Merge tag 'omap-for-v4.2/dt-pt1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt

Merge "Device tree related changes for omaps" from Tony Lindgren:

- Configure MMC data lines 4..8 for 1.8V IO on boards that
  are using them as GPIOs instead of MMC data lines

- Add support for Baltos IR5221

- Add device tree support for LogicPD Torpedo devkit

- Add 3717 core pinctrl region

- Add gta04 1w and GSM audio support

- Add wilink and ov2659 support for am437x-gp-evm

- Add am335x-evm bluetooth and mmc3 support

- Enable omap5-uevm uart wakeup interrupt

- Enable I2C2 on BeagleBone as it's used for the capes

- Use defines for LDP GPIO keys
