Merge tag 'dt2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull "ARM: More device tree support updates" from Olof Johansson: "This branch contains a number of updates for device tree support on several ARM platforms, in particular: * AT91 continues the device tree conversion adding support for a number of on-chip drivers and other functionality * ux500 adds probing of some of the core SoC blocks through device tree * Initial device tree support for ST SPEAr600 platforms * kirkwood continues the conversion to device-tree probing" Manually merge arch/arm/mach-ux500/Kconfig due to MACH_U8500 rename, and drivers/usb/gadget/at91_udc.c due to header file include cleanups. Also do an "evil merge" for the MACH_U8500 config option rename that the affected RMI4 touchscreen driver in staging. It's called MACH_MOP500 now, and it was missed during previous merges. * tag 'dt2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (48 commits) ARM: SPEAr600: Add device-tree support to SPEAr600 boards ARM: ux500: Provide local timer support for Device Tree ARM: ux500: Enable PL022 SSP Controller in Device Tree ARM: ux500: Enable PL310 Level 2 Cache Controller in Device Tree ARM: ux500: Enable PL011 AMBA UART Controller for Device Tree ARM: ux500: Enable Cortex-A9 GIC (Generic Interrupt Controller) in Device Tree ARM: ux500: db8500: list most devices in the snowball device tree ARM: ux500: split dts file for snowball into generic part ARM: ux500: combine the board init functions for DT boot ARM: ux500: Initial Device Tree support for Snowball ARM: ux500: CONFIG: Enable Device Tree support for future endeavours ARM: kirkwood: use devicetree for rtc-mv ARM: kirkwood: rtc-mv devicetree bindings ARM: kirkwood: fdt: define uart[01] as disabled, enable uart0 ARM: kirkwood: fdt: facilitate new boards during fdt migration ARM: kirkwood: fdt: absorb kirkwood_init() ARM: kirkwood: fdt: use mrvl ticker symbol ARM: orion: wdt: use resource vice direct access ARM: Kirkwood: Remove tclk from kirkwood_asoc_platform_data.

+Atmel NAND flash
+
+Required properties:
+- compatible : "atmel,at91rm9200-nand".
+- reg : should specify localbus address and size used for the chip,
+ and if availlable the ECC.
+- atmel,nand-addr-offset : offset for the address latch.
+- atmel,nand-cmd-offset : offset for the command latch.
+- #address-cells, #size-cells : Must be present if the device has sub-nodes
+ representing partitions.
+
+- gpios : specifies the gpio pins to control the NAND device. detect is an
+ optional gpio and may be set to 0 if not present.
+
+Optional properties:
+- nand-ecc-mode : String, operation mode of the NAND ecc mode, soft by default.
+ Supported values are: "none", "soft", "hw", "hw_syndrome", "hw_oob_first",
+ "soft_bch".
+- nand-bus-width : 8 or 16 bus width if not present 8
+- nand-on-flash-bbt: boolean to enable on flash bbt option if not present false
+
+Examples:
+nand0: nand@40000000,0 {
+ compatible = "atmel,at91rm9200-nand";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ reg = <0x40000000 0x10000000
