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.

* Freescale IMX8MQ IOMUX Controller
Please refer to fsl,imx-pinctrl.txt and pinctrl-bindings.txt in this directory
for common binding part and usage.
Required properties:
- compatible: "fsl,imx8mq-iomuxc"
- reg: should contain the base physical address and size of the iomuxc
registers.
Required properties in sub-nodes:
- fsl,pins: each entry consists of 6 integers and represents the mux and config
setting for one pin. The first 5 integers <mux_reg conf_reg input_reg mux_val
input_val> are specified using a PIN_FUNC_ID macro, which can be found in
imx8mq-pinfunc.h under device tree source folder. The last integer CONFIG is
the pad setting value like pull-up on this pin. Please refer to i.MX8M Quad
Reference Manual for detailed CONFIG settings.
Examples:
&uart1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_uart1>;
