Merge tag 'pinctrl-v6.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij: "Nothing special, notably a lot of new Qualcomm hardware is supported, a RISC-V reference SoC and then some cleanups both in code and device tree bindings. Core changes: - Add PINCTRL_PINFUNCTION() macro and use it in several drivers New drivers: - New driver for the StarFive JH7110 SoC "sys" and "aon" (always-on) pin controllers. (RISC-V.) - New subdriver for the Qualcomm QDU1000/QRU1000 SoC pin controller - New subdrivers for the Qualcomm SM8550 SoC and LPASS pin controllers - New subdriver for the Qualcomm SA8775P SoC pin controller - New subdriver for the Qualcomm IPQ5332 SoC pin controller - New (trivial) support for Qualcomm PM8550 and PMR735D PMIC pin control - New subdriver for the Mediatek MT7981 SoC pin controller Improvements: - Several cleanups and refactorings to the Intel drivers - Add 4KOhm bias support to the Intel driver - Use the NOIRQ_SYSTEM_SLEEP_PM_OPS for the AT91 driver - Support general purpose clocks in the Qualcomm MSM8226 SoC - Several conversions to use the new I2C .probe_new() call - Massive clean-up of the Qualcomm Device Tree YAML schemas - Add VIN[45] pins, groups and functions to the Renesas r8a77950 SoC driver" * tag 'pinctrl-v6.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (118 commits) pinctrl: qcom: Add support for i2c specific pull feature pinctrl: starfive: Add StarFive JH7110 aon controller driver pinctrl: starfive: Add StarFive JH7110 sys controller driver dt-bindings: pinctrl: Add StarFive JH7110 aon pinctrl dt-bindings: pinctrl: Add StarFive JH7110 sys pinctrl pinctrl: add mt7981 pinctrl driver dt-bindings: pinctrl: add bindings for MT7981 SoC dt-bindings: pinctrl: rockchip,pinctrl: mark gpio sub nodes of pinctrl as deprecated pinctrl: qcom: Introduce IPQ5332 TLMM driver dt-bindings: pinctrl: qcom: add IPQ5332 pinctrl dt-bindings: pinctrl: qcom: lpass-lpi: correct GPIO name pattern pinctrl: qcom: pinctrl-sm8550-lpass-lpi: add SM8550 LPASS dt-bindings: pinctrl: qcom,sm8550-lpass-lpi-pinctrl: add SM8550 LPASS pinctrl: at91: use devm_kasprintf() to avoid potential leaks dt-bindings: pinctrl: qcom: correct gpio-ranges in examples dt-bindings: pinctrl: qcom,msm8994: correct number of GPIOs dt-bindings: pinctrl: qcom,sdx55: correct GPIO name pattern dt-bindings: pinctrl: qcom,msm8953: correct GPIO name pattern dt-bindings: pinctrl: qcom,sm6375: correct GPIO name pattern and example dt-bindings: pinctrl: qcom,msm8909: correct GPIO name pattern and example ...
