[Gumstix-users] i2c; platform code

[Jonathan B. <jbr...@ea...>]

I am in the unfortunate position of needing to use two i2c devices that
have the same address.  A bit-bang algorithm is available in the
mainline kernel, and there is a "device" available that uses that
algorithm to bitbang PXA GPIOs*.  However, it relies on adding a
platform device to the platform code (see comments in the linked patch).
What is "platform code"?  Where is the gumstix's platform code?  Can I
fake the effect using a loadable module?  Pointers to decent
documentation would be strongly appreciated.

Thanks,
