The sparse patchset should be ok to take. 

The patch "[05/25] sparse: fix function argument test" will need a 
kernel side update as well. I was planning to send it after OPAL is 

As for the DTS patchset, I think you should wait.

The patchset breaks compatibility with the older kernels and, from the 
latest discussions, this is not what we want : older distros on new 
firmware should continue to have sensor support.

This means that the DTS patchset should be doing something else than 
what it proposes. It should add in a seamlessly fashion a new set of 
nodes for the DTS and update the Linux ibmpowernv driver to take them 
into account. 

I will re-work the code in that direction. This should be possible but
the current layout is difficult to extend and manipulate. The main reason 
being that the sensor type, index, and attribute name are encoded in the 
node name.
