Subject: [PATCH V3 0/7] pinctrl: API rework, pinconfig in mapping table, ...

This is the current set of patches I have outstanding for pinctrl.

NOTE: This series assumes that commit 7d23de2 "pinctrl: resurrect verbose
pinmux-pins" is dropped, since "Show selected function and group in
pinmux-pins debugfs" re-implements it in a way that's compatible with
all the API rework and restructing in this series.

The locking rework change is still under discussion; I haven't seen a
nak/ack since I was asked to move it later in the series and I explained
the difficulties in doing so while maintaining correctness.

The other changes have fixes based on review feedback.

The Tegra30 pinctrl driver fix should be OK to apply out-of-order if you
want. I'd even be happy if you squashed it into the original commit that
added the driver, if you branch doesn't need to be git-stable.

v3:
* Added patch "Show selected function and group in pinmux-pins debugfs".
* Fixed review feedback in "Enhance mapping table to support pin config
  operations".

Stephen Warren (7):
  pinctrl: Fix and simplify locking
  pinctrl: Refactor struct pinctrl handling in core.c vs pinmux.c
  pinctrl: Add usecount to pins for muxing
  pinctrl: API changes to support multiple states per device
  pinctrl: Enhance mapping table to support pin config operations
  pinctrl: Show selected function and group in pinmux-pins debugfs
  pinctrl: fix case of Tegra30's foo_groups[] arrays
