Subject[PATCH 0/2] mailbox: imx: support new tx doorbell
Date
The new added channel type is for i.MX95 SCMI mailbox usage.

i.MX95 using TX doorbell and RX doorbell for the SCMI mailbox transport.
For TX doorbell, we relies on software reply from the other side in
SCMI driver side using mbox_client_txdone to drive the tx tick.

But the current MU tx doorbell using tasklet to emulate hardware ACK
from mailbox driver side, so add a new doorbell type to support i.MX95
SCMI mailbox transport.
