Thanks, C. Changes since last time this was discussed (06/2017) - the "spi-max-frequency" property is now used to cap the results - chips on FMC controllers are also covered Cédric Le Goater (4): mtd: spi-nor: aspeed: use command mode for reads mtd: spi-nor: aspeed: add support for SPI dual IO read mode mtd: spi-nor: aspeed: retrieve the ABH clock frequency mtd: spi-nor: aspeed: introduce optimized settings for fast reads drivers/mtd/spi-nor/aspeed-smc.c | 294 +++++++++++++++++++++++++++++++++++++-- 1 file changed, 281 insertions(+), 13 deletions(-)
