e4e1718672 Merge patch series "Introduce Intel Tangier pinctrl driver"
Raag Jadav <raag.jadav@intel.com> says:

Merrifield and Moorefield pinctrl driver implementations are similar
in terms of how they access the hardware. We can consolidate their
pinctrl functionalities into a common library driver.

This patch set introduces:

1. Intel Tangier driver that supports the common pinctrl functionalities
   for Merrifield and Moorefield platforms.

2. Intel Tangier adaptation for Merrifield pinctrl driver.

3. Intel Tangier adaptation for Moorefield pinctrl driver.

Tested on Intel Edison platform.
No deviation observed in the contents of below entries before and after
this patchset.

9757300d27 pinctrl: qcom: Add intr_target_width field to support increased number of interrupt targets
SA8775 and newer target have added support for an increased number of
interrupt targets. To implement this change, the intr_target field, which
is used to configure the interrupt target in the interrupt configuration
register is increased from 3 bits to 4 bits.

In accordance to these updates, a new intr_target_width member is
introduced in msm_pingroup structure. This member stores the value of
width of intr_target field in the interrupt configuration register. This
value is used to dynamically calculate and generate mask for setting the
intr_target field. By default, this mask is set to 3 bit wide, to ensure
backward compatibility with the older targets.

Most of the time pin number is equal to pin index in array. So the first

Add support to handle 'output-enable' and 'bias-high-impedance'

Commit 9989bc33c4894e075167 ("Revert "pinctrl: pinctrl-zynqmp: Add support

Support for configuring these properties added in PMUFW Configuration Set
version 2.0. When there is a request for these configurations from pinctrl
driver for ZynqMP platform, xilinx firmware driver checks for this version
before configuring these properties to avoid the hang issue and proceeds
further only when firmware version is >=2 otherwise it returns error.

   - calls clk_prepare_enable() and registers what is needed in order to

This simplifies the code and avoids the need of a dedicated function used

While at it, use dev_err_probe() which filters -EPROBE_DEFER.

060f03e954 pinctrl: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

99084881de pinctrl: cy8c95x0: Add reset support
This patch adds support for an optional "reset" GPIO pin in the cy8c95x0
pinctrl driver. On probe, the reset pin is pulled low to bring chip out
of reset. The reset pin has an internal pull-down and can be left
floating if not required.

The datasheet doesn't mention any timing related to the reset pin.

Based on empirical tests, it was found that the chip requires a
delay of 250 milliseconds before accepting I2C transfers after driving
the reset pin low. Therefore, a delay of 250ms is added before
proceeding with I2C transfers.

635a750d95 pinctrl: amd: Use amd_pinconf_set() for all config options
On ASUS TUF A16 it is reported that the ITE5570 ACPI device connected to
GPIO 7 is causing an interrupt storm.  This issue doesn't happen on
Windows.

Comparing the GPIO register configuration between Windows and Linux
bit 20 has been configured as a pull up on Windows, but not on Linux.
Checking GPIO declaration from the firmware it is clear it *should* have
been a pull up on Linux as well.

```
GpioInt (Level, ActiveLow, Exclusive, PullUp, 0x0000,
	 "\\_SB.GPIO", 0x00, ResourceConsumer, ,)
{   // Pin list
0x0007
}
```

On Linux amd_gpio_set_config() is currently only used for programming
the debounce. Actually the GPIO core calls it with all the arguments
that are supported by a GPIO, pinctrl-amd just responds `-ENOTSUPP`.

To solve this issue expand amd_gpio_set_config() to support the other
arguments amd_pinconf_set() supports, namely `PIN_CONFIG_BIAS_PULL_DOWN`,
`PIN_CONFIG_BIAS_PULL_UP`, and `PIN_CONFIG_DRIVE_STRENGTH`.

bfc374a145 pinctrl: renesas: rzg2l: Handle non-unique subnode names
Currently, sd1 and sd0 have unique subnode names 'sd1_mux' and 'sd0_mux'.
If we change these to non-unique subnode names such as 'mux' this can
lead to the below conflict as the RZ/G2L pin control driver considers
only the names of the subnodes.

   pinctrl-rzg2l 11030000.pinctrl: pin P47_0 already requested by 11c00000.mmc; cannot claim for 11c10000.mmc

Fix this by constructing unique names from the node names of both the
