Geert Uytterhoeven 48bd5c381c pinctrl: starfive: Make the irqchip immutable
Commit 6c846d026d ("gpio: Don't fiddle with irqchips marked as
immutable") added a warning to indicate if the gpiolib is altering the
internals of irqchips.  Following this change the following warning is
now observed for the starfive driver:

    gpio gpiochip0: (11910000.pinctrl): not an immutable chip, please consider fixing it!

Fix this by making the irqchip in the starfive driver immutable.

When the pin PD13 and PD14 is setting up to uart2 function in dts,
there's an error occurred:
1c20800.pinctrl: unsupported function uart2 on pin PD14

Because 'uart2' is not any one multiplexing option of PD14,
and pinctrl don't know how to configure it.

So change the pin PD14 lvds1 function to uart2.

Geert Uytterhoeven 44778aec5e pinctrl: renesas: rmobile: Mark unused PORTCR bits reserved
The PULMD bits and the SEC bit in the PORTCR register descriptions on
SH/R-Mobile SoCs are either unused or unsupported.  Describe them as
reserved bits using a negative field width value, and drop the
corresponding dummy enum IDs.

This reduces kernel size by 2832 (R-Mobile APE6), 2544 (R-Mobile A1),
and/or 3228 (SH-Mobile AG5) bytes.

Geert Uytterhoeven 6210905586 pinctrl: renesas: Add shorthand for reserved register fields
Currently, reserved register fields must be fully described using dummy
enum IDs (zeroes), one for each possible state (2^bits states).

Add support for describing reserved fields using negative field width
values as shorthands, thus removing the need for dummy values.  Apart
from the obvious size reduction due to the removal of the dummy values,
this will also enable merging adjacent reserved fields into a single
field, reducing the number of fields to describe, and thus kernel size.

Update the checker accordingly.

All fields in the IPSR registers on RZ/G1C have the same width, but the
driver describes them using the PINMUX_CFG_REG_VAR() macro, which
is intended for fields with different widths.  Convert the description
to use the PINMUX_CFG_REG() macro for fixed-width fields instead.

Schspa Shi 3c938cc5ce gpio: use raw spinlock for gpio chip shadowed data
In case of PREEMPT_RT, there is a raw_spinlock -> spinlock dependency
as the lockdep report shows.

__irq_set_handler
  irq_get_desc_buslock
    __irq_get_desc_lock
      raw_spin_lock_irqsave(&desc->lock, *flags);  // raw spinlock get here
  __irq_do_set_handler
    mask_ack_irq
      dwapb_irq_ack
        spin_lock_irqsave(&gc->bgpio_lock, flags); // sleep able spinlock
  irq_put_desc_busunlock

Replace with a raw lock to avoid BUGs. This lock is only used to access
registers, and It's safe to replace with the raw lock without bad
influence.

Marek Vasut 05d8af449d pinctrl: stm32: Keep pinctrl block clock enabled when LEVEL IRQ requested
The current EOI handler for LEVEL triggered interrupts calls clk_enable(),
register IO, clk_disable(). The clock manipulation requires locking which
happens with IRQs disabled in clk_enable_lock(). Instead of turning the
clock on and off all the time, enable the clock in case LEVEL interrupt is
requested and keep the clock enabled until all LEVEL interrupts are freed.
The LEVEL interrupts are an exception on this platform and seldom used, so
this does not affect the common case.

This simplifies the LEVEL interrupt handling considerably and also fixes
the following splat found when using preempt-rt:

As seen on any other pinctrl subdriver that calls code from a main driver,
each subdriver needs to have a different compatible string. We don't want
the same compatible string to match a different subdriver's pinmux data as
it's not for our SoC.

Therefore, add new compatible strings for each pinctrl subdriver. Change

Paul Cercueil 8d2d607c6c pinctrl: ingenic: Garbage-collect code paths for SoCs disabled by config
By being a bit smarter about how the SoC version checks are performed,
it is possible to have all the code paths that correspond to SoCs
disabled in the kernel config automatically marked as dead code by the
compiler, and therefore garbage-collected.

With this patch, when compiling a kernel that only targets the JZ4760
for instance, the driver is now about 4.5 KiB smaller.

Krzysztof Kozlowski ac875df4d8 pinctrl: samsung: fix missing GPIOLIB on ARM64 Exynos config
The Samsung pinctrl drivers depend on OF_GPIO, which is part of GPIOLIB.
ARMv7 Exynos platform selects GPIOLIB and Samsung pinctrl drivers. ARMv8
Exynos selects only the latter leading to possible wrong configuration
on ARMv8 build:

  WARNING: unmet direct dependencies detected for PINCTRL_EXYNOS
    Depends on [n]: PINCTRL [=y] && OF_GPIO [=n] && (ARCH_EXYNOS [=y] || ARCH_S5PV210 || COMPILE_TEST [=y])
    Selected by [y]:
    - ARCH_EXYNOS [=y]

Always select the GPIOLIB from the Samsung pinctrl drivers to fix the
issue.  This requires removing of OF_GPIO dependency (to avoid recursive
dependency), so add dependency on OF for COMPILE_TEST cases.

Aidan MacDonald 9279c00fa4 pinctrl: ingenic: Fix regmap on X series SoCs
The X series Ingenic SoCs have a shadow GPIO group which is at a higher
offset than the other groups, and is used for all GPIO configuration.
The regmap did not take this offset into account and set max_register
too low, so the regmap API blocked writes to the shadow group, which
made the pinctrl driver unable to configure any pins.

Fix this by adding regmap access tables to the chip info. The way that
max_register was computed was also off by one, since max_register is an
inclusive bound, not an exclusive bound; this has been fixed.

 is a bit larger again. There are nine new SoC that get added,
 all of them related to existing platforms:

AngeloGioacchino Del Regno 156f721704 pinctrl: mediatek: common-v1: Commonize spec_ies_smt_set callback
All of the MediaTek pinctrl drivers registering with pinctrl-mtk-common
that are offering a .spec_ies_smt_set() callback are declaring their
own function which is doing exactly the same on all drivers: calling
mtk_pconf_spec_set_ies_smt_range() with their struct and a simple check.

Commonize this callback by adding the ies and smt structure pointers
to struct mtk_pinctrl_devdata and changing the callback signature to
take it.

Removing the callback and checking for the existance of the spec_smt
and/or spec_ies data would allow us to staticize the function
mtk_pconf_spec_set_ies_smt_range(), but this solution was avoided as
to keep flexibility, as some SoCs may need to perform a very different
operation compared to what this commonized function is doing.

which is possible to use on all of the pinctrl drivers that are
using the v1 pinctrl-mtk-common code, with the exception of mt8135,
which has a different handling compared to the others.
Since the callback function signature was changed, this had to be
propagated to pinctrl-mt8135's spec_pull_set().

AngeloGioacchino Del Regno c8c206cdc1 pinctrl: mediatek: common-v1: Use common probe function
Most of the mediatek pinctrl drivers are calling mtk_pctrl_init() and
passing only a pointer to struct mtk_pinctrl_devdata, as the regmap
handle it passed from device-tree, with the exception of mt6397.

For all of the drivers that don't require passing a struct regmap
pointer from a parent device, simplify the probe mechanism by assigning
the required structure as match data and use mtk_pctrl_common_probe()
as their probe function.

While at it, also collapse the of_device_id entries to a single line,
as they all fit in max 83 columns, which is acceptable.

Michael Walle 1f3c85c22d pinctrl: microchip-sgpio: wait until output is actually set
Right now, when a gpio value is set, the actual hardware pin gets set
asynchronously. When linux write the output register, it takes some time
until it is actually propagated to the output shift registers. If that
output port is connected to an I2C mux for example, the linux driver
assumes the I2C bus is already switched although it is not.

Fortunately, there is a single shot mode with a feedback: you can
trigger the single shot and the hardware will clear that bit once it has
finished the clocking and strobed the load signal of the shift
registers. This can take a considerable amount of time though.
Measuremens have shown that it takes up to a whole burst cycle gap which
is about 50ms on the largest setting. Therefore, we have to mark the
output bank as sleepable. To avoid unnecessary waiting, just trigger the
single shot if the value was actually changed.

Chen-Yu Tsai e5fabbe43f pinctrl: mediatek: paris: Support generic PIN_CONFIG_DRIVE_STRENGTH_UA
Some of the MediaTek chips that utilize the Paris pinctrl driver library
support a lower drive strength (<= 1mA) than the standard drive strength
settings (2~16 mA) on certain pins. This was previously supported by the
custom MTK_PIN_CONFIG_DRV_ADV parameter along with the
"mediatek,drive-strength-adv" device tree property.

The drive strength values for this hardware are 125, 250, 500, and 1000 mA,
and can be readily described by the existing "drive-strength-microamp"
property, which then gets parsed by the generic pinconf library into the
parameter PIN_CONFIG_DRIVE_STRENGTH_UA.

Add support for PIN_CONFIG_DRIVE_STRENGTH_UA while keeping the old
custom parameter around for backward compatibility.

Chen-Yu Tsai 9b780fa1ff pinctrl: mediatek: paris: Rework mtk_pinconf_{get,set} switch/case logic
The current code deals with optional features by testing for the
function pointers and returning -ENOTSUPP if it is not valid. This is
done for multiple pin config settings and results in the code that
handles the supporting cases to get indented by one level. This is
aggrevated by the fact that some features require another level of
conditionals.

Instead of assigning the same error code in all unsupported optional
feature cases, simply have that error code as the default, and break
out of the switch/case block whenever a feature is unsupported, or an
error is returned. This reduces indentation by one level for the useful
code.

Also replace the goto statements with break statements. The result is
the same, as the gotos simply exit the switch/case block, which can
also be achieved with a break statement. With the latter the intent
is clear and easier to understand.

This driver is based on the one for NPCM7xx, because the WPCM450 is a
predecessor of those SoCs. Notable differences:

- On WPCM450, the GPIO registers are not organized in multiple banks,
  but rather placed continually into the same register block. This
  affects how register offsets are computed.
- Pinmux nodes can explicitly select GPIO mode, whereas in the npcm7xx
  driver, this happens automatically when a GPIO is requested.

Some functionality implemented in the hardware was (for now) left unused
in the driver, specifically blinking and pull-up/down.

Samuel Holland bac129dbc6 pinctrl: sunxi: Use unique lockdep classes for IRQs
This driver, like several others, uses a chained IRQ for each GPIO bank,
and forwards .irq_set_wake to the GPIO bank's upstream IRQ. As a result,
a call to irq_set_irq_wake() needs to lock both the upstream and
downstream irq_desc's. Lockdep considers this to be a possible deadlock
when the irq_desc's share lockdep classes, which they do by default:

 ============================================
 WARNING: possible recursive locking detected

  __do_sys_reboot from ret_fast_syscall+0x0/0x1c

However, this can never deadlock because the upstream and downstream
IRQs are never the same (nor do they even involve the same irqchip).

Silence this erroneous lockdep splat by applying what appears to be the
usual fix of moving the GPIO IRQs to separate lockdep classes.

Arnd Bergmann 4d9b86eb38 Samsung pinctrl DTS and driver changes for v5.18
Conversion of Samsung pinctrl bindings to dtschema followed up with
 alignment of DTS files to the dtschema.
 
 The entire work consists of three parts but everything should be merged
 at once to avoid dtschema check errors:
 1. Samsung pinctrl driver change necessary to accept new DTS (driver
    depends on node names and this has to be adjusted because of dtschema).
 2. Conversion to dtschema which brings requirement of different naming
    of the GPIO nodes.
 3. DTS commits depending on driver (1) above, which convert all GPIO pin
    bank names to new naming, required by dtschema.
    This also includes few cleanups around DTS which are here to avoid
    any merge conflicts.
 
 The Samsung pinctrl driver changes are backwards compatible.  However
 the DTS changes (renaming nodes) could cause problems in out-of-tree or
 other project implementations of the driver.

Increase SH_PFC_MAX_ENUMS accordingly, now more enum IDs are checked
