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.
