Actually, spi_device set spi_delay for cs_timing is enough, and about how to set cs_timing, just put it one the master driver. We have test this patch in mediatek platform, it can compeletly meets our needs. Changed in v2: - fix tegra spi build err Changed in v3: - merged patch2/3/4 for build pass Mason Zhang (2): spi: move cs spi_delay to spi_device spi: modify set_cs_timing parameter drivers/spi/spi-mt65xx.c | 107 +++++++++++++++++++++---------------- drivers/spi/spi-tegra114.c | 8 +-- drivers/spi/spi.c | 6 +-- include/linux/spi/spi.h | 23 ++++---- 4 files changed, 78 insertions(+), 66 deletions(-) -- 2.18.0 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
