d1cddd6e5e pinctrl: qcom: lpass-lpi: increase MAX_NR_GPIO to 32
Account for more than only 23 GPIOs in LPASS Low Power Island pinctrl
generic driver. The previous value 23 was chosen to satisfy existing
SoC-specific drivers. However SM4250 LPI pinctrl uses more than 23 GPIOs
and its probe routine fails on:

        if (WARN_ON(data->npins > MAX_NR_GPIO))
                return -EINVAL;

with the following message:

bda79f8fb3 pinctrl: cy8c95x0: Update cache modification
In the previous review cycle the regmap cache update code was
questioned since it seems and odd way of using regmap_update_bits().
Thus update the regmap cache modification code to better explain
what it does and why it's done. This is no functional change, but
it's improving code maintainability.

87d084bcbf pinctrl: renesas: rzg2l: Reorganize variable configuration macro
The `PIN_CFG_VARIABLE` macro did not indicate the capabilities of a pin
but served as a flag indicating that the pins of a port have different
capabilities.

To better reflect its purpose, move the `PIN_CFG_VARIABLE` macro beside
`RZG2L_SINGLE_PIN` and rename it to `RZG2L_VARIABLE_CFG`. Additionally,
introduce new macros for packing variable port configurations:
  - `RZG2L_GPIO_PORT_PACK_VARIABLE(n, a)`: Combines `RZG2L_VARIABLE_CFG`
    with `RZG2L_GPIO_PORT_PACK` to handle variable pin configurations
    for a packed port.
  - `RZG2L_GPIO_PORT_SPARSE_PACK_VARIABLE(m, a)`: Combines
    `RZG2L_VARIABLE_CFG` with `RZG2L_GPIO_PORT_SPARSE_PACK` to handle
    variable pin configurations for a sparse port.

Due to the above change the configuration macros have been reorganized
as follows:
- Shift the bit positions of `PIN_CFG_NOGPIO_INT`, `PIN_CFG_NOD`,
  `PIN_CFG_SMT`, `PIN_CFG_ELC`, and `PIN_CFG_IOLH_RZV2H` down by one
  to accommodate the removal of `PIN_CFG_VARIABLE`.

f0cdf878a2 pinctrl: renesas: rzg2l: Adjust bit masks for PIN_CFG_VARIABLE to use BIT(62)
Shift the bit masks for `PIN_CFG_PIN_MAP_MASK` and `PIN_CFG_PIN_REG_MASK`,
to accommodate `PIN_CFG_VARIABLE` using `BIT(62)`.

Previously, these bit masks were placed higher up in the bit range, which
did not leave room for `PIN_CFG_VARIABLE` at `BIT(62)`. By adjusting these
masks, we ensure that `PIN_CFG_VARIABLE` can occupy `BIT(62)` without any
conflicts. The updated masks are now:
- `PIN_CFG_PIN_MAP_MASK`: `GENMASK_ULL(61, 54)` (was `GENMASK_ULL(62, 55)`)
- `PIN_CFG_PIN_REG_MASK`: `GENMASK_ULL(53, 46)` (was `GENMASK_ULL(54, 47)`)

f28cbab9bb pinctrl: zynqmp: Support muxing individual pins
While muxing groups of pins at once can be convenient for large
interfaces, it can also be rigid. This is because the group is set to
all pins which support a particular function, even though not all pins
may be used. For example, the sdhci0 function may be used with a 8-bit
eMMC, 4-bit SD card, or even a 1-bit SD card. In these cases, the extra
pins may be repurposed for other uses, but this is not currently
allowed.

There is not too much point in pin "groups" when there are not actual
pin groups at the hardware level. The pins can all be muxed
individually, so there's no point in adding artificial groups on top.
Just mux the pins like the hardware allows.

To this effect, add a new group for each pin which can be muxed. These
groups are part of each function the pin can be muxed to. We treat group
selectors beyond the number of groups as "pin" groups. To set this up,
we initialize groups before functions, and then create a bitmap of used
pins for each function. These used pins are appended to the function's
list of groups.
