This is the bulk of pin control changes for the v5.7 kernel cycle. 

There are no core changes this time, only driver developments.
 
 - New driver for the Dialog Semiconductor DA9062 Power Management
   Integrated Circuit (PMIC).
 
 - Renesas SH-PFC has improved consistency, with group and
   register checks in the configuration checker.
 
 - New subdriver for the Qualcomm IPQ6018.
 
 - Add the RGMII pin control functionality to Qualcomm IPQ8064.
 
 - Performance and code quality cleanups in the Mediatek
   driver.
 
 - Improve the Broadcom BCM2835 support to cover all the GPIOs
   that exist in it.
 
 - The Allwinner/Sunxi driver properly masks non-wakeup IRQs on
   suspend.
 
 - Add some missing groups and functions to the Ingenic driver.
 
 - Convert some of the Freescale device tree bindings to use the
   new and all improved JSON YAML markup.
 
 - Refactorings and support for the SFIO/GPIO in the Tegra194
   SoC driver.
 
 - Support high impedance mode in the Spreadtrum/Unisoc driver.

* Freescale IMX8MM 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,imx8mm-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
<arch/arm64/boot/dts/freescale/imx8mm-pinfunc.h>. The last integer CONFIG is
the pad setting value like pull-up on this pin. Please refer to i.MX8M Mini
Reference Manual for detailed CONFIG settings.
Examples:
&uart1 {

pinctrl-0 = <&pinctrl_uart1>;

help
The Dialog DA9062 PMIC provides multiple GPIOs that can be muxed for
different functions. This driver bundles a pinctrl driver to select the
function muxing and a GPIO driver to handle the GPIO when the GPIO
function is selected.
Say yes to enable pinctrl and GPIO support for the DA9062 PMIC.
