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"
