Kevin O'Connor	c3efcd9c8d	bus: Set all SPI CS pins high before first config_spi message If an SPI device is shared among many devices, then all the device's CS pins should be set high prior to setting up the clk pin. (Otherwise, there's a chance a device could interpret the clk pin setup as part of a transmission.) Signed-off-by: Kevin O'Connor <kevin@koconnor.net>	2019-01-04 22:26:34 -05:00
