arm_pl031
System Real Time Clock (RTC) Drivers for aarch64 based on PL031.
Examples
use arm_pl031::Rtc;
let rtc = unsafe { Rtc::new(0x901_0000 as _) };
let epoch_time = rtc.get_unix_timestamp();
base_addr
needs to be the device virtual address available for mmio, which can be obtained from
the device tree, for example:
/ {
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";
};
