So, idea V2: 1) Separate out common parts from struct spi_master 2) Create struct spi_slave 2a) Implement spi_slave_send_message for spi_slave 2b) Implement <?> netlink interface to push and pull messages to/from userland ? The protocol won't be done in kernel, but completely in userland. Is this good approach to take? Or maybe 2b can be replaced by blocking read on character device? I think netlink interface might actually be suited quite well for this task.
