Hi all,

This is just a bait for further discussion of OF/SPI, chip-selects,

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).
