Recent Intel SoCs share a pinctrl mechanism with many common elements. Add
an implementation of this core functionality, allowing SoC-specific
drivers to avoid adding common code.
As well as a pinctrl driver this provides a GPIO driver based on the same
code.
Once other SoCs use this driver we may consider moving more properties to
the device tree (e.g. the community info and pad definitions).

In the Linux pinctrl binding, the pin configuration nodes don't need to
be direct children of the pin controller device (may be grandchildren for
example). This behavior is managed with the pinconfig u-class which
recursively bind all the sub-node of the pin controller.
But for some binding (when pin configuration is only children of pin
controller) that is not necessary. U-Boot can save memory and reduce
the number of pinconf instance when this feature is deactivated
(for arch stm32mp for example for SPL).
This patch allows to control this feature with a new option
CONFIG_PINCONF_RECURSIVE when it is possible for each individual
pin controller device.

This driver supports the pin and gpio controller found in the Ocelot and

The driver was inspired from the pinctrl driver in Linux, but was
simplified and was modified to allow supporting an other SoCs (Luton).
For Ocelot and Luton the controller is the same, only the pins to program

This patch adds pinctrl support for MT7629 SoC. The IO core found on
the SoC has the registers for pinctrl, pinconf and gpio mixed up in
the same register range. Hence the driver also implements the gpio
functionality through UCLASS_GPIO.
This also creates a common file as there might be other chips that use
the same binding and driver, then being a little more abstract could
help in the long run.

The bcm283x family of SoCs have a GPIO controller that also acts as
pinctrl controller.
This patch introduces a new pinctrl driver that can actually properly mux
devices into their device tree defined pin states and is now the primary
owner of the gpio device. The previous GPIO driver gets moved into a
subdevice of the pinctrl driver, bound to the same OF node.
That way whenever a device asks for pinctrl support, it gets it
automatically from the pinctrl driver and GPIO support is still available
in the normal command line phase.

Add PFC pincontrol driver for the Renesas RCar Gen3 R8A7795 and R8A7796
SoCs. This driver uses the PFC pin tables from Linux, thus letting us
share the occassional fixes to those tables. This driver also has a DT

in board file.
This driver is meant to replace the pinmux part of SH_GPIO_PFC driver.

Not all pins are supported by the driver at the moment, so it actually

in the future would be easier to maintain separately.

This originally started out as
"pinctrl: Kconfig: reorder to keep Rockchip options together"
and tried to keep the Rockchip-related config options together.
However, we now rewrite all chip-specific driver selections to start
with CONFIG_PINCTRL_ (with the inadvertent changes to related
Makefiles) and sort those alphabetically. And as this already means
touching most of the file, we also reformat the help text to not exceed
80 characters (but make full use of those 80 characters).

Introduce pinctrl for i.MX6
1. pinctrl-imx.c is for common usage. It's used by i.MX6/7.
2. Add PINCTRL_IMX PINCTRL_IMX6 Kconfig entry.
3. To the pinctrl_ops implementation, only set_state is implemented.
To i.MX6/7, the pinctrl dts entry is as following:
&iomuxc {
pinctrl-names = "default";
pinctrl_csi1: csi1grp {
fsl,pins = <
MX6UL_PAD_CSI_MCLK__CSI_MCLK 0x1b088
MX6UL_PAD_CSI_PIXCLK__CSI_PIXCLK 0x1b088
MX6UL_PAD_CSI_VSYNC__CSI_VSYNC 0x1b088
>;
};
[.....]
};
there is no property named function or groups. So pinctrl_generic_set_state
can not be used here.
5. This driver is a simple implementation for i.mx iomux controller,
only parse the fsl,pins property and write value to registers.
6. With DEBUG enabled, we can see log when "i2c bus 0":
"
set_state_simple op missing
imx_pinctrl_set_state: i2c1grp
mux_reg 0x14c, conf_reg 0x3bc, input_reg 0x5d8, mux_mode 0x0, input_val 0x1, config_val 0x4000007f
