I've converted the spi_mpc83xx to the OF driver (using Grant's SPI_MASTER_OF work + some additions), and implemented MMC-over-SPI bindings. This stuff extensively using GPIOs, and I think this will work for the "bridged SPI" too, since the SPI bridge could be represented as GPIO controller (inside the SPI controller node). Thoughts? -- Anton Vorontsov email: cbouatmailru@gmail.com irc://irc.freenode.net/bd2
