arm_pl031

基于PL031的aarch64系统实时时钟（RTC）驱动程序。

示例

use arm_pl031::Rtc;

let rtc = unsafe { Rtc::new(0x901_0000 as _) };
let epoch_time = rtc.get_unix_timestamp();

base_addr 需要的是可用于mmio的设备虚拟地址，例如可以从设备树中获取

/ {
	interrupt-parent = <0x8002>;
	model = "linux,dummy-virt";
	#size-cells = <0x02>;
	#address-cells = <0x02>;
	compatible = "linux,dummy-virt";

	pl031@9010000 {
		clock-names = "apb_pclk";
		clocks = <0x8000>;
		interrupts = <0x00 0x02 0x04>;
		reg = <0x00 0x9010000 0x00 0x1000>;
		compatible = "arm,pl031\0arm,primecell";
	};

    ...
}
