[PATCH 1/1] dt-bindings: pwm: fsl-ftm: Convert to yaml format

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Convert dt-bindings pwm-fsl-ftm.txt to yaml format.

Additional change during convert:
- "big-endian" is not required property.
- Add "sleep" to pinctrl-names.
- Change pinctrl-NNN to pinctrl-0 and pinctrl-1.
- Remove label "pwm0" in example.

-Freescale FlexTimer Module (FTM) PWM controller

-The same FTM PWM device can have a different endianness on different SoCs. The
-device tree provides a property to describing this so that an operating system
-device driver can handle all variants of the device. Refer to the table below
-for the endianness of the FTM PWM block as integrated into the existing SoCs:
-
-	SoC     | FTM-PWM endianness
-	--------+-------------------
-	Vybrid  | LE
-	LS1     | BE
-	LS2     | LE
-
-Please see ../regmap/regmap.txt for more detail about how to specify endian
-modes in device tree.
-
-
-Required properties:
-- compatible : should be "fsl,<soc>-ftm-pwm" and one of the following
-   compatible strings:
-  - "fsl,vf610-ftm-pwm" for PWM compatible with the one integrated on VF610
-  - "fsl,imx8qm-ftm-pwm" for PWM compatible with the one integrated on i.MX8QM
-- reg: Physical base address and length of the controller's registers
-- #pwm-cells: Should be 3. See pwm.yaml 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.
-- big-endian: Boolean property, required if the FTM PWM registers use a big-
-  endian rather than little-endian layout.
-
-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>;
-		big-endian;
-};
