Merge tag 'pinctrl-v4.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the big bulk of pin control changes for the v4.13 series:

  Core:
   - The documentation is moved over to RST.
   - We now have agreed bindings for enabling input and output buffers
     without actually enabling input and/or output on a pin. We are
     chiseling out some details of pin control electronics.

  New drivers:
   - ZTE ZX
   - Renesas RZA1
   - MIPS Ingenic JZ47xx: also switch over existing drivers in the tree
     to use this pin controller and consolidate earlier spread out code.
   - Microschip MCP23S08: this driver is migrated from the GPIO
     subsystem and totally rewritten to use proper pin control. All
     users are switched over.

  New subdrivers:
   - Renesas R8A7743 and R8A7745.
   - Allwinner Sunxi A83T R_PIO.
   - Marvell MVEBU Armada CP110 and AP806.
   - Intel Cannon Lake PCH.
   - Qualcomm IPQ8074.

  Notable improvements:
   - IRQ support on the Marvell MVEBU Armada 37xx.
   - Meson driver supports HDMI CEC, AO, I2S, SPDIF and PWM.
   - Rockchip driver now supports iomux-route switching for RK3228,
     RK3328 and RK3399.
   - Rockchip A10 and A20 are merged into a single driver.
   - STM32 has improved GPIO support.
   - Samsung Exynos drivers are split per ARMv7 and ARMv8.
   - Marvell MVEBU is converted to use regmap for register access.

  Maintenance:
   - Several Renesas SH-PFC refactorings and updates.
   - Serious code size cut for Mediatek MT7623.
   - Misc janitorial and MAINTAINERS fixes"
