-NXP Low Power Timer/Pulse Width Modulation Module (TPM)
-
-The Timer/PWM Module (TPM) supports input capture, output compare,
-and the generation of PWM signals to control electric motor and power
-management applications. The counter, compare and capture registers
-are clocked by an asynchronous clock that can remain enabled in low
-power modes. TPM can support global counter bus where one TPM drives
-the counter bus for the others, provided bit width is the same.
-
-Required properties:
-
-- compatible :	should be "fsl,imx7ulp-tpm"
-- 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: "ipg" and "per".
-
-Example:
-tpm5: tpm@...60000 {
-	compatible = "fsl,imx7ulp-tpm";
-	reg = <0x40260000 0x1000>;
-	interrupts = <GIC_SPI 22 IRQ_TYPE_LEVEL_HIGH>;
-	clocks = <&clks IMX7ULP_CLK_NIC1_BUS_DIV>,
-		 <&clks IMX7ULP_CLK_LPTPM5>;
-	clock-names = "ipg", "per";
-};
