NXP System Counter Module(sys_ctr)
|
|
|
|
The system counter(sys_ctr) is a programmable system counter which provides
|
|
a shared time base to Cortex A15, A7, A53, A73, etc. it is intended for use in
|
|
applications where the counter is always powered and support multiple,
|
|
unrelated clocks. The compare frame inside can be used for timer purpose.
|
|
|
|
Required properties:
|
|
|
|
- compatible : should be "nxp,sysctr-timer"
|
|
- reg : Specifies the base physical address and size of the comapre
|
|
frame and the counter control, read & compare.
|
|
- interrupts : should be the first compare frames' interrupt
|
|
- clocks : Specifies the counter clock.
|
|
- clock-names: Specifies the clock's name of this module
|
|
|
|
Example:
|
|
|
|
system_counter: timer@306a0000 {
|
|
compatible = "nxp,sysctr-timer";
|
|
reg = <0x306a0000 0x20000>;/* system-counter-rd & compare */
|
|
clocks = <&clk_8m>;
|
|
clock-names = "per";
|
|
interrupts = <GIC_SPI 47 IRQ_TYPE_LEVEL_HIGH>;
|
|
};
