I had a very similar update a while back, which clearly I never got around to submitting. Can't find it just now. I think also that spi-gpio needs to be fairly close to a reference implementation for SPI-on-Linux, and this helps achieve that semantic goal. > There are some boards that do not > strictly follow SPI standard and use > only 3 wires (SCLK, MOSI or MISO, SS) for connecting some simple auxiliary > chips Since SPI is a de-facto standard, it's routine to have variances like (half duplex signaling in some chips, and special SS/CS handling.
