H A D | xilinx_spi.c | 09aac75e Sat Jul 28 17:25:35 CDT 2012 Stephan Linz <linz@li-pro.net> spi: microblaze: Adds driver for Xilinx SPI controller This is an improved version of the driver patch original submitted by Graeme Smecher <graeme.smecher@mail.mcgill.ca> The changes are: - remove hard coded Xilinx BSP defines (XPAR_SPI_*) and use CONFIG_SYS_SPI_BASE from config.h instead - add extensive register struct definitions - remove offset calculation for register access and use the new register struct instead - move default SPI controller configuration from spi_setup_slave() to spi_claim_bus() - add spi_set_speed() - insert SPI controller deactivation in spi_release_bus() - protect while loops in spi_xfer() with counter / timeouts - support SPI mode flags: LSB_FIRST, CPHA, CPOL, LOOP Come from: http://patchwork.ozlabs.org/patch/71797/ Signed-off-by: Stephan Linz <linz@li-pro.net> Tested-by: Michal Simek <monstr@monstr.eu>
