Merge tag 'pinctrl-v5.15-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v5.15 kernel cycle, no
core changes at all this time, just driver work!
New drivers:
- New subdriver for Intel Keem Bay (an ARM-based SoC)
- New subdriver for Qualcomm MDM9607 and SM6115
- New subdriver for ST Microelectronics STM32MP135
- New subdriver for Freescale i.MX8ULP ("Ultra Low Power")
- New subdriver for Ingenic X2100
- Support for Qualcomm PMC8180, PMC8180C, SA8155p-adp PMIC GPIO
- Support Samsung Exynos850
- Support Renesas RZ/G2L
Enhancements:
- A major refactoring of the Rockchip driver, breaking part of it out
to a separate GPIO driver in drivers/gpio
- Pin bias support on Renesas r8a77995
- Add SCI pins support to Ingenic JZ4755 and JZ4760
- Mediatek device tree bindings converted to YAML"
