Enumeration Type Documentation

enum pl08x_dma_chan_state

struct pl08x_dma_chan_state - holds the PL08x specific virtual channel states : the channel is idle : the channel has allocated a physical transport channel and is running a transfer on it : the channel has allocated a physical transport channel, but the transfer is currently paused : the channel is waiting for a physical transport channel to become available (only pertains to memcpy channels)
