Struct GPIO

pub struct GPIO {
    inner: NullLock<GPIOInner>,
}

Representation of the GPIO HW.

Fields

inner: NullLock<GPIOInner>

Implementations

impl GPIO

pub const COMPATIBLE: &'static str = "BCM GPIO"

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.

pub fn map_pl011_uart(&self)

Concurrency safe version of GPIOInner.map_pl011_uart()

Trait Implementations

impl DeviceDriver for GPIO

fn compatible(&self) -> &'static str

Return a compatibility string for identifying the driver.

unsafe fn init(&self) -> Result<(), &'static str>

Called by the kernel to bring up the device.
