Subject: [PATCH v4 0/2] add VCP mailbox driver

Since the reviewer hopes to combine the VCP IPC driver and
the VCP driver for a unified review, the original three patches
have been split into two parts: the VCP mailbox driver and
the binding remain together, while the VCP IPC driver is merged
with the VCP driver and submitted as one.

To prevent the information discussed in the previous cover letter
from being lost, the previous link is attached.
