git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "For this kernel cycle I managed an immutable branch for the PEF2256 WAN framer that has some pin control portions. It already landed in your tree through the net pull request but here it is mentioned again. The most interesting is perhaps the Samsung Exynos subdrivers for the Tensor SoC used in Google Pixel 6 and the ExynosAuto subdriver for automotive. Along with the earlier merged Tesla FSD subdriver it shows some of the versatile uses of the Samsung Exynos silicon. It is also used in the latest version of Axis Communications ARTPEC chips so it is a very widely deployed SoC family. We also have the Intel Meteor Lake SoC which I think is for laptops. It's a pretty interesting chip with Xe graphics and integrated PCH. Core changes: - A new PINCTRL_GROUP_DESC() infrastructure macro is added and used in different drivers, generic group description struct group_desc is now used all over the place. New drivers: - New driver for the Texas Instruments TPS6494 Power Management IC. - New driver for the Lantic PEF2256 framer pin multiplexer. This IC has some pins that can be reconfigured in different ways. The actual driver comes on an immutable branch with the net WAN parts, the IC is some latest-and-greatest serial line funnel for e.g. wireless access points. - New subdriver for the Samsung Exynos Auto V920 pin controller, used for automotive applications. - New subdriver for the Samsung "GS101" SoC pin controller, this is the Google "Tensor" SoC used in the Google Pixel 6. - New subdriver for the Intel Meteor Point SoC pin controller. - New subdriver for the Qualcomm SM8650 top level (TLMM) and LPASS pin controllers. - New subdriver for the Qualcomm X1E80100 top level (TLMM) pin controller. - New subdriver for the Qualcomm SM4450 top level (TLMM) pin controller. - The "single" pin controller now supports the Texas Instruments J7200 SoC. Improvements: - Intel has created a new (Intel-)generic pin controller driver that is now used by all contemporary Intel platforms. - Intel is now also making use of some cleanup helpers. - Enble 910 Ohm bias in the Intel Tangier driver. - The Samsung driver now suppors irq_set_affinity() in it's IRQ chip giving support for non wake up external gpio interrupts" * tag 'pinctrl-v6.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (112 commits) pinctrl: samsung: constify iomem pointers pinctrl: cy8c95x0: Cache muxed registers dt-bindings: pinctrl: xilinx: Rename *gpio to *gpio-grp pinctrl: qcom: lpass-lpi: remove duplicated include dt-bindings: pinctrl: qcom: drop common properties and allow wakeup-parent dt-bindings: pinctrl: qcom: drop common properties dt-bindings: pinctrl: qcom,ipq5018-tlmm: use common TLMM bindings dt-bindings: pinctrl: qcom,x1e80100-tlmm: restrict number of interrupts dt-bindings: pinctrl: qcom,sm8650-tlmm: restrict number of interrupts dt-bindings: pinctrl: qcom,sm8550-tlmm: restrict number of interrupts dt-bindings: pinctrl: qcom,sdx75-tlmm: restrict number of interrupts dt-bindings: pinctrl: qcom,sa8775p-tlmm: restrict number of interrupts dt-bindings: pinctrl: qcom,qdu1000-tlmm: restrict number of interrupts dt-bindings: pinctrl: qcom: create common LPASS LPI schema pinctrl: qcom: sm4450: dd SM4450 pinctrl driver dt-bindings: pinctrl: qcom: Add SM4450 pinctrl dt-bindings: pinctrl: qcom,pmic-mpp: clean up example pinctrl: intel: Add Intel Meteor Point pin controller and GPIO support pinctrl: renesas: rzg2l: Add input enable to the Ethernet pins pinctrl: renesas: rzg2l: Add output enable support ...

Convert drivers to use grp member embedded in struct group_desc, because other members will be removed to avoid duplication and desynchronisation of the generic pin group description.

The driver always registers pin configurations in device tree. This can cause some inconvenience to users, as pin configurations in the base device tree cannot be disabled in the device tree overlay, even when the relevant devices are not used.

2023-09-12pinctrl: starfive: jh7110: Fix failure to set irq after CONFIG_PM is enabledHal Feng1-2/+0
The issue was found when we enabled CONFIG_PM and tested edge events using libgpiod. > # gpiomon -r gpiochip0 55 > gpiomon: error waiting for events: Permission denied `gpiomon` will call irq_chip_pm_get() and then call pm_runtime_resume_and_get() if (IS_ENABLED(CONFIG_PM) && sfp->gc.irq.domain->pm_dev). pm_runtime_resume_and_get() will fail if the runtime pm of pinctrl device is disabled. As we expect the pinctrl driver can be always working and never suspend during runtime, unset sfp->gc.irq.domain->pm_dev to make sure pm_runtime_resume_and_get() won't be called when setting irq.

2023-07-20pinctrl: Explicitly include correct DT includesRob Herring3-7/+1
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
