2013-09-12spi: fix return value check in dspi_probe()Wei Yongjun1-8/+2
In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-08-22spi:Add Freescale DSPI driver for Vybrid VF610 platformChao Fu1-0/+557
The serial peripheral interface (SPI) module implemented on Freescale Vybrid platform provides a synchronous serial bus for communication between Vybrid and the external peripheral device. The SPI supports full-duplex, three-wire synchronous transfer, has TX/RX FIFO with depth of four entries. This driver is the SPI master mode driver and has been tested on Vybrid VF610TWR board.
