Merge tag 'dt2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull arm-soc Marvell Orion device-tree updates from Olof Johansson: "This contains a set of device-tree conversions for Marvell Orion platforms that were staged early but took a few tries to get the branch into a format where it was suitable for us to pick up. Given that most people working on these platforms are hobbyists with limited time, we were a bit more flexible with merging it even though it came in late." * tag 'dt2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (21 commits) ARM: Kirkwood: Replace mrvl with marvell ARM: Kirkwood: Describe GoFlex Net LEDs and SATA in DT. ARM: Kirkwood: Describe Dreamplug LEDs in DT. ARM: Kirkwood: Describe iConnects LEDs in DT. ARM: Kirkwood: Describe iConnects temperature sensor in DT. ARM: Kirkwood: Describe IB62x0 LEDs in DT. ARM: Kirkwood: Describe IB62x0 gpio-keys in DT. ARM: Kirkwood: Describe DNS32? gpio-keys in DT. ARM: Kirkwood: Move common portions into a kirkwood-dnskw.dtsi ARM: Kirkwood: Replace DNS-320/DNS-325 leds with dt bindings ARM: Kirkwood: Describe DNS325 temperature sensor in DT. ARM: Kirkwood: Use DT to configure SATA device. ARM: kirkwood: use devicetree for SPI on dreamplug ARM: kirkwood: Add LS-XHL and LS-CHLv2 support ARM: Kirkwood: Initial DTS support for Kirkwood GoFlex Net ARM: Kirkwood: Add basic device tree support for QNAP TS219. ATA: sata_mv: Add device tree support ARM: Orion: DTify the watchdog timer. ARM: Orion: Add arch support needed for I2C via DT. ARM: kirkwood: use devicetree for orion-spi ...
