| 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>; |
| }; |
