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;
|
|
};
