The Phytium mailbox controller that has a channel/link to communicate
|
|
with the remote end. A link raises interrupt for any received data. However,
|
|
there is no specified way of knowing if the sent data has been read by the
|
|
remote. This driver assumes the sender polls STAT register and the remote
|
|
clears it after having read the data.
