Added support for CS setup and hold times to meet the SRAM spec. In the process noticed that the baud rate was a little high. Changes since v2: * Incorporate fixes per Stefen Agner review, namely moved hard-coded 50ns delays to device tree properties * Fix for baud rate scale value remainders, reported by Andy Shevchenko Changes since v1: * More detail in commit message for clock rate fix Aaron Brice (3): spi: fsl-dspi: Fix clock rate scale values devicetree: spi: fsl-dspi: Add cs-sck delays spi: fsl-dspi: Add ~50ns delay between cs and sck .../devicetree/bindings/spi/spi-fsl-dspi.txt | 8 ++ drivers/spi/spi-fsl-dspi.c | 97 ++++++++++++++++++---- 2 files changed, 89 insertions(+), 16 deletions(-) -- 2.1.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
