good point, I missed that one.

It's added by the 'Add GPIO support for PM7325' series
(https://patchwork.kernel.org/project/linux-arm-msm/list/?series=481133)

The binding change was acked by Rob and the code by Bjorn, so it can be
expected to land, but it would still be good to mention the dependency
explicitly.
