Freescale FlexTimer Module (FTM) PWM controller
|
|
|
|
Required properties:
|
|
- compatible: Should be "fsl,vf610-ftm-pwm".
|
|
- reg: Physical base address and length of the controller's registers
|
|
- #pwm-cells: Should be 3. See pwm.txt in this directory for a description of
|
|
the cells format.
|
|
- clock-names: Should include the following module clock source entries:
|
|
"ftm_sys" (module clock, also can be used as counter clock),
|
|
"ftm_ext" (external counter clock),
|
|
"ftm_fix" (fixed counter clock),
|
|
"ftm_cnt_clk_en" (external and fixed counter clock enable/disable).
|
|
- clocks: Must contain a phandle and clock specifier for each entry in
|
|
clock-names, please see clock/clock-bindings.txt for details of the property
|
|
values.
|
|
- pinctrl-names: Must contain a "default" entry.
|
|
- pinctrl-NNN: One property must exist for each entry in pinctrl-names.
|
|
See pinctrl/pinctrl-bindings.txt for details of the property values.

|
|
Example:
|
|
|
|
pwm0: pwm@40038000 {
|
|
compatible = "fsl,vf610-ftm-pwm";
|
|
reg = <0x40038000 0x1000>;
|
|
#pwm-cells = <3>;
|
|
clock-names = "ftm_sys", "ftm_ext",
|
|
"ftm_fix", "ftm_cnt_clk_en";
|
|
clocks = <&clks VF610_CLK_FTM0>,
|
|
<&clks VF610_CLK_FTM0_EXT_SEL>,
|
|
<&clks VF610_CLK_FTM0_FIX_SEL>,
|
|
<&clks VF610_CLK_FTM0_EXT_FIX_EN>;
|
|
pinctrl-names = "default";
|
|
pinctrl-0 = <&pinctrl_pwm0_1>;
|
|
};
