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
Other changes and improvements
- major clean-up of the Qualcomm pin control device tree bindings by
Krzysztof
- major header clean-up by Andy
- some immutable irqchip clean-up for the Actions Semiconductor and
Nuvoton drivers
- GPIO helpers for The Cypress cy8c95x0 driver
- bias handling in the Mediatek MT7986 driver
- remove the unused pins-are-numbered concept that never flew"
