From: Xiubo Li <Li.Xiubo at freescale.com>
The FTM binding could be used on Vybrid and LS1+, add a binding
document for it.

+Freescale FlexTimer Module (FTM) Timer
+
+Required properties:
+
+- compatible : should be "fsl,ftm-timer"
+- reg : Specifies base physical address and size of the register sets for the
+ clock event device and clock source device.
+- interrupts : Should be the clock event device interrupt.
+- clocks : The clocks provided by the SoC to drive the timer, must contain an
+ entry for each entry in clock-names.
+- clock-names : Must include the following entries:
+ o "ftm-evt"
+ o "ftm-src"
+ o "ftm-evt-counter-en"
+ o "ftm-src-counter-en"
+- big-endian: One boolean property, the big endian mode will be in use if it is
+ present, or the little endian mode will be in use for all the device registers.
+
+Example:
+ftm: ftm at 400b8000 {
+ compatible = "fsl,ftm-timer";
+ reg = <0x400b8000 0x1000 0x400b9000 0x1000>;
+ interrupts = <0 44 IRQ_TYPE_LEVEL_HIGH>;
+ clock-names = "ftm-evt", "ftm-src",
+ "ftm-evt-counter-en", "ftm-src-counter-en";
+ clocks = <&clks VF610_CLK_FTM2>,
+ <&clks VF610_CLK_FTM3>,
+ <&clks VF610_CLK_FTM2_EXT_FIX_EN>,
+ <&clks VF610_CLK_FTM3_EXT_FIX_EN>;
+ big-endian;
+};
