void DwApbUart (const fuchsia_hardware_serial::wire::SerialPortInfo & serial_port_info, fdf::MmioBuffer mmio, zx::interrupt irq, fidl::ClientEnd<fuchsia_hardware_clock::Clock> baud_clock)

Defined at line 46 of file ../../src/devices/serial/drivers/dw-apb-uart/dw-apb-uart.cc

void ~DwApbUart ()

DwApbUart destructor cancels any pending read/write operations and disables the baud clock.

zx_status_t Config (uint32_t baud_rate, uint32_t flags)

Config configures UART line settings (data bits, parity, stop bits) and baud rate.

It maps FIDL configuration flags to the internal driver representations.

zx_status_t Enable (bool enable)

Enable manages the driver lifecycle state. On enable, it obtains the IRQ,

binds the IRQ handler, and starts the hardware. On disable, it stops the

hardware and cancels the IRQ handler.

void GetInfo (fdf::Arena & arena, GetInfoCompleter::Sync & completer)

void Read (fdf::Arena & arena, ReadCompleter::Sync & completer)

Read initiates an asynchronous read operation. We only support one active read

operation at a time.

Defined at line 406 of file ../../src/devices/serial/drivers/dw-apb-uart/dw-apb-uart.cc

void Write (WriteRequestView request, fdf::Arena & arena, WriteCompleter::Sync & completer)

Write initiates an asynchronous write operation. We only support one active write

operation at a time.

void CancelAll (fdf::Arena & arena, CancelAllCompleter::Sync & completer)

CancelAll aborts all pending asynchronous read and write transactions,

completing them with ZX_ERR_CANCELED.
