This is the bulk of pin control changes for the v5.12 kernel. 

This time a calm set with no core changes.
 
 New drivers/subdrivers:
 
 - Renesas R8A7790A0 pin controller.
 
 - Allwinner H616 and H616-R pin controllers.
 
 - Qualcomm SM8350 and SC8180x pin controllers.
 
 Improvements:
 
 - Redo the DT bindings for Ralink RT2880.
 
 - A common Qualcomm TLMM DT binding in YAML.
 
 - Delete the unused drivers for U300, COH901, Sirf Atlas, and ZTE ZX.

Please refer to pinctrl-bindings.txt in this directory for details of the common

SiRFatlas7's pinmux nodes act as a container for an arbitrary number of subnodes.
Each of these subnodes represents some desired configuration for a group of pins.
Required subnode-properties:
- groups : An array of strings. Each string contains the name of a group.
- function: A string containing the name of the function to mux to the
group.
Valid values for group and function names can be found from looking at the
group and function arrays in driver files:
drivers/pinctrl/pinctrl-sirf.c
For example, pinctrl might have subnodes like the following:
sd0_pmx: sd0@0 {
sd0 {
groups = "sd0_grp";
function = "sd0";
};
};
sd1_pmx0: sd1@0 {
sd1 {
groups = "sd1_grp0";
function = "sd1_m0";
};
};
sd1_pmx1: sd1@1 {
sd1 {
groups = "sd1_grp1";
function = "sd1_m1";
};
};
For a specific board, if it wants to use sd1,
it can add the following to its board-specific .dts file.
sd1: sd@12340000 {
pinctrl-names = "default";
pinctrl-0 = <&sd1_pmx0>;
}
or
sd1: sd@12340000 {
pinctrl-names = "default";
pinctrl-0 = <&sd1_pmx1>;

* ZTE ZX Pin Controller
The pin controller on ZTE ZX platforms is kinda of hybrid. It consists of
a main controller and an auxiliary one. For example, on ZX296718 SoC, the
main controller is TOP_PMM and the auxiliary one is AON_IOCFG. Both
controllers work together to control pin multiplexing and configuration in
the way illustrated as below.
GMII_RXD3 ---+

DVI1_HS ---+----------------------------- GMII_RXD3 (TOP pin)

BGPIO16 ---+ ^

| AGPIO10 ---+------ KEY_ROW2 (AON pin)
I2S0_DOUT3 ---+ |
|-----------------------+
PWM_OUT3 ---+
|
VGA_VS1 ---+
For most of pins like GMII_RXD3 in the figure, the pinmux function is
controlled by TOP_PMM block only, and this type of pins are meant by term
'TOP pins'. For pins like KEY_ROW2, the pinmux is controlled by both
TOP_PMM and AON_IOCFG blocks, as the available multiplexing functions for
the pin spread in both controllers. This type of pins are called 'AON pins'.
Though pinmux implementation is quite different, pinconf is same for both
types of pins. Both are controlled by auxiliary controller, i.e. AON_IOCFG
on ZX296718.
Required properties:
- compatible: should be "zte,zx296718-pmm".
- reg: the register physical address and length.
- zte,auxiliary-controller: phandle to the auxiliary pin controller which
implements pinmux for AON pins and pinconf for all pins.
The following pin configuration are supported. Please refer to
pinctrl-bindings.txt in this directory for more details of the common
pinctrl bindings used by client devices.
- bias-pull-up
- bias-pull-down
- drive-strength
- input-enable
- slew-rate
Examples:
iocfg: pin-controller@119000 {
compatible = "zte,zx296718-iocfg";
reg = <0x119000 0x1000>;
};
pmm: pin-controller@1462000 {
compatible = "zte,zx296718-pmm";
reg = <0x1462000 0x1000>;
zte,auxiliary-controller = <&iocfg>;
};

pins = "KEY_COL1", "KEY_COL2", "KEY_ROW1", "KEY_ROW2";
function = "VGA";
};
