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.

bias-high-impedance"
This reverts commit ad2bea79ef0144043721d4893eef719c907e2e63.
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.

Back in the description of commit e440e30e26dd ("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 e440e30e26dd ("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 b991f8c3622c ("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
e440e30e26dd ("arm64: dts: qcom: sc7180: Avoid glitching SPI CS at
bootup on trogdor") but I could believe it might happen in certain
timing conditions.

Some laptops have been reported to wake up from s2idle when plugging
in the AC adapter or by closing the lid. This is a surprising
behavior that is further clarified by commit cb3e7d624c3ff ("PM:
wakeup: Add extra debugging statement for multiple active IRQs").
With that commit in place the following interaction can be seen
when the lid is closed:
[ 28.946038] PM: suspend-to-idle
[ 28.946083] ACPI: EC: ACPI EC GPE status set
[ 28.946101] ACPI: PM: Rearming ACPI SCI for wakeup
[ 28.950152] Timekeeping suspended for 3.320 seconds
[ 28.950152] PM: Triggering wakeup from IRQ 9
[ 28.950152] ACPI: EC: ACPI EC GPE status set

[ 28.995075] ACPI: PM: Rearming ACPI SCI for wakeup
[ 28.995131] PM: Triggering wakeup from IRQ 9
[ 28.995271] ACPI: EC: ACPI EC GPE status set
[ 28.995291] ACPI: EC: ACPI EC GPE dispatched

[ 29.211095] Timekeeping suspended for 0.739 seconds
[ 29.211095] PM: Triggering wakeup from IRQ 9
[ 29.211079] PM: Triggering wakeup from IRQ 7
[ 29.211095] ACPI: PM: ACPI non-EC GPE wakeup
[ 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.

Pull ARM driver updates from Arnd Bergmann:
"The drivers branch for 6.1 is a bit larger than for most releases.
Most of the changes come from SoC maintainers for the drivers/soc
subsystem:
- A new driver for error handling on the NVIDIA Tegra 'control
backbone' bus.
- A new driver for Qualcomm LLCC/DDR bandwidth measurement
- New Rockchip rv1126 and rk3588 power domain drivers
- DT binding updates for memory controllers, older Rockchip SoCs,
various Mediatek devices, Qualcomm SCM firmware
- Minor updates to Hisilicon LPC bus, the Allwinner SRAM driver, the
Apple rtkit firmware driver, Tegra firmware
- Minor updates for SoC drivers (Samsung, Mediatek, Renesas, Tegra,
Qualcomm, Broadcom, NXP, ...)
There are also some separate subsystem with downstream maintainers
that merge updates this way:
- Various updates and new drivers in the memory controller subsystem
for Mediatek and Broadcom SoCs
- Small set of changes in preparation to add support for FF-A v1.1
specification later, in the Arm FF-A firmware subsystem
- debugfs support in the PSCI firmware subsystem"

Add the SoC name to make it more clear. Also the next generation StarFive
SoCs will use "pinctrl-starfive" as the core of StarFive pinctrl driver.
No functional change.

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().

fwnode_irq_get() can return zero to indicate IRQ mapping errors.
Handle this case by skipping the interrupt resource.
