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
