e3a98ac476 Merge branch 'mailbox-for-next' of git://git.linaro.org/landing-teams/working/fujitsu/integration 
Pull mailbox updates from Jassi Brar:
 "Mainly we move from jiffy based timer to HRTIMER for finer control
  over polling.  Then a controller reduces its polling period from 10 to
  1ms"

* 'mailbox-for-next' of git://git.linaro.org/landing-teams/working/fujitsu/integration:
  mailbox: arm_mhu: reduce txpoll_period from 10ms to 1 ms
  mailbox: switch to hrtimer for tx_complete polling
  mailbox: Drop owner assignment from platform_driver

86e488adaa mailbox: arm_mhu: reduce txpoll_period from 10ms to 1 ms 
Since the mailbox core users hrtimers now, it can handle much higher
resolutions. We can reduce the txpoll_period to 1 ms as the transmit
usually takes just few microseconds.

05ae797566 mailbox: Make mbox_chan_ops const 
The mailbox controller's channel ops ought to be read-only.  Update
all the mailbox drivers to make their mbox_chan_ops const as well.
