If you're using arch/powerpc, my understanding is that
CONFIG_XILINX_GPIO needs to be enabled as well as having the right info
in the dts file.
I'm using arch/ppc, so excuse my ignorance but what are dts files ?

Hi,
Dts files are not used with arch/ppc.
In arch/ppc, the drivers that are in the system depend on the

addresses of the devices and their configuration.
I looked at the ML405 setup in the git tree and it appears that it would

This is mpc832x-like MMC setup, but with a quirk to work around PIXIS'

Probably someday we'll want to convert spi_mpc83xx driver into OF driver

Some boards do not use interrupts on the CD line, so we want to poll

On machines with more than one exception level any system register that
might be modified by the "normal" exception level needs to be saved and
restored on taking a higher level exception. We already are saving

For debug level add CSRR0/1

Currently, 'modalias' in the spi_device structure is a 'const char *'.

spi_new_device() allocates and registers an spi device all in one swoop.
If the driver needs to add extra data to the spi_device before it is
