Merge tag 'omap-for-v4.1/wl12xx-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt

Merge "wireless wl12xx and omap device tree changes for v4.1" from Tony
Lindgren:

Wireless and omap changes to make wl12xx driver to use device tree
data instead of platform data from Eliad Peller <eliad@wizery.com>:

- Add device-tree support to the wlcore (wl12xx/wl18xx) driver.

- Update the current users to use the bindings instead of pdata-quirks.

- Finally, remove the deprecated wl12xx_platform_data struct

Note that da850 board file code that still uses the platform data,
but we have da850.dtsi that can be used instead. So it was decided
that we should try to remove the wl12xx support from the da850
board file as suggested by Sekhar Nori <nsekhar@ti.com>. As it's
the last patch in the series, the last patch can be simply reverted
if needed.

As this series touches quite a bit of arch code, it was suggested
by Kalle Valo <kvalo@codeaurora.org> that the whole series should
be merged via the arm-soc tree.

* tag 'omap-for-v4.1/wl12xx-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  wlcore: remove wl12xx_platform_data
  ARM: dts: add wl12xx/wl18xx bindings
  wlcore: add device-tree support
  dt: bindings: add TI's wilink wireless device
  wl12xx: use frequency instead of enumerations for pdata clocks
  wlcore: set irq_trigger in board files instead of hiding behind a quirk
  + Linux 4.0-rc4
