Merge tag 'lpc18xx_dts_for_4.4' of https://github.com/manabian/linux-lpc into next/dt
Pull "Device Tree additions for NXP LPC18xx platform" from Joachim Eastwood:
- Reset controller (RGU)
- DMA controller and mux
- SPI Flash (SPIFI) controller
- I2C controller
- Watchdog and SCT PWM from Ariel D'Alessandro
And board updates for EA4357 dev kit and Hitex LPC4350 eval board
adding I2C, SPIFI Flash and some miscellaneous stuff.
