Merge branch 'lpc32xx/dt' of git://git.antcom.de/linux-2.6 into next/dt

Roland Stigge <stigge@antcom.de> writes: this is a rearrangement of all mach-lpc32xx specific patches for device tree conversion. Please note that: * It builds upon the i2c-pnx changes (see previous pull request, branch lpc32xx/i2c) * Dave Miller gave permission to merge the lpc_eth.c change via arm-soc (patch 1/8) The rest of the patches is mach-lpc32xx only. * 'lpc32xx/dt' of git://git.antcom.de/linux-2.6: ARM: LPC32xx: Defconfig update ARM: LPC32xx: Move common code to common.c ARM: LPC32xx: Device tree support ARM: LPC32xx: DTS files for device tree conversion ARM: LPC32xx: Remove obsolete platform Kconfig ARM: LPC32xx: clock.c registration adjustment ARM: LPC32xx: clock.c cleanup net: Add device tree support to LPC32xx Signed-off-by: Arnd Bergmann <arnd@arndb.de> [olof: rebuilt branch due to drop of an early merge] Signed-off-by: Olof Johansson <olof@lixom.net>

+* NXP LPC32xx Main Interrupt Controller
+  (MIC, including SIC1 and SIC2 secondary controllers)
+
+Required properties:
+- compatible: Should be "nxp,lpc3220-mic"
+- interrupt-controller: Identifies the node as an interrupt controller.
+- interrupt-parent: Empty for the interrupt controller itself
+- #interrupt-cells: The number of cells to define the interrupts. Should be 2.
+  The first cell is the IRQ number
+  The second cell is used to specify mode:
+      1 = low-to-high edge triggered
+      2 = high-to-low edge triggered
+      4 = active high level-sensitive
+      8 = active low level-sensitive
+      Default for internal sources should be set to 4 (active high).
+- reg: Should contain MIC registers location and length
+
+Examples:
+	/*
+	 * MIC
+	 */
+	mic: interrupt-controller@40008000 {
+		compatible = "nxp,lpc3220-mic";
+		interrupt-controller;
+		interrupt-parent;
+		#interrupt-cells = <2>;

+* NXP LPC32xx SoC Ethernet Controller
+
+Required properties:
+- compatible: Should be "nxp,lpc-eth"
+- reg: Address and length of the register set for the device
+- interrupts: Should contain ethernet controller interrupt
+
+Optional properties:
+- phy-mode: String, operation mode of the PHY interface.
+  Supported values are: "mii", "rmii" (default)
+- use-iram: Use LPC32xx internal SRAM (IRAM) for DMA buffering
+- local-mac-address : 6 bytes, mac address
