e9945b2633 pinctrl: ocelot: Fix incorrect trigger of the interrupt.
The interrupt controller can detect only link changes. So in case an
external device generated a level based interrupt, then the interrupt
controller detected correctly the first edge. But the problem was that
the interrupt controller was detecting also the edge when the interrupt
was cleared. So it would generate another interrupt.
The fix for this is to clear the second interrupt but still check the
interrupt line status.

This reverts commit ad2bea79ef.

On systems with older PMUFW (Xilinx ZynqMP Platform Management Firmware)
using these pinctrl properties can cause system hang because there is
missing feature autodetection.
When this feature is implemented in the PMUFW, support for these two
properties should bring back.

d21f4b7ffc pinctrl: qcom: Avoid glitching lines when we first mux to output
Back in the description of commit e440e30e26 ("arm64: dts: qcom:
sc7180: Avoid glitching SPI CS at bootup on trogdor") we described a
problem that we were seeing on trogdor devices. I'll re-summarize here
but you can also re-read the original commit.

On trogdor devices, the BIOS is setting up the SPI chip select as:
- mux special function (SPI chip select)
- output enable
- output low (unused because we've muxed as special function)

In the kernel, however, we've moved away from using the chip select
line as special function. Since the kernel wants to fully control the
chip select it's far more efficient to treat the line as a GPIO rather
than sending packet-like commands to the GENI firmware every time we
want the line to toggle.

When we transition from how the BIOS had the pin configured to how the
kernel has the pin configured we end up glitching the line. That's
because we _first_ change the mux of the line and then later set its
output. This glitch is bad and can confuse the device on the other end
of the line.

The old commit e440e30e26 ("arm64: dts: qcom: sc7180: Avoid
glitching SPI CS at bootup on trogdor") fixed the glitch, though the
solution was far from elegant. It essentially did the thing that
everyone always hates: encoding a sequential program in device tree,
even if it's a simple one. It also, unfortunately, got broken by
commit b991f8c362 ("pinctrl: core: Handling pinmux and pinconf
separately"). After that commit we did all the muxing _first_ even
though the config (set the pin to output high) was listed first. :(

I looked at ideas for how to solve this more properly. My first
thought was to use the "init" pinctrl state. In theory the "init"
pinctrl state is supposed to be exactly for achieving glitch-free
transitions. My dream would have been for the "init" pinctrl to do
nothing at all. That would let us delay the automatic pin muxing until
the driver could set things up and call pinctrl_init_done(). In other
words, my dream was:

  /* Request the GPIO; init it 1 (because DT says GPIO_ACTIVE_LOW) */
  devm_gpiod_get_index(dev, "cs", GPIOD_OUT_LOW);
  /* Output should be right, so we can remux, yay! */
  pinctrl_init_done(dev);

Unfortunately, it didn't work out. The primary reason is that the MSM
GPIO driver implements gpio_request_enable(). As documented in
pinmux.h, that function automatically remuxes a line as a GPIO. ...and
it does this remuxing _before_ specifying the output of the pin. You
can see in gpiod_get_index() that we call gpiod_request() before
gpiod_configure_flags(). gpiod_request() isn't passed any flags so it
has no idea what the eventual output will be.

We could have debates about whether or not the automatic remuxing to
GPIO for the MSM pinctrl was a good idea or not, but at this point I
think there is a plethora of code that's relying on it and I certainly
wouldn't suggest changing it.

Alternatively, we could try to come up with a way to pass the initial
output state to gpio_request_enable() and plumb all that through. That
seems like it would be doable, but we'd have to plumb it through
several layers in the stack.

This patch implements yet another alternative. Here, we specifically
avoid glitching the first time a pin is muxed to GPIO function if the
direction of the pin is output. The idea is that we can read the state
of the pin before we set the mux and make sure that the re-mux won't
change the state.

NOTES:
- We only do this the first time since later swaps between mux states
  might want to preserve the old output value. In other words, I
  wouldn't want to break a driver that did:
     gpiod_set_value(g, 1);
     pinctrl_select_state(pinctrl, special_state);
     pinctrl_select_default_state();
     /* We should be driving 1 even if "special_state" made the pin 0 */
- It's safe to do this the first time since the driver _couldn't_ have
  explicitly set a state. In order to even be able to control the GPIO
  (at least using gpiod) we have to have requested it which would have
  counted as the first mux.
- In theory, instead of keeping track of the first time a pin was set
  as a GPIO we could enable the glitch-free behavior only when
  msm_pinmux_request_gpio() is in the callchain. That works an enables
  my "dream" implementation above where we use an "init" state to
  solve this. However, it's nice not to have to do this. By handling
  just the first transition to GPIO we can simply let the normal
  "default" remuxing happen and we can be assured that there won't be
  a glitch.

Before this change I could see the glitch reported on the EC console
when booting. It would say this when booting the kernel:
  Unexpected state 1 in CSNRE ISR

After this change there is no error reported.

Note that I haven't reproduced the original problem described in
e440e30e26 ("arm64: dts: qcom: sc7180: Avoid glitching SPI CS at
bootup on trogdor") but I could believe it might happen in certain
timing conditions.

[   29.211095] PM: resume from suspend-to-idle

* IRQ9 on this laptop is used for the ACPI SCI.
* IRQ7 on this laptop is used for the GPIO controller.

What has occurred is when the lid was closed the EC woke up the
SoC from it's deepest sleep state and the kernel's s2idle loop
processed all EC events.  When it was finished processing EC events,
it checked for any other reasons to wake (break the s2idle loop).

The IRQ for the GPIO controller was active so the loop broke, and
then this IRQ was processed.  This is not a kernel bug but it is
certainly a surprising behavior, and to better debug it we should
have a dynamic debugging message that we can enact to catch it.

Adding support for line bias flags that have been implented in gpio API.
There are functions in the gpiod library that can control line bias from
userspace this adds that functionality to this driver.

Adding .pin_config_set allows the driver's pin configuration to be
accessed from userspace. The general idea for this as been taken from
stm32, intel, and rockchip drivers that have userspace access for bias
flags.

e75729b2f6 pinctrl: st: stop abusing of_get_named_gpio()
Pin descriptions for this chip only look like standard GPIO device tree
descriptions, while in fact they contain additional data (in excess of
number of cells specified in description of gpio controllers). They also
refer to only pins/gpios belonging to the driver and not to arbitrary
gpio in the system.

Because we want to stop exporting OF-specific handlers from gpiolib-of,
let's parse the pin reference ourself instead of trying to call
of_get_named_gpio().

4635c0e2a7 pinctrl: rockchip: add pinmux_ops.gpio_set_direction callback
Before the split of gpio and pinctrl sections in their own driver,
rockchip_set_mux was called in pinmux_ops.gpio_set_direction for
configuring a pin in its GPIO function.

This is essential for cases where pinctrl is "bypassed" by gpio
consumers otherwise the GPIO function is not configured for the pin and
it does not work. Such was the case for the sysfs/libgpiod userspace
GPIO handling.

Let's re-implement the pinmux_ops.gpio_set_direction callback so that
the gpio subsystem can request from the pinctrl driver to put the pin in
its GPIO function.

c297561bc9 pinctrl: ocelot: Fix interrupt controller
When an external device generated a level based interrupt then the
interrupt controller could miss the interrupt. The reason is that the
interrupt controller can detect only link changes.

In the following example, if there is a PHY that generates an interrupt
then the following would happen. The GPIO detected that the interrupt
line changed, and then the 'ocelot_irq_handler' was called. Here it
detects which GPIO line saw the change and for that will call the
following:
1. irq_mask
2. phy interrupt routine
3. irq_eoi
4. irq_unmask

And this works fine for simple cases, but if the PHY generates many
interrupts, for example when doing PTP timestamping, then the following
could happen. Again the function 'ocelot_irq_handler' will be called
and then from here the following could happen:
1. irq_mask
2. phy interrupt routine
3. irq_eoi
4. irq_unmask

Right before step 3(irq_eoi), the PHY will generate another interrupt.
Now the interrupt controller will acknowledge the change in the
interrupt line. So we miss the interrupt.

A solution will be to use 'handle_level_irq' instead of
'handle_fasteoi_irq', because for this will change routine order of
handling the interrupt.
1. irq_mask
2. irq_ack
3. phy interrupt routine
4. irq_unmask

And now if the PHY will generate a new interrupt before irq_unmask, the
interrupt controller will detect this because it already acknowledge the
change in interrupt line at step 2(irq_ack).

But this is not the full solution because there is another issue. In
case there are 2 PHYs that share the interrupt line. For example phy1
generates an interrupt, then the following can happen:
1.irq_mask
2.irq_ack
3.phy0 interrupt routine
4.phy1 interrupt routine
5.irq_unmask

In case phy0 will generate an interrupt while clearing the interrupt
source in phy1, then the interrupt line will be kept down by phy0. So
the interrupt controller will not see any changes in the interrupt line.
The solution here is to update 'irq_unmask' such that it can detect if
the interrupt line is still active or not. And if it is active then call
again the procedure to clear the interrupts. But we don't want to do it
every time, only if we know that the interrupt controller has not seen
already that the interrupt line has changed.

While at this, add support also for IRQ_TYPE_LEVEL_LOW.

When the driver want to disable the signal of the function, it doesn't
need to query the state of the mux function's signal on a pin. The
condition below will miss the disable of the signal:
Ball | Default | P0 Signal | P0 Expression               | Other
-----+---------+-----------+-----------------------------+----------
 E21   GPIOG0    SD2CLK      SCU4B4[16]=1 & SCU450[1]=1    GPIOG0
-----+---------+-----------+-----------------------------+----------
 B22   GPIOG1    SD2CMD      SCU4B4[17]=1 & SCU450[1]=1    GPIOG1
-----+---------+-----------+-----------------------------+----------
Assume the register status like below:
SCU4B4[16] == 1 & SCU4B4[17] == 1 & SCU450[1]==1
After the driver set the Ball E21 to the GPIOG0:
SCU4B4[16] == 0 & SCU4B4[17] == 1 & SCU450[1]==0
When the driver want to set the Ball B22 to the GPIOG1, the condition of
the SD2CMD will be false causing SCU4B4[17] not to be cleared.

67f40373ee pinctrl: qcom: Add sc8280xp lpass lpi pinctrl driver
Add pinctrl driver to support pin configuration for LPASS
(Low Power Audio SubSystem) LPI (Low Power Island) pinctrl
on SC8280XP.

This IP is an additional pin control block for Audio Pins on top the
existing SoC Top level pin-controller.

Hardware setup looks like:

    TLMM GPIO[189 - 207] --> LPASS LPI GPIO [0 - 18]

This pin controller has some similarities compared to Top level
msm SoC Pin controller like 'each pin belongs to a single group'
and so on. However this one is intended to control only audio
pins in particular, which can not be configured/touched by the
Top level SoC pin controller except setting them as gpios.
Apart from this, slew rate is also available in this block for
certain pins which are connected to SLIMbus or SoundWire Bus.

Add support for cypress I2C GPIO expanders cy8c9520, cy8c9540 and
cy8c9560. The GPIO expanders feature a PWM mode, thus add it as
pinctrl driver.

The chip features multiple drive modes for each pin when configured
as output and multiple bias settings when configured as input.

Tested all three components and verified that all functionality
is fully working.

The output is currently split across two lines making it more
difficult to parse unless the newlines are removed between pins
or it's read in by a parser like Libreoffice Calc or Google docs.

To make it easier to follow to the naked eye in a terminal window:
* drop the newline in the middle of pin definitions
* shorten all output using unicode characters
* align all pipe delimitters
* output the same phrase even for disabled functions
  (but with a ∅ character)

4546760619 pinctrl: armada-37xx: use raw spinlocks for regmap to avoid invalid wait context
The irqchip->irq_set_type method is called by __irq_set_trigger() under
the desc->lock raw spinlock.

The armada-37xx implementation, armada_37xx_irq_set_type(), uses an MMIO
regmap created by of_syscon_register(), which uses plain spinlocks
(the kind that are sleepable on RT).

Therefore, this is an invalid locking scheme for which we get a kernel
splat stating just that ("[ BUG: Invalid wait context ]"), because the
context in which the plain spinlock may sleep is atomic due to the raw
spinlock. We need to go raw spinlocks all the way.

Make this driver create its own MMIO regmap, with use_raw_spinlock=true,
and stop relying on syscon to provide it.

This patch depends on commit 67021f25d9 ("regmap: teach regmap to use
raw spinlocks if requested in the config").

41ef3c1a6b pinctrl: Don't allow PINCTRL_AMD to be a module
It was observed that by allowing pinctrl_amd to be loaded
later in the boot process that interrupts sent to the GPIO
controller early in the boot are not serviced.  The kernel treats
these as a spurious IRQ and disables the IRQ.

This problem was exacerbated because it happened on a system with
an encrypted partition so the kernel object was not accesssible for
an extended period of time while waiting for a passphrase.

To avoid this situation from occurring, stop allowing pinctrl-amd
from being built as a module and instead require it to be built-in
or disabled.

0569af4811 pinctrl: sunxi: Add driver for Allwinner D1
This SoC contains a pinctrl with a new register layout. Use the variant
parameter to set the right register offsets. This pinctrl also increases
the number of functions per pin from 8 to 16, taking advantage of all 4
bits in the mux config field (so far, only functions 0-8 and 14-15 are
used). This increases the maximum possible number of functions.

622b681ef9 pinctrl: sunxi: Make some layout parameters dynamic
Starting with the D1/D1s/T113 SoC, Allwinner changed the layout of the
pinctrl registers. This new layout widens the drive level field, which
affects the pull register offset and the overall bank size.

In order to support multiple register layouts, some of the layout
parameters need to be set based on the pinctrl variant. This requires
passing the pinctrl struct pointer to the register/offset calculation
functions.

0bb95ae267 pinctrl: sunxi: Refactor register/offset calculation
Starting with the D1/D1s/T113 SoC, Allwinner changed the layout of the
pinctrl registers. This new layout widens the drive level field, which
affects the pull register offset and the overall bank size.

As a first step to support this, combine the register and offset
calculation functions, and refactor the math to depend on one constant
for field widths instead of three. This minimizes the code size impact
of making some of the factors dynamic.

While rewriting these functions, move them to the implementation file,
since that is the only file where they are used. And make the comment
more generic, without mentioning specific offsets/sizes.

The callers are updated to expect a shifted mask, and to use consistent
terminology (reg/shift/mask/val).

91a29af413 gpio: Remove dynamic allocation from populate_parent_alloc_arg()
The gpiolib is unique in the way it uses intermediate fwspecs
when feeding an interrupt specifier to the parent domain, as it
relies on the populate_parent_alloc_arg() callback to perform
a dynamic allocation.

This is pretty inefficient (we free the structure almost immediately),
and the only reason this isn't a stack allocation is that our
ThunderX friend uses MSIs rather than a FW-constructed structure.

Let's solve it by providing a new type composed of the union
of a struct irq_fwspec and a msi_info_t, which satisfies both
requirements. This allows us to use a stack allocation, and we
can move the handful of users to this new scheme.

Also perform some additional cleanup, such as getting rid of the
stub versions of the irq_domain_translate_*cell helpers, which
are never used when CONFIG_IRQ_DOMAIN_HIERARCHY isn't selected.

Tested on a Tegra186.

c606c2fde2 pinctrl: renesas: r8a779g0: Add missing PWM
R-Car V4H has PWM/PWM_A/PWM_B, but current PFC setting is mixed.
This patch adds missing PWM settings, and tidies these up.

According to Document, GP3_14 Function4 is PWM2_A,
but we can't select it at P1SR3[27:24].
This patch just ignore it for now.
