Merge tag 'pinctrl-v5.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij: "This is a calm cycle, not much happened this time around: not even much incremental development. Some three new drivers, that is all. No core changes. New drivers: - NXP (ex Freescale) i.MX 8QM driver. - NXP (ex Freescale) i.MX 8MM driver. - AT91 SAM9X60 subdriver. Improvements: - Support for external interrups (EINT) on Mediatek virtual GPIOs. - Make BCM2835 pin config fully generic. - Lots of Renesas SH-PFC incremental improvements" * tag 'pinctrl-v5.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (70 commits) pinctrl: imx: fix scu link errors dt-bindings: pinctrl: Document the i.MX50 IOMUXC binding pinctrl: qcom: spmi-gpio: Reorder debug print pinctrl: nomadik: fix possible object reference leak pinctrl: stm32: return error upon hwspinlock failure pinctrl: stm32: fix memory leak issue pinctrl: sh-pfc: r8a77965: Add DRIF pins, groups and functions pinctrl: sh-pfc: r8a77965: Add TMU pins, groups and functions pinctrl: sh-pfc: Validate fixed-size field widths at build time pinctrl: sh-pfc: sh73a0: Fix fsic_spdif pin groups pinctrl: sh-pfc: r8a7792: Fix vin1_data18_b pin group pinctrl: sh-pfc: r8a7791: Fix scifb2_data_c pin group pinctrl: sh-pfc: emev2: Add missing pinmux functions pinctrl: sunxi: Support I/O bias voltage setting on A80 pinctrl: ingenic: Add LCD pins for the JZ4725B SoC pinctrl: samsung: Remove legacy API for handling external wakeup interrupts mask pinctrl: bcm2835: Direct GPIO config changes to generic pinctrl pinctrl: bcm2835: declare pin config as generic pinctrl: qcom: qcs404: Drop unused UFS_RESET macro dt-bindings: add documentation for slew rate ...
