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 Signed-off-by: Olof Johansson <olof@lixom.net>
