1 NXP System Counter Module(sys_ctr)
3 The system counter(sys_ctr) is a programmable system counter which provides
4 a shared time base to Cortex A15, A7, A53, A73, etc. it is intended for use in
5 applications where the counter is always powered and support multiple,
6 unrelated clocks. The compare frame inside can be used for timer purpose.
10 - compatible : should be "nxp,sysctr-timer"
11 - reg : Specifies the base physical address and size of the comapre
12 frame and the counter control, read & compare.
13 - interrupts : should be the first compare frames' interrupt
14 - clocks : Specifies the counter clock.
15 - clock-names: Specifies the clock's name of this module
