class SpiRequest

Defined at line 50 of file ../../src/devices/spi/drivers/aml-spi/aml-spi.h

SpiRequest represents a fuchsia.hardware.spiimpl.SpiImpl request that may be completed

asynchronously. Requests that operate on registered VMOs take a chip select value and completer

callback, while requests that involve a data transfer additionally take a start completer and

TX/RX data buffers.

Public Methods

void SpiRequest (uint32_t chip_select, Buffer tx_buffer, Buffer rx_buffer, StartCallback start, CompleteCallback complete)

Constructor for data transfer requests.
