Hello. I am newbie in kernel development. I want to realize chip select decoding function for AT91. And I'm finding the simplest method for it. I have some questions: 1. Why sizes of variables u8 spi_device.mode, u16 spi_master.mode_bits and u32 bad_bits in spi_setup() are different? I've wanted to use variable spi_device.mode for saving cs_dec flag, but I couldn't do it, because spi_device.mode is fully used for other flags. 2. I want to use spi_device.controller_data to pass pointer to GPIO array used for CS pins. If cs_dec flag is set, so I can interpret pointer in spi_device.controller_data as pointer to array of CS pins GPIO, in either case it will be interpreted as one CS pin GPIO. Is it right way?
