10
12 master
13 Controller to which device is connected
14
16 can sleep
17
19 Allows a driver to allocate and initialize a spi_device without
20 registering it immediately. This allows a driver to directly fill the
21 spi_device with device parameters before calling spi_add_device on it.
22
23 Caller is responsible to call spi_add_device on the returned spi_device
24 structure to add it to the SPI master. If the caller needs to discard
25 the spi_device without adding it, then it should call spi_dev_put on
26 it.
27
28 Returns a pointer to the new device, or NULL.
