-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".

-NXP System Counter Module(sys_ctr)

-The system counter(sys_ctr) is a programmable system counter which provides

-Required properties:
-
-- compatible :      should be "nxp,sysctr-timer"
