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.
