Merge tag 'omap-for-v4.8/ir-rx51-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/drivers

Merge "omap ir-rx51 driver fixes for multiarch for v4.8 merge window"
from Tony Lindgren:

Fix a long time regression for ir-rx51 driver for n900 device tree
booting.

This driver has been unusable with multiarch because of the hardware
timer access. With the recent PWM changes, we can finally fix the
driver for multiarch and device tree support. And naturally there
is no rush for these for the -rc cycle, these can wait for the
merge window.

The PWM changes have been acked by Thierry. For the media changes
I did not get an ack from Mauro but he was Cc'd in the discussion
and these changes do not conflict with other media changes.

After this series we can drop the remaining omap3 legacy booting
board files finally.

* tag 'omap-for-v4.8/ir-rx51-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ir-rx51: use hrtimer instead of dmtimer
  ir-rx51: add DT support to driver
  ir-rx51: use PWM framework instead of OMAP dmtimer
  pwm: omap-dmtimer: Allow for setting dmtimer clock source
  ir-rx51: Fix build after multiarch changes broke it
