I did do a set of patches to 4.9 for the ixp4xx platform back in March.
However, I could not get the SPI-GPIO interface to the Micrel KS8995 switch
on my MI424WR router operational at all. The SPI device never showed up.
The device worked with the spi-gpio-old driver which has been removed. I
tried setting up the 4.9 kernel support for spi over gpio but nothing I tried
worked out - I could use some help with this. Everything else was working
OK on 4.9
