| SPI_NEW_DEVICE(9) | Serial Peripheral Interface (S | SPI_NEW_DEVICE(9) |
NAME¶
spi_new_device - instantiate one new SPI device
SYNOPSIS¶
struct spi_device * spi_new_device(struct spi_master * master, struct spi_board_info * chip);
ARGUMENTS¶
master
Controller to which device is connected
chip
Describes the SPI device
CONTEXT¶
can sleep
DESCRIPTION¶
On typical mainboards, this is purely internal; and it´s not needed after board init creates the hard-wired devices. Some development platforms may not be able to use spi_register_board_info though, and this is exported so that for example a USB or parport based adapter driver could add devices (which it would learn about out-of-band).
Returns the new device, or NULL.
