This patchset proposes a solution to describing the valid pins for a pin controller in a semi-generic way so that qcom platforms can expose the pins that are really available. Typically, this has been done by having drivers and firmware descriptions only use pins they know they have access to, and that still works now because we no longer read the pin direction at boot. But there are still some userspace drivers and debugfs facilities that don't know what pins are available and attempt to read everything they can. On qcom platforms, this may lead to a system hang, which isn't very nice behavior, even if root is the only user that can trigger it.
Any progress on this patch set? Stephen no longer works for Qualcomm, so I don't know what the next step is, and I really want this feature in 4.17 (we've missed so many merge windows already).
