Hi All,

I modified the spi_mpc83xx to work with the device tree using mpc52xx_psc_spi.c
as a guide.
However, the device->dev->platform_data member is NULL (I thought the child
node would provide that).
What am I missing?
I'm trying to create the SPI driver as a loadable module which will be used by
the m25p80 chip driver (drivers/mtd/devices) which also will be a loadable
module. Am I on the right track?

Could you elaborate on this point please? I couldn't find any examples of gpios
defined within SPI nodes.

Thanks again.
