Subject: [PATCH v2 00/10] Allwinner sunxi message box support

This series adds support for the "hardware message box" in sun8i, sun9i,
and sun50i SoCs, used for communication with the ARISC management
processor (the platform's equivalent of the ARM SCP). The end goal is to
use the arm_scpi driver as a client, communicating with firmware running
on the ARISC CPU, or to use the mailbox to forward NMIs that the
firmware picks up from R_INTC.

Changes from v1:
  - Marked message box clocks as critical instead of hacks in the driver
  - 8 unidirectional channels instead of 4 bidirectional pairs
  - Use per-SoC compatible strings and an A31 fallback compatible
  - Dropped the mailbox framework patch
  - Include DT patches for SoCs that document the message box
