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@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;
};
