Merge tag 'pinctrl-v5.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"The most interesting aspect is that we now have initial support for
the Apple pin controller as used in the M1 laptops and the iPhones
which is a step forward for using Linux efficiently on this Apple
silicon.
Core changes:
- Add infrastructure for per-parent interrupt data to support the
Apple pin controller.
New drivers:
- New combined pin control and GPIO driver for the Apple SoC. This is
used in all modern Apple silicon such as the M1 laptops but also in
at least recent iPhone variants.
- New subdriver for the Qualcomm SM6350
- New subdriver for the Qualcomm QCM2290
- New subdriver for the Qualcomm PM6350
- New subdriver for the Uniphier NX1
- New subdriver for the Samsung ExynosAutoV9
- New subdriver for the Mediatek MT7986
- New subdriver for the nVidia Tegra194
Improvements:
- Improve power management in the Mediatek driver.
- Improvements to the Renesas internal consistency checker.
- Convert the Rockchip pin control device tree bindings to YAML.
- Finally convert the Qualcomm PMIC SSBI and SPMI MPP GPIO driver to
use hierarchical interrupts.
- Convert the Qualcomm PMIC MPP device tree bindings to YAML"
