Fixes a regression in the platform data of imx31moboard. Clean up of some old platform data based spi-imx users. Changes from V1: * Collected reviewed bys. * Minor change to coding style in one patch. Changes from V2: * Reverted minor coding change from V2, it was right to begin with * Have imx-spi also honor "num-cs" property * Leak of spi_bitbang on failure needed to be fixed differently * Port to linux-next, which has other changes to spi-imx Trent Piepho (4): spi: imx: GPIO based chip selects should not be required spi: imx: Fix failure path leak on GPIO request error spi: imx: Don't require platform data chipselect array ARM: imx: Update spi_imx platform data to reflect current state arch/arm/mach-imx/mach-mx31_3ds.c | 18 ++---------------- arch/arm/mach-imx/mach-mx31lilly.c | 12 ++---------- arch/arm/mach-imx/mach-mx31lite.c | 16 ++-------------- arch/arm/mach-imx/mach-mx31moboard.c | 17 +++-------------- arch/arm/mach-imx/mach-pcm037_eet.c | 5 +---- drivers/spi/spi-imx.c | 36 ++++++++++++++++++++--------------- include/linux/platform_data/spi-imx.h | 29 ++++++++++++++++------------ 7 files changed, 48 insertions(+), 85 deletions(-) -- 2.14.3 -- To unsubscribe from this list: send the line "unsubscribe linux-spi" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
