Merge tag 'pinctrl-v6.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "The two large chunks is the header clean-up from Andy and the Qualcomm
  DT bindings clean-up from Krzysztof. Each which could give rise to
  conflicts, but I haven't seen any.

  The YAML conversions happening around the device tree is the biggest
  item in the series and is the result of Rob Herrings ambition to
  autovalidate these trees against strict schemas and it is paying off
  in lots of bugs found and ever prettier device trees. Sooner or later
  the transition will be complete, Krzysztof is fixing up all of the
  Qualcomm stuff, which is pretty voluminous.

  Core changes:

   - minor but nice and important documentation clean-ups

  New drivers:

   - subdriver for the Qualcomm SDM670 SoC

   - subdriver for the Intel Moorefield SoC

   - trivial support for the NXP Freescale i.MXRT1170 SoC

Andy Shevchenko e9d10adcd4 pinctrl: zynqmp: Add missing header(s)
Do not imply that some of the generic headers may be always included.
Instead, include explicitly what we are direct user of.

While at it, sort headers alphabetically.

Sai Krishna Potthuri 9989bc33c4 Revert "pinctrl: pinctrl-zynqmp: Add support for output-enable and bias-high-impedance"
This reverts commit ad2bea79ef.

On systems with older PMUFW (Xilinx ZynqMP Platform Management Firmware)
using these pinctrl properties can cause system hang because there is
missing feature autodetection.
When this feature is implemented in the PMUFW, support for these two
properties should bring back.

Sai Krishna Potthuri ad2bea79ef pinctrl: pinctrl-zynqmp: Add support for output-enable and bias-high-impedance
Add support to handle 'output-enable' and 'bias-high-impedance'
configurations. As part of the output-enable configuration, ZynqMP pinctrl
driver takes care of removing the pins from tri-state.

Gerhard Engleder 500c77eed0 pinctrl: zynqmp: Revert "Unify pin naming"
This reverts commit 54784ff249.

This patch changes the pin names from "MIO%d" to "MIO-%d", but all dts
in arch/arm64/boot/dts/xilinx still use the old name. As a result my
ZCU104 has no output on serial terminal and is not reachable over
network.

Andy Shevchenko 54784ff249 pinctrl: zynqmp: Unify pin naming
Since we have devm_kasprintf_strarray() helper, which is used in
the rest of pin control drivers, it makes sense to switch this
driver to it. The pin names are not part of any ABI and hence
there will be no regression based on that. Otherwise all generated
pin names will follow the same schema in the pin control subsystem.

It's not necessary to unregister pin controller device registered
with devm_pinctrl_register() and using pinctrl_unregister() leads
to a double free.

Some minor code cleanups and updates which includes
- Mention module name under help in Kconfig.
- Remove extra lines and duplicate Pin range checks.
- Replace 'return ret' with 'return 0' in success path.
- Copyright year update.
- use devm_pinctrl_register() instead pinctrl_register() in probe.
