7ff4faba63 pinctrl: spacemit: enable config option
Pinctrl is an essential driver for SpacemiT's SoC,
The uart driver requires it, same as sd card driver,
so let's enable it by default for this SoC.

The CONFIG_PINCTRL_SPACEMIT_K1 isn't enabled when using
'make defconfig' to select kernel configuration options.
This result in a broken uart driver where fail at probe()
stage due to no pins found.

0af4c120f5 pinctrl: pinconf-generic: Print unsigned value if a format is registered
Commit 3ba11e684d ("pinctrl: pinconf-generic: print hex value")
unconditionally switched to printing hex values in
pinconf_generic_dump_one(). However, if a dump format is registered for the
dumped pin, the hex value is printed as well. This hex value does not
necessarily correspond 1:1 with the hardware register value (as noted by
commit 3ba11e684d ("pinctrl: pinconf-generic: print hex value")). As a
result, user-facing output may include information like:
output drive strength (0x100 uA).

To address this, check if a dump format is registered for the dumped
property, and print the unsigned value instead when applicable.

3f36bffab9 pinctrl: Use str_enable_disable-like helpers
Replace ternary (condition ? "enable" : "disable") syntax with helpers
from string_choices.h because:
1. Simple function call with one argument is easier to read.  Ternary
   operator has three arguments and with wrapping might lead to quite
   long code.
2. Is slightly shorter thus also easier to read.
3. It brings uniformity in the text - same string.
4. Allows deduping by the linker, which results in a smaller binary
   file.

f31f33dbb3 pinctrl: amd: Take suspend type into consideration which pins are non-wake
Some laptops have pins which are a wake source for S0i3/S3 but which
aren't a wake source for S4/S5 and which cause issues when left unmasked
during hibernation (S4).

For example HP EliteBook 855 G7 has pin #24 that causes instant wakeup
(hibernation failure) if left unmasked (it is a wake source only for
S0i3/S3).
GPIO pin #24 on this platform is likely dedicated to WWAN XMM7360
modem since this pin triggers wake notify to WWAN modem's parent PCIe
port.

Fix this by considering a pin a wake source only if it is marked as one
for the current suspend type (S0i3/S3 vs S4/S5).

Since Z-wake pins only make sense at runtime these were excluded from
both of suspend categories, so pins with only the Z-wake flag set are
effectively treated as non-wake pins.

accabfaae0 pinctrl: renesas: rzg2l: Fix PFC_MASK for RZ/V2H and RZ/G3E
The PFC_MASK value for the PFC_mx registers is currently hardcoded to
0x07, which is correct for SoCs in the RZ/G2L family, but insufficient
for RZ/V2H and RZ/G3E, where the mask value should be 0x0f.  This
discrepancy causes incorrect PFC register configuration on RZ/V2H and
RZ/G3E SoCs.

On RZ/G2L, the PFC_mx bitfields are also 4 bits wide, with bit 4 marked
as reserved.  The reserved bits are documented to read as zero and be
ignored when written.  Updating the PFC_MASK definition from 0x07 to
0x0f ensures compatibility with both SoC families while maintaining
correct behavior on RZ/G2L.

001d7ef8e3 pinctrl: Fix the clean up on pinconf_apply_setting failure
When some client does devm_pinctrl_get() followed by
pinctrl_select_state() that does pinmux first successfully and later
during config setting it sets the wrong drive strenght to the pin due to
which pinconf_apply_setting fails. Currently, on failure during config
setting is implemented as if pinmux has failed for one of the pin but
that does not seem right and need to undo the pinmux for all the pin if
config setting fails.

Current commit does a bit refactor to reuse the code and tries to clean
up mux setting on config setting failure.
