial review. I've addressed
your comments with the following changes:

 - switched to txdone_irq instead of introducing a new mode
 - switched to a threaded interrupt handler for receiving messages
 - added co-processor examples to the device tree binding 
 - reformatted the register defines and clarified multiple comments

Best,

Sven
