+Andestech ATCPIT100 timer
+------------------------------------------------------------------
+ATCPIT100 is a generic IP block from Andes Technology, embedded in
+Andestech AE3XX platforms and other designs.
+
+This timer is a set of compact multi-function timers, which can be
+used as pulse width modulators (PWM) as well as simple timers.
+
+It supports up to 4 PIT channels. Each PIT channel is a
+multi-function timer and provide the following usage scenarios:
+One 32-bit timer
+Two 16-bit timers
+Four 8-bit timers
+One 16-bit PWM
+One 16-bit timer and one 8-bit PWM
+Two 8-bit timer and one 8-bit PWM
+
+Required properties:
+- compatible : Should be "andestech,atcpit100"
+- reg : Address and length of the register set
+- interrupts : Reference to the timer interrupt
+- clocks : a clock to provide the tick rate for "andestech,atcpit100"
+- clock-names : should be "PCLK" for the peripheral clock source.
+
+Examples:
+
+timer0: timer@f0400000 {
+ compatible = "andestech,atcpit100";
+ reg = <0xf0400000 0x1000>;
+ interrupts = <2>;

+* ARM Timer Watchdog
+
+ARM 11MP, Cortex-A5 and Cortex-A9 are often associated with a per-core
+Timer-Watchdog (aka TWD), which provides both a per-cpu local timer
+and watchdog.
+
+The TWD is usually attached to a GIC to deliver its two per-processor
+interrupts.
+
+** Timer node required properties:
+
+- compatible : Should be one of:
+ "arm,cortex-a9-twd-timer"
+ "arm,cortex-a5-twd-timer"
+ "arm,arm11mp-twd-timer"
+
+- interrupts : One interrupt to each core
+
+- reg : Specify the base address and the size of the TWD timer
+ register window.
+
+Optional
+
+- always-on : a boolean property. If present, the timer is powered through
+ an always-on power domain, therefore it never loses context.
+
+Example:
+
+ twd-timer@2c000600 {
+ compatible = "arm,arm11mp-twd-timer"";
+ reg = <0x2c000600 0x20>;
+ interrupts = <1 13 0xf01>;

+ "arm,arm11mp-twd-wdt"
+
+- interrupts : One interrupt to each core
+
+- reg : Specify the base address and the size of the TWD watchdog
+ register window.
+
+Example:
+
+ twd-watchdog@2c000620 {

+BCM2835 System Timer
+
+The System Timer peripheral provides four 32-bit timer channels and a

+free running counter values, and generates an interrupt.

+- reg : Specifies base physical address and size of the registers.
+- interrupts : A list of 4 interrupt sinks; one per timer channel.

+- reg: Memory region(s) for timer/clocksource registers. For SMP,

+- interrupts: An interrupt to assign for the timer. The actual pit

+description: |+
+ The Samsung's Multi Core Timer (MCT) module includes two main blocks, the

+ up-counter and can generate 4 interrupts when the counter reaches one of the

+ down-counters and generate an interrupt when the counter expires. There is
+ one CPU local timer instantiated in MCT for every CPU in the system.
