The mailbox framework abstracts hardware mailboxes and @data
should be the data to be written to the hardware.

Using the void * to pass composite data types means that the client and
provider are tightly coupled and as such the mailbox framework does not
provide you any abstraction.

You also only expose a single channel, so a direct function call between
the two specific drivers would be a better fit.

Regards,
Bjorn
