Field Documentation

prep_slave_single

int(* pbl_dma_controller_ops::prep_slave_single) (const struct pbl_dma_controller *ctrl, uint8_t channel, void *buf, size_t len, enum pbl_dma_dir dir)

Start a transfer on a configured channel.

Returns 0 or a negative errno.

slave_config

int(* pbl_dma_controller_ops::slave_config) (const struct pbl_dma_controller *ctrl, const struct pbl_dma_chan *chan, const struct pbl_dma_slave_config *cfg)

Set the peripheral side of a stopped channel up.

Returns 0 or a negative errno.

terminate

int(* pbl_dma_controller_ops::terminate) (const struct pbl_dma_controller *ctrl, uint8_t channel)

Stop a channel.

Returns 0 or a negative errno.

tx_status

int(* pbl_dma_controller_ops::tx_status) (const struct pbl_dma_controller *ctrl, uint8_t channel, size_t *residue)

Read the bytes left of a channel's transfer.

Returns 0 or a negative errno.
