[PATCH] SPI: atmel_spi driver
Driver for the Atmel on-chip SPI master controller.
Tested primarily on AVR32/AT32AP7000/ATSTK1000 using mtd_dataflash and the
jffs2 filesystem. Should also work fine on various AT91 ARM-based chips
like AT91SAM926x and AT91RM9200.
Hardware documentation can be found in the AT32AP7000 data sheet, or its
AT91 siblings, which can be downloaded from
http://www.atmel.com/dyn/products/datasheets.asp?family_id=682
