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"
