I'm not sure separate infrastructure is needed. We support SPI on MPC8xx/82xx/85xx using the standard I2C infrastructure. I only had to add a couple of IOCTLs to control clock frequency and polarity. Due to such an implementation, lm-sensors work OK with SPI temperature sensors, for example. -- ======================================================================== Yuli Barcohen | Phone +972-9-765-1788 | Software Project Leader yuli@arabellasw.com | Fax +972-9-765-7494 | Arabella Software, Israel ========================================================================
