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: "igp" 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"; +}; -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
