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" * tag 'pinctrl-v5.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (64 commits) pinctrl: qcom: fix compilation error pinctrl: qcom: use scm_call to route GPIO irq to Apps pinctrl: sprd: Add pin high impedance mode support pinctrl: sprd: Use the correct pin output configuration pinctrl: tegra: Add SFIO/GPIO programming on Tegra194 pinctrl: tegra: Renumber the GG.0 and GG.1 pins pinctrl: tegra: Do not add default pin range on Tegra194 pinctrl: tegra: Pass struct tegra_pmx for pin range check pinctrl: tegra: Fix "Scmitt" -> "Schmitt" typo pinctrl: tegra: Fix whitespace issues for improved readability pinctrl: mediatek: Use scnprintf() for avoiding potential buffer overflow pinctrl: freescale: drop the dependency on ARM64 for i.MX8M Revert "pinctrl: mvebu: armada-37xx: use use platform api" dt-bindings: pinctrl: at91: Fix a typo ("descibe") pinctrl: meson: add tsin pinctrl for meson gxbb/gxl/gxm pinctrl: sprd: Fix the kconfig warning pinctrl: ingenic: add hdmi-ddc pin control group pinctrl: sirf/atlas7: Replace zero-length array with flexible-array member pinctrl: sprd: Allow the SPRD pinctrl driver building into a module pinctrl: Export some needed symbols at module load time ...
