2019-08-27	clocksource/drivers/imx-sysctr: Add internal clock divider handle	Anson Huang	1	-0/+5
	The system counter block guide states that the base clock is internally divided by 3 before use, that means the clock input of system counter defined in DT should be base clock which is normally from OSC, and then internally divided by 3 before use.

2019-06-25	clocksource/drivers/sysctr: Add nxp system counter timer driver support	Bai Ping	1	-0/+145
	The system counter (sys_ctr) is a programmable system counter which provides a shared time base to the Cortex A15, A7, A53 etc cores. It is intended for use in applications where the counter is always powered on and supports multiple, unrelated clocks. The sys_ctr hardware supports: - 56-bit counter width (roll-over time greater than 40 years) - compare frame(64-bit compare value) contains programmable interrupt generation when compare value <= counter value.
