On modern Renesas SoCs, all PFC registers are 32-bit, and all callers of

Hence make the 32-bit width implicit, and rename the functions to

The Armada 37xx driver always initializes the IRQ base to 0, hence the
subtraction is a no-op. Remove the subtraction and thereby the last user
of struct gpio_chip's .irq_base field.
Note that this was also actually a bug and only worked because of the
above assumption. If the IRQ base had been dynamically allocated, the
subtraction would've caused the wrong mask to be generated since the
struct irq_data.hwirq field is an index local to the IRQ domain. As a
result, it should now be safe to also allocate this chip's IRQ base
dynamically, unless there are consumers left that refer to the IRQs by
their global number.

On Asus laptop models X505BA, X505BP, X542BA and X542BP, the i2c-hid
touchpad (using a GPIO for interrupts) becomes unresponsive after a
few minutes of usage, or after placing two fingers on the touchpad,
which seems to have the effect of queuing up a large amount of input
data to be transferred.
When the touchpad is in unresponsive state, we observed that the GPIO
level-triggered interrupt is still at it's active level, however the
pinctrl-amd driver is not receiving/dispatching more interrupts at this
point.
After the initial interrupt arrives, amd_gpio_irq_mask() is called
however we then see amd_gpio_irq_handler() being called repeatedly for
the same irq; the interrupt mask is not taking effect because of the
following sequence of events:
- amd_gpio_irq_handler fires, reads and caches pin reg
- amd_gpio_irq_handler calls generic_handle_irq()
- During IRQ handling, amd_gpio_irq_mask() is called and modifies pin reg
- amd_gpio_irq_handler clears interrupt by writing cached value
The stale cached value written at the final stage undoes the masking.
Fix this by re-reading the register before clearing the interrupt.
I also spotted that the interrupt-clearing code can race against
amd_gpio_irq_mask() / amd_gpio_irq_unmask(), so add locking there.
Presumably this race was leading to the loss of interrupts.
After these changes, the touchpad appears to be working fine.

if (readl(®s->invert_set) & pintbit)
^~
It seems the driver need to include <asm/gpio.h> and <asm/irq.h>
to compile.
The Blackfin architecture was re-defining the Kconfig
PINCTRL symbol which is not OK, so replaced this with
PINCTRL_BLACKFIN_ADI2 which selects PINCTRL and PINCTRL_ADI2
just like most arches do.
Further, the old GPIO driver symbol GPIO_ADI was possible to
select at the same time as selecting PINCTRL. This was not
working because the arch-local <asm/gpio.h> header contains
an explicit #ifndef PINCTRL clause making compilation break
if you combine them. The same is true for DEBUG_MMRS.
Make sure the ADI2 pinctrl driver is not selected at the same
time as the old GPIO implementation. (This should be converted
to use gpiolib or pincontrol and move to drivers/...) Also make
sure the old GPIO_ADI driver or DEBUG_MMRS is not selected at
the same time as the new PINCTRL implementation, and only make
PINCTRL_ADI2 selectable for the Blackfin families that actually
have it.
This way it is still possible to add e.g. I2C-based pin
control expanders on the Blackfin.

This change prepare the introduction of new meson SoC. This new SoC will
share the same gpio/pinconf registers but the pinmux part will be
different. While the format of the data associated with each pinmux group
will change, the way to handle pinmuxing will be similar.
To deal with this new situation, the meson_pmx_struture is kept but the
data associated to it is now generic. This allows to reuse the basic
functions which would otherwise be copy/pasted in each pinmux driver
(such as getting the name a count of groups and functions) Only the
functions actually using this specific data is taken out of the common
code and is handling the SoC pinmuxing

When meson pinctrl is enabled, all meson platforms pinctrl drivers are

This leads to situation where pinctrl drivers targeting an architecture
are also compiled and shipped on another one (ex: meson8 - ARM - compiled
and shipped on ARM64 builds). This is a waste of memory we can easily
avoid.
This change makes 4 pinctrl drivers (1 per SoC) out the original single

New GPIO IRQs are allocated and mapped dynamically by default when

This causes issues on some Intel platforms [1][2] with broken BIOS which
hardcodes Linux IRQ numbers in their ACPI tables.
On such platforms cherryview-pinctrl driver should allocate and map all
GPIO IRQs at probe time.
Side effect - "Cannot allocate irq_descs @ IRQ%d, assuming pre-allocated\n"
can be seen at boot log.
NOTE. It still may fail if boot sequence will changed and some interrupt
controller will be probed before cherryview-pinctrl which will shift Linux IRQ
numbering (expected with CONFIG_SPARCE_IRQ enabled).

DRIF support for r8a7795 was initially added with commit 2d77583198

The touchpad in the Asus laptop models X505BA/BP and X542BA/BP is
unresponsive after suspend/resume. The following error appears during
resume:
i2c_hid i2c-ELAN1300:00: failed to reset device.
The problem here is that i2c_hid does not notice the interrupt being
generated at this point, because the GPIO is no longer configured
for interrupts.
Fix this by saving pinctrl-amd pin registers during suspend and
restoring them at resume time.
Based on code from pinctrl-intel.

Since commit dc749a09ea ("gpiolib: allow gpio irqchip to map irqs

gpiochip_irqchip_add.

This patch moves the initialization of the mask field in the irq_startup
function. However some callbacks such as irq_set_type and irq_set_wake
could be called before irq_startup. For those functions the mask is
computed at each call which is not a issue as these functions are not
located in a hot path but are used sporadically for configuration.

In some scenarios, we should set some pins as input/output/pullup/pulldown
when the specified system goes into deep sleep mode, then when the system
goes into deep sleep mode, these pins will be set automatically by hardware.
That means some pins are not controlled by any specific driver in the OS, but
need to be controlled when entering sleep mode. Thus we introduce one sleep
state config into pinconf-generic for users to configure.

MT2701 shares the same driver with MT7623, but there is a slight difference
between their pin functions (e.g., PCIe), so we update the different parts
in pinmux table.
Doing so, SoC could choose the correct mux setting via their own pinfun.h.

The pin controller of Allwinner H5 has three IRQ banks, however in old
versions of drivers and device trees, only two are set, which makes
PG bank IRQ not available.
If it's directly set to 3, the old device trees will fail to boot.
Add a workaround (and a warning) for older device trees, and allow new
device trees to use correct 3 IRQ banks.

The fix prevents unintended wakes from second level GPIO pin interrupts.
On some Intel Kabylake platforms, it is observed that GPIO pin interrupts
can wake the platform from suspend-to-idle, even though the IRQ is not
configured as IRQF_NO_SUSPEND or enable_irq_wake().
This can cause undesired wakes on Mobile devices such as Laptops and
Chromebook devices. For example a headset jack insertion is not a desired
wake source on Chromebook devices.
The pinctrl-intel (GPIO controller) driver implements a "Shared IRQ" model.
All GPIO pin interrupts are OR'ed and mapped to a first level IRQ14 (or
IRQ15). The driver registers an irq_chip struct and maps an irq_domain for
the GPIO pin interrupts. The IRQ14 handler demuxes and calls the second
level IRQ for the respective pin.
In the suspend entry flow, at suspend_noirq stage, the kernel disables IRQs
that are not marked for wake. The pinctrl-intel driver does not implement a
irq_disable() callback (to take advantage of lazy disabling). The
pinctrl-intel GPIO interrupts are not disabled in hardware during suspend
entry, and thus are able to wake the SoC out of suspend-to-idle.
This patch sets the IRQCHIP_MASK_ON_SUSPEND flag for the GPIO irq_chip, to
disable the second level interrupts at suspend_noirq stage via the irq_mask
callbacks. The irq_mask callback disables the IRQs in hardware by
programming the corresponding GPIO pad registers. Only IRQs that are not
marked for wake are disabled.

Different PMIC maybe have different pin features, for example,
RK816 has one pin which can be used for TS or GPIO(input/out).
The mainly difference between PMICs pins are pinmux, direction

0x200), which is like A33. However, this is not worked around when
developing the driver, which makes IRQ not working.
Fix the IRQ bank base.

of_irq_get() may return any negative error number as well as 0 on failure,
while the driver only checks for -EPROBE_DEFER, blithely continuing with
the call to gpiochip_set_chained_irqchip() -- that function expects the
parent IRQ as *unsigned int*, so would probably do nothing when a large
IRQ number resulting from a conversion of a negative error number is passed
to it, however passing 0 would probably work but the driver won't receive
valid GPIO bank interrupts.
Check for 'ret <= 0' instead and return -ENXIO from the driver's probe iff
of_irq_get() returned 0.

Implement the AST2400 USB functions as described by the devicetree

through the bindings and pinctrl, though there are remnants of
documentation for a fourth port muxed with GPIO pins GPIOQ6 and GPIOQ7.
The implementation is updated to reflect this but the function and
group are not exposed.
Disregarding the mostly undocumented fourth port, the USB functions are
an outlier with respect to the rest of the muxed functionality on the
AST2400 as GPIO is not supported on these pins.

gpio_request_enable/disable_free actually are not quite necessary as
standard IMX pinctrl binding already sets GPIO mux from device tree,
e.g. VF610_PAD_PTB20__GPIO_42 or MX7D_PAD_SD2_CD_B__GPIO5_IO9
No need to do it again in gpio_request_enable.
And according to Stefan:
"For all GPIO I checked in upstream device trees we assign a pinctrl
to the same node, so in all cases gpio_request_enable/disable is really
unnecessary."
So it should be safe to simply remove it.
Note that this changes semantics for Vybrid, e.g.
"The two functions have been introduced for Vybrid (through
SHARE_MUX_CONF_REG) and mux pins as GPIOs automatically when a GPIO
gets requested. The automatic mux is optional by the pinmux/gpio
subsystem semantics, and other NXP devices do not use it, instead an
explicit pinctrl node is added in the device tree to mux GPIOs where
required. Hence this change aligns Vybrid to other NXP (i.MX) devices.
Note that all upstream device tree assign proper pinctrl properties
where GPIOs are used so no change is necessary for device trees."

The I2C pin functions in R_PIO used to be named "s_twi".
As we usually use the name "i2c" instead of "twi" in the mainline
kernel, change these names to "s_i2c" for consistency.
The "s_twi" functions are not yet referenced by any device trees in
mainline kernel so I think it's safe to change the name.

R40 is said to be an upgrade of A20, and its pin configuration is also
similar to A20 (and thus similar to A10).
Add support for R40 to the A10 pinctrl driver.

GPIO_PULL bits configurations in TLMM_GPIO_CFG register
differs for IPQ40xx from rest of the other qcom SoCs.
As it does not support the keeper state and therefore can't
support bias-bus-hold property.
This patch adds a pull_no_keeper setting which configures the
msm_gpio_pull bits for ipq40xx. This is required to fix the
proper configurations of gpio-pull bits for nand pins mux.
IPQ40xx SoC:
2'b10: Internal pull up enable.
2'b11: Unsupport
For other SoC's:
2'b10: Keeper
2'b11: Pull-Up
Note: Due to pull_no_keeper length, all kerneldoc entries
in the msm_pinctrl_soc_data struct had to be realigned.

Pull pin control fixes from Linus Walleij:
"These are the pin control fixes I have gathered since the return from
my vacation. They boiled in -next a while so let's get them in.
Apart from the documentation build it is purely driver fixes. Which is
nice. The Intel fixes seem kind of important.
- Fix the documentation build as the docs were moved
- Correct the UART pin list on the Intel Merrifield
- Fix pin assignment and number of pins on the Marvell Armada 37xx
pin controller
- Cover the Setzer models in the Chromebook DMI quirk in the Intel

* tag 'pinctrl-v4.13-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl:
pinctrl: generic: update references to Documentation/pinctrl.txt
pinctrl: intel: merrifield: Correct UART pin lists
pinctrl: armada-37xx: Fix number of pin in south bridge
pinctrl: armada-37xx: Fix the pin 23 on south bridge
pinctrl: cherryview: Add Setzer models to the Chromebook DMI quirk
pinctrl: sunxi: add a missing function of A10/A20 pinctrl driver
pinctrl: uniphier: fix USB3 pin assignment for Pro4
pinctrl: zte: fix dereference of 'data' in zx_set_mux()
Pin 23 on South bridge does not belong to the rgmii group. It belongs to
a separate group which can have 3 functions.
Due to this the fix also have to update the way the functions are
managed. Until now each groups used NB_FUNCS(which was 2) functions. For
the mpp23, 3 functions are available but it is the only group which needs
it, so on the loop involving NB_FUNCS an extra test was added to handle
only the functions added.
The bug was visible with the merge of the commit 07d065abf9 "arm64:
dts: marvell: armada-3720-db: Add vqmmc regulator for SD slot", the gpio
regulator used the gpio 23, due to this the whole rgmii group was setup
to gpio which broke the Ethernet support on the Armada 3720 DB
board. Thanks to this patch, the UHS SD cards (which need the vqmmc)
_and_ the Ethernet work again.
