Merge tag 'pinctrl-v4.19-1' 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 v4.19:
Core changes:
- Augment pinctrl_generic_add_group() and pinmux_generic_add_function()
to return the selector for the added group/function to the caller
and augment (hopefully) all drivers to handle this
New subdrivers:
- Qualcomm PM8998 and PM8005 are supported in the SPMI pin control
and GPIO driver
- Intel Ice Lake PCH (platform controller hub) support
- NXP (ex Freescale) i.MX8MQ support
- Berlin AS370 support
Improvements to drivers:
- Support interrupts on the Ocelot pin controller
- Add SPI pins to the Uniphier driver
- Define a GPIO compatible per SoC in the Tegra driver
- Push Tegra initialization down in the initlevels
- Support external wakeup interrupts on the Exynos
- Add generic clocks pins to the meson driver
- Add USB and HSCIF pins for some Renesas PFC chips
- Suspend/resume support in the armada-37xx
- Interrupt support for the Actions Semiconductor S900 also known as
"owl"
- Correct the pin ordering in Cedarfork
- Debugfs output for INTF in the mcp23s08 driver
- Avoid divisions in context save/restore in pinctrl-single
The rest is minor bug fixes or cleanups"
