The counter, compare and capture registers16 are clocked by an asynchronous clock that can remain enabled in low17 power modes. TPM can support global counter bus where one TPM drives18 the counter bus for the others, provided bit width is the same.19 20properties:21 compatible:22 oneOf:23 - const: fsl,imx7ulp-tpm24 - items:25 - const: fsl,imx8ulp-tpm26 - const: fsl,imx7ulp-tpm27 28 reg:29 maxItems: 130 31 interrupts:32 maxItems: 133 34 clocks:35 items:36 - description: SoC TPM ipg clock37 - description: SoC TPM per clock38 39 clock-names:40 items:41 - const: ipg42 - const: per43 44required:45 - compatible46 - reg47 - interrupts48 - clocks49 - clock-names50 51additionalProperties: false52 53examples:54 - |55 #include <dt-bindings/clock/imx7ulp-clock.h>56 #include <dt-bindings/interrupt-controller/arm-gic.h>57 58 timer@40260000 {59 compatible = "fsl,imx7ulp-tpm";60 reg = <0x40260000 0x1000>;61 interrupts = <GIC_SPI 22 IRQ_TYPE_LEVEL_HIGH>;62 clocks = <&scg1 IMX7ULP_CLK_NIC1_BUS_DIV>,63 <&pcc2 IMX7ULP_CLK_LPTPM5>;64 clock-names = "ipg", "per";65 };66
