* Designware APB timer
|
|
|
|
Required properties:
|
|
- compatible: One of:
|
|
"snps,dw-apb-timer"
|
|
"snps,dw-apb-timer-sp" <DEPRECATED>
|
|
"snps,dw-apb-timer-osc" <DEPRECATED>
|
|
- reg: physical base address of the controller and length of memory mapped
|
|
region.
|
|
- interrupts: IRQ line for the timer.
|
|
- either clocks+clock-names or clock-frequency properties
|
|
|
|
Optional properties:
|
|
- clocks : list of clock specifiers, corresponding to entries in
|
|
the clock-names property;
|
|
- clock-names : should contain "timer" and "pclk" entries, matching entries
|
|
in the clocks property.
|
|
- clock-frequency: The frequency in HZ of the timer.
|
|
- clock-freq: For backwards compatibility with picoxcell
|
|
|
|
If using the clock specifiers, the pclk clock is optional, as not all
|
|
systems may use one.
|
|
|
|
|
|
Example:
|
|
timer@ffe00000 {
|
|
compatible = "snps,dw-apb-timer";
|
|
interrupts = <0 170 4>;
|
|
reg = <0xffe00000 0x1000>;
|
|
clocks = <&timer_clk>, <&timer_pclk>;
|
|
clock-names = "timer", "pclk";
|
|
};
