A recent refactoring to use the func member in struct function_desc

b755521fd6 pinctrl: imx: support SCMI pinctrl protocol for i.MX95 
The generic pinctrl-scmi.c driver could not be used for i.MX95 because
i.MX95 SCMI firmware not supports functions, groups or generic
'Pin Configuration Type and Enumerations' listed in SCMI Specification.

i.MX95 System Control Management Interface(SCMI) firmware only supports
below pin configuration types which are OEM specific types:
    192: PIN MUX
    193: PIN CONF
    194: DAISY ID
    195: DAISY VAL

To Support fsl,pins property together with SCMI OEM protocol, add this

d85e2ccdf1 pinctrl: qcom: sdm670: add pdc wakeirq map 
The PDC was hooked up as a wakeup parent in the DTS in
commit 71f080633d ("arm64: dts: qcom: sdm670: Hook up PDC as
wakeup-parent of TLMM"), but the wakeirq mapping was not defined so it
had no effect. Add the mapping for wakeup interrupts on the PDC to their
corresponding pins.

Configuring a pin IRQ as dual-edge would break it unless the
wakeirq_dual_edge_errata flag is set.

0a2bcac1a2 pinctrl: ralink: mt76x8: fix pinmux function 
The current version of the pinctrl driver has some issues:

1. Duplicated "gpio" pmx function

The common code will add a "gpio" pmx functon to every pin group, so
it's not necessary to define a separate "gpio" pmx function in pin
groups.

2. Duplicated pmx function name

There are some same function name in different pin groups, which will
cause some problems. For example, when we want to use PAD_GPIO0 as
refclk output function, the common clk framework code will search the
entire pin function lists, then return the first one matched, in this
case the matched function list only include the PAD_CO_CLKO pin group
because there are three "refclk" pin function, which is added by
refclk_grp, spi_cs1_grp and gpio_grp.

To solve this problem, a simple way is just add a pingrp refix to
function name like mt7620 pinctrl driver does.

3. Useless "-" or "rsvd" functon

It's really unnecessary to add a reserved pin mux function to the
function lists, because we never use it.

We were not resetting the pointer to the associated gpio_device once
we are done displaying a pin's information.

This meant that once we reached the end of a gpio-range, if there
were pins right after it that did not belong to any known range,
they would be associated with the previous range's gpio device.

This resulted in those pins appearing as <4294966783:old_gdev> instead

db5032981a pinctrl: core: take into account the pins array in pinctrl_pins_show() 
We previously only looked at the 'pin_base' of the pinctrl_gpio_ranges
struct for determining if a pin matched a GPIO number.

This value is present only if the 'pins' array is not NULL,
and is 0 otherwise. This means that GPIO ranges declared using
gpiochip_add_pingroup_range(), thus making use of pins, were always matched
by the pins in the range [0-npins] even if they contained pins in a
completely separate range.

fb73d663b3 dt-bindings: pinctrl: renesas: Document RZ/V2H(P) SoC 
Add documentation for the pin controller found on the Renesas RZ/V2H(P)
(R9A09G057) SoC.  The RZ/V2H PFC varies slightly compared to the RZ/G2L
family:
  - Additional bits need to be set during pinmuxing,
  - The GPIO pin count is different.

Hence, a SoC-specific compatible string, 'renesas,r9a09g057-pinctrl', is
added for the RZ/V2H(P) SoC.

Also, add the 'renesas,output-impedance' property.  The drive strength
settings on RZ/V2H(P) depend on the different power rails coming out from
the PMIC (connected via I2C).  These power rails (required for drive
strength) can be 1.2V, 1.8V, or 3.3V.

Pins are grouped into 4 groups:

Group 1: Impedance
  - 150/75/38/25 ohms (at 3.3V)
  - 130/65/33/22 ohms (at 1.8V)

Group 2: Impedance
  - 50/40/33/25 ohms (at 1.8V)

Group 3: Impedance
  - 150/75/37.5/25 ohms (at 3.3V)
  - 130/65/33/22 ohms (at 1.8V)

Group 4: Impedance
  - 110/55/30/20 ohms (at 1.8V)
  - 150/75/38/25 ohms (at 1.2V)

The 'renesas,output-impedance' property, as documented, can be
[0, 1, 2, 3], these correspond to register bit values that can
be set in the PFC_IOLH_mn register, which adjusts the drive
strength value and is pin-dependent.

As power rail information may not be available very early in the boot
process, the 'renesas,output-impedance' property is added instead of
reusing the 'output-impedance-ohms' property.

Also, allow bias-disable, bias-pull-down and bias-pull-up properties
as these can be used to configure the pins.

On the RZ/G2L SoC, the PFCWE bit controls writing to PFC registers.

undocumented for the PWPR register on RZ/V2H(P) SoC.  To accommodate these
differences across SoC variants, introduce the pwpr_pfc_lock_unlock()

Note, in rzg2l_pinctrl_set_pfc_mode() the pwpr_pfc_lock_unlock(.., false)

now called after PMC read/write this is to keep changes minimal for
