Merge tag 'pinctrl-v4.18-1' 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 v4.18. No core changes this time! Just a calm all-over-the-place drivers, updates and fixes cycle as it seems. New drivers/subdrivers: - Actions Semiconductor S900 driver with more Actions variants for S700, S500 in the pipe. Also generic GPIO support on top of the same driver and IRQ support is in the pipe. - Renesas r8a77470 PFC support. - Renesas r8a77990 PFC support. - Allwinner Sunxi H6 R_PIO support. - Rockchip PX30 support. - Meson Meson8m2 support. - Remove support for the ill-fated Samsung Exynos 5440 SoC. Improvements: - Context save/restore support in pinctrl-single. - External interrupt support for the Mediatek MT7622. - Qualcomm ACPI HID QCOM8002 supported. Fixes: - Fix up suspend/resume support for Exynos 5433. - Fix Strago DMI fixes on the Intel Cherryview" * tag 'pinctrl-v4.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (72 commits) pinctrl: cherryview: limit Strago DMI workarounds to version 1.0 pinctrl: at91-pio4: add missing of_node_put pinctrl: armada-37xx: Fix spurious irq management gpiolib: discourage gpiochip_add_pin[group]_range for DT pinctrls pinctrl: msm: fix gpio-hog related boot issues MAINTAINERS: update entry for Mediatek pin controller pinctrl: mediatek: remove unused fields in struct mtk_eint_hw pinctrl: mediatek: use generic EINT register maps for each SoC pinctrl: mediatek: add EINT support to MT7622 SoC pinctrl: mediatek: refactor EINT related code for all MediaTek pinctrl can fit dt-bindings: pinctrl: add external interrupt support to MT7622 pinctrl pinctrl: freescale: Switch to SPDX identifier pinctrl: samsung: Fix suspend/resume for Exynos5433 GPF1..5 banks pinctrl: sh-pfc: rcar-gen3: Fix grammar in static pin comments pinctrl: sh-pfc: r8a77965: Add I2C pin support pinctrl: sh-pfc: r8a77990: Add EthernetAVB pins, groups and functions pinctrl: sh-pfc: r8a77990: Add I2C{1,2,4,5,6,7} pins, groups and functions pinctrl: sh-pfc: r8a77990: Add SCIF pins, groups and functions pinctrl: sh-pfc: r8a77990: Add bias pinconf support pinctrl: sh-pfc: Initial R8A77990 PFC support ...
