| * 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"; | |
| }; |
