mtd: add device-tree support to spear_smi
This patch adds support to configure the SPEAr SMI driver via device-tree instead of platform_data. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

+* SPEAr SMI
+
+Required properties:
+- compatible : "st,spear600-smi"
+- reg : Address range of the mtd chip
+- #address-cells, #size-cells : Must be present if the device has sub-nodes
+ representing partitions.
+- interrupt-parent: Should be the phandle for the interrupt controller
+ that services interrupts for this device
+- interrupts: Should contain the STMMAC interrupts
+- clock-rate : Functional clock rate of SMI in Hz
+
+Optional properties:
+- st,smi-fast-mode : Flash supports read in fast mode
+
+Example:
+
+ smi: flash@fc000000 {
+ compatible = "st,spear600-smi";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ reg = <0xfc000000 0x1000>;
+ interrupt-parent = <&vic1>;
+ interrupts = <12>;
+ clock-rate = <50000000>; /* 50MHz */
+
+ flash@f8000000 {
+ st,smi-fast-mode;
+ ...
+ };
+ };
