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.

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
dynamically"), the irqs for gpio are not statically allocated during in
gpiochip_irqchip_add.
This driver was based on this assumption for initializing the mask
associated to each interrupt this led to a NULL pointer crash in the

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

Intel Lewisburg has the same GPIO hardware than Intel Sunrisepoint-H
except few differences in register offsets and pin lists. Because of
this we add a separate pinctrl driver for Lewisburg.

This is desktop version Intel Cannon Lake PCH. The GPIO hardware is the
same but pin list differs a bit. Add support for this to the existing
Cannon Lake pin controller driver.

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.
