    inner: NullLock<PL011UartInner>,
}

Representation of the UART.

Fields

inner: NullLock<PL011UartInner>

Implementations

impl PL011Uart

pub const COMPATIBL: &'static str = "BCM PL011 UART"

pub const unsafe fn new(mmio_start_addr: usize) -> Self

Create an instance.

Safety

• The user must ensure to provide a correct MMIO start address.
