From: 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@xxxxxxxxxxxxx/

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
