Merge tag 'pinctrl-v5.7-1' 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 v5.7 kernel cycle.
There are no core changes this time, only driver developments:
- New driver for the Dialog Semiconductor DA9062 Power Management
Integrated Circuit (PMIC).
- Renesas SH-PFC has improved consistency, with group and register
checks in the configuration checker.
- New subdriver for the Qualcomm IPQ6018.
- Add the RGMII pin control functionality to Qualcomm IPQ8064.
- Performance and code quality cleanups in the Mediatek driver.
- Improve the Broadcom BCM2835 support to cover all the GPIOs that
exist in it.
- The Allwinner/Sunxi driver properly masks non-wakeup IRQs on
suspend.
- Add some missing groups and functions to the Ingenic driver.
- Convert some of the Freescale device tree bindings to use the new
and all improved JSON YAML markup.
- Refactorings and support for the SFIO/GPIO in the Tegra194 SoC
driver.
- Support high impedance mode in the Spreadtrum/Unisoc driver"
