Merge tag 'pinctrl-v5.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control bulk updates from Linus Walleij:
"Core changes:
- New standard enumerator and corresponding device tree bindings for
output impedance pin configuration. (Implemented and used in the
Renesas rzg2l driver.)
- Cleanup of Kconfig and Makefile to be somewhat orderly and
alphabetic.
New drivers:
- Samsung Exynos 7885 pin controller.
- Ocelot LAN966x pin controller.
- Qualcomm SDX65 pin controller.
- Qualcomm SM8450 pin controller.
- Qualcomm PM8019, PM8226 and PM2250 pin controllers.
- NXP/Freescale i.MXRT1050 pin controller.
- Intel Thunder Bay pin controller.
Enhancements:
- Introduction of the string library helper function
"kasprintf_strarray()" and subsequent use in Rockchip, ST and
Armada pin control drivers, as well as the GPIO mockup driver.
- The Ocelot pin controller has been extensively rewritten to use
regmap and other modern kernel infrastructure.
- The Microchip SGPIO driver has been converted to use regmap.
- The SPEAr driver had been converted to use regmap.
- Substantial cleanups and janitorial on the Apple pin control driver
that was merged for v5.16.
- Janitorial to remove of_node assignments in the GPIO portions that
anyway get this handled in the GPIO core.
- Minor cleanups and improvements in several pin controllers"
