We were having intermittent problems writing to SRAM chip on SPI bus on vf610 SoM. 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 majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
