struct mipi_dsi_host_ops {
int (* attach) (struct mipi_dsi_host *host,struct mipi_dsi_device *dsi);
int (* detach) (struct mipi_dsi_host *host,struct mipi_dsi_device *dsi);

attach DSI device to DSI host


detach DSI device from DSI host


transmit a DSI packet


DSI packets transmitted by .transfer are passed in as mipi_dsi_msg structures. This structure contains information about the type of packet being transmitted as well as the transmit and receive buffers. When an error is encountered during transmission, this function will return a negative error code. On success it shall return the number of bytes transmitted for write packets or the number of bytes received for read packets.

Note that typically DSI packet transmission is atomic, so the .transfer function will seldomly return anything other than the number of bytes contained in the transmit buffer on success.
