283c5ce7da pinctrl: amd: Unify debounce handling into amd_pinconf_set()
Debounce handling is done in two different entry points in the driver.
Unify this to make sure that it's always handled the same.

3f62312d04 pinctrl: amd: Drop pull up select configuration
pinctrl-amd currently tries to program bit 19 of all GPIOs to select
either a 4kΩ or 8hΩ pull up, but this isn't what bit 19 does.  Bit
19 is marked as reserved, even in the latest platforms documentation.

Drop this programming functionality.

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
   pinctrl-rzg2l 11030000.pinctrl: pin-376 (11c10000.mmc) status -22
   pinctrl-rzg2l 11030000.pinctrl: could not request pin 376 (P47_0) from group mux  on device pinctrl-rzg2l
   renesas_sdhi_internal_dmac 11c10000.mmc: Error applying setting, reverse things back

Fix this by constructing unique names from the node names of both the
pin control configuration node and its child node, where appropriate.

Based on the work done by Geert for the RZ/V2M pinctrl driver.

f46a0b47cc pinctrl: renesas: rzv2m: Handle non-unique subnode names
The eMMC and SDHI pin control configuration nodes in DT have subnodes
with the same names ("data" and "ctrl").  As the RZ/V2M pin control
driver considers only the names of the subnodes, this leads to
conflicts:

    pinctrl-rzv2m b6250000.pinctrl: pin P8_2 already requested by 85000000.mmc; cannot claim for 85020000.mmc

Pull new ARM SoC support from Arnd Bergmann:
 "There are two new SoC families this time, and both appear fairly
  similar: The Nuvoton MA35D1 and the STMicroelectronics STM32MP2 are
  both dual-core Cortex-A35 based chips for the low-power industrial
  embedded market, and they mark the first 64-bit product in a widely
  used family of 32-bit Arm MCUs and SoCs.

  The way into the kernel is completely different here: The team at ST
  has a long history of working upstream with their STM32MP1 and other
  SoCs, and they produced a complete port to arm64 together with the
  initial announcement. Nuvoton also has multiple SoC product lines with
  current or previous upstream support, but those are maintained by
  third parties and are unrelated. The patch series from Nuvoton's Jacky
  Huang had to go through many revisisions to get to this point and is
  still missing a few drivers including the serial port for the moment.

  The branch contains the devicetree files as well as all the code
  changes, in order to have something that can be tested standalone"

40ed50cc3d pinctrl: mlxbf3: remove broken Kconfig 'select'
The new pinctrl driver selects GPIO_MLXBF3, but that can not be enabled yet because
the MELLANOX_PLATFORM symbol does not exist in the tree:

WARNING: unmet direct dependencies detected for GPIO_MLXBF3
  Depends on [n]: GPIOLIB [=y] && PCI [=n] && (MELLANOX_PLATFORM [=n] && ARM64 [=y] || COMPILE_TEST [=y])
  Selected by [y]:
  - PINCTRL_MLXBF3 [=y] && PINCTRL [=y] && (MELLANOX_PLATFORM [=n] && ARM64 [=y] || COMPILE_TEST [=y])

As it turns out, the pinctlr driver still builds fine without this, so just
remove the select statement.

1) it explicitly terminates the string which is not needed;
2) it might provoke additional faults, because asked lenght might be

3) it consumes more than needed lines in the source.

Instead of using kmalloc() + strncpy_from_user() + terminating, just
