Hi all, I was working on a p2041rdb target not so long ago and needed to use the gpio pins (described in detail in the p2041 reference manual), these are visible on the p2041 fact sheet [1]. The pins are connected to a gpio expander, PCA9672 [2], which is connected to an i2c-bus.
The expander was not available in the device-tree for p2041rdb so I patched it locally to include it. The gpio-expander does not seem to be available in any upstream repository either (at this time I was working on a version of the 3.12 kernel). Would this patch be of any interest for meta-fsl-ppc? The gpio pins are there on all p2041rdb targets (at least since they are mentioned as such in the reference guide), so I could not come up with a reason to why it is excluded from the device tree.
