Makes no difference for the legacy SPI drivers. If they are used, the
only field in this structure which is checked is "chip_select" so
at91_add_device_spi() can configure the pin (GPIO vs A_periph).
What is important is what SPI_DEVNAME is set to in at91rm9200_devices.c.
#if defined(CONFIG_AT91_SPI) || defined(CONFIG_AT91_SPI_MODULE)
/* legacy SPI driver */
#define SPI_DEVNAME "at91_spi"
#elif defined(CONFIG_SPI_AT91) || defined(CONFIG_SPI_AT91_MODULE)
/* SPI bitbanging driver */
#define SPI_DEVNAME "at91_spi"
#elif defined(CONFIG_SPI_ATMEL) || defined(CONFIG_SPI_ATMEL_MODULE)
/* new SPI driver */
#define SPI_DEVNAME "atmel_spi"
And that depends on what SPI driver(s) you have enabled in the
configuration.
Changes since 2.6.19.....
at91_dataflash.c:
- device->flags = MTD_CAP_NORFLASH;
+ device->flags = MTD_WRITEABLE;
at91_spi.c:
asm/arch/at91rm9200_pdc.h replaced with linux/atmel_pdc.h
AT91_PDC_* definitions replaced with ATMEL_PDC_*
