SPEAr: Add DT bindings for SPEAr's timer
All SPEAr SoC's use ST's Timer module. This patch adds device tree probing capability for that. Signed-off-by: Viresh Kumar <viresh.kumar@st.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

+* SPEAr ARM Timer
+
+** Timer node required properties:
+
+- compatible : Should be:
+ "st,spear-timer"
+- reg: Address range of the timer registers
+- interrupt-parent: Should be the phandle for the interrupt controller
+ that services interrupts for this device
+- interrupt: Should contain the timer interrupt number
+
+Example:
+
+ timer@f0000000 {
+ compatible = "st,spear-timer";
+ reg = <0xf0000000 0x400>;
+ interrupts = <2>;
+ };
