Hi
I have used PXA2XX code to implement SPI in IXP4XX. SPI in both of
them is implemented using an SSP controller. My questions are:
- Should I comment my changes in this list, or just in the linux-arm list?
- SSP code for the PXA2XX is placed inside its own arch directories.
Could it be useful to move it into the SPI directories?
Thanks
Miguel Ángel Álvarez

Into what? It's basically a nonstandard SPI interface; so, into the standard interface. (Of course SSP can be used for stuff that's not SPI.

Which is > why I said "eventually". > So... Returning to the main question. I have code for using SSP and SPI in IXP4XX, and it is based in the PXA2XX. The main problem is that I do not want to add whole new files for what is clearly just a modification. However the original code is not accesible because it is in the mach-pxa2xx directories. Which decision should I take so that my changes have greater chances of been accepted? Moving the files of pxa2xx or creating new ones? Or this is just a bad decision and I should not use the code of pxa2xx at all?
