Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC device tree conversions from Arnd Bergmann:
"These are device tree conversions for a number of platforms, with the
intention of turning code from board files into device tree
descriptions. Notable changes are:
- davinci bindings for pinctrl, MTD, RTC, watchdog and i2c
- nomadik bindings for all devices, removing the board files
- bcm2835 bindings for mmc and i2c
- tegra bindings for hdmi, keyboard, audio, as well as some updates
- at91 bindings for hardware ecc and for devices on RM9200
- mxs bindings for cfa100xx
- sunxi support for Miniand Hackberry board"
