Hi,
Here is the next revision of Mailbox code.
Changes since v3:
o Change name of symbols from ipc to mbox
o Return real types instead of void *
o Align structures
o Change some symbol names
rxcb -> rx_callback
txcb -> tx_done
o Added kernel-doc for exported API
o Dropped t
Convert the PL320 controller driver to work with the common
mailbox API. Also convert the only user of PL320, highbank-cpufreq.c
to work with thee API. Drop the obsoleted driver pl320-ipc.c

For fast TX the complete could be called before being initialized as follows
mbox_send_message --> poll_txdone --> tx_tick --> complete(&chan->tx_complete)
Init the completion early enough to fix the race.

The patch 30058677 "ARM / highbank: add support for pl320 IPC"
added a pl320 IPC specific header file as a generic mailbox.h.
This file has been renamed appropriately to allow the
introduction of the generic mailbox API framework.

Try to delete the timer only if it was init/used.

Hello,
Here is what the generic mailbox api looks like after modifications
to make it work with 5 different platforms.
