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"

The datasheet does not document any registers to control drive strength,
and no drive strength registers are for this reason described for this
SoC. The flags indicating that drive strength can be controlled are
however set for some pins in the driver.
This leads to a NULL pointer dereference when the sh-pfc core tries to
access the struct describing the drive strength registers, for example
when reading the sysfs file pinconf-pins.
Fix this by removing the SH_PFC_PIN_CFG_DRIVE_STRENGTH from all pins.

The comment block explaining the rationale for static pins contains
grammar errors. It appeared first in the pin control driver for R-Car
H3 ES1.x, and spread to R-Car M3-W, H3 ES2.0, and M3-N later.
Fix the grammar in all copies at once.

Note that technically TX_ER is an optional signal in the MII bus, and
thus could have its own group, but this is currently not supported by

Most pins on the R8A77965 SoC can be configured in GPIO mode for
interrupt and GPIO functionality, while a couple of them can also
be routed to the INTC-EX hardware block (formerly known as IRQC).
On R8A77965 the INTC-EX hardware handles pins IRQ0 -> IRQ5 and
this patch adds support for them to the PFC driver as "intc_ex_irqN".
