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@40260000 {
|
|
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";
|
|
};
