When GPIOs that are routed to PDC are used as output they can still latch
the IRQ pending at GIC. As a result the spurious IRQ was handled when the
client driver change the direction to input to starts using it as IRQ.
Currently such erroneous latched IRQ are cleared with .irq_enable callback
however if the driver continue to use GPIO as interrupt and invokes
disable_irq() followed by enable_irq() then everytime during enable_irq()
previously latched interrupt gets cleared.
This can make edge IRQs not seen after enable_irq() if they had arrived
after the driver has invoked disable_irq() and were pending at GIC.
Move clearing erroneous IRQ to .irq_request_resources callback as this is
the place where GPIO direction is changed as input and its locked as IRQ.
While at this add a missing check to invoke msm_gpio_irq_clear_unmask()
from .irq_enable callback only when GPIO is not routed to PDC.

RTC is 32.768kHz thus 512 RtcClk equals 15625 usec. The documentation
likely has dropped precision and that's why the driver mistakenly took
the slightly deviated value.

It appears that simplification of mcp23s08_spi_regmap_init() made
a regression due to wrong size calculation for dev_kmemdup() call.
It misses the fact that config variable is already a pointer, thus
the sizeof() calculation is wrong and only 4 or 8 bytes were copied.
Fix the parameters to devm_kmemdup() to copy a full chunk of memory.

When GPIO library asks pin control to set the bias, it doesn't pass
any value of it and argument is considered boolean (and this is true
for ACPI GpioIo() / GpioInt() resources, by the way). Thus, individual
drivers must behave well, when they got the resistance value of 1 Ohm,
i.e. transforming it to sane default.
In case of Intel pin control hardware the 5 kOhm sounds plausible
because on one hand it's a minimum of resistors present in all
hardware generations and at the same time it's high enough to minimize
leakage current (will be only 200 uA with the above choice).

2 kOhm bias was never an option in Intel GPIO hardware, the available
matrix is:
000 none
001 1 kOhm (if available)
010 5 kOhm
100 20 kOhm
As easy to get the 3 resistors are gated separately and according to
parallel circuits calculations we may get combinations of the above where
the result is always strictly less than minimal resistance. Hence,
additional values can be:
011 ~833.3 Ohm
101 ~952.4 Ohm
110 ~4 kOhm
111 ~800 Ohm
That said, convert TERM definitions to be the bit masks to reflect the above.
While at it, enable the same setting for pull down case.

Core changes:
- The big core change is the updated (v2) userspace character
device API. This corrects badly designed 64-bit alignment around
the line events. We also add the debounce request feature.
This echoes the often quotes passage from Frederick Brooks
"The mythical man-month" to always throw one away, which we
have seen before in things such as V4L2. So we put in a new
one and deprecate and obsolete the old one.
- All example tools in tools/gpio/* are migrated to the new API
to set a good example. The libgpiod userspace library has been
augmented to use this new API pretty much from day 1.
- Some misc API hardening by using strn* function calls has been
added as well.
- Use the simpler IDA interface for GPIO chip instance enumeration.
- Add device core function for counting string arrays in
device properties.
- Provide a generic library function kfree_strarray() that can
be used throughout the kernel.
Driver enhancements:
- The DesignWare dwapb-gpio driver has been enhanced and now
uses the IRQ handling in the gpiolib core.
- The mockup and aggregator drivers have seen some substantial
code clean-up and now use more of the core kernel
inftrastructure.
- Misc cleanups using dev_err_probe().
- The MXC drivers (Freescale/NXP) can now be built modularized,
which makes modularized GKI Android kernels happy.

The Toshiba Visconti TMPV7700 series pin controller is only present on
Visconti SoCs. Hence add a dependency on ARCH_VISCONTI, to prevent
asking the user about this driver when configuring a kernel without
Visconti platform support.

msmgpio irqchip was not using return value of irq_set_irq_wake() callback
since previously GIC-v3 irqchip neither had IRQCHIP_SKIP_SET_WAKE flag nor
it implemented .irq_set_wake callback. This lead to irq_set_irq_wake()
return error -ENXIO.
However from 'commit 4110b5cbb0 ("irqchip/gic-v3: Allow interrupt to be
configured as wake-up sources")' GIC irqchip has IRQCHIP_SKIP_SET_WAKE
flag.
Use return value from irq_set_irq_wake() and irq_chip_set_wake_parent()
instead of always returning success.

Both IRQCHIP_SET_TYPE_MASKED and IRQCHIP_MASK_ON_SUSPEND flags are already
set for msmgpio's parent PDC irqchip but GPIO interrupts do not get masked
during suspend or during setting irq type since genirq checks irqchip flag
of msmgpio irqchip which forwards these calls to its parent PDC irqchip.
Add irqchip specific flags for msmgpio irqchip to mask non wakeirqs during
suspend and mask before setting irq type. Masking before changing type make
sures any spurious interrupt is not detected during this operation.

The Aspeed pinconf data structures are split into 'conf' and 'map'
types, where the 'conf' struct defines which register and bitfield to
manipulate, while the 'map' struct defines what value to write to
the register and bitfield.
Both structs have a mask member, and the wrong mask was being used to
tell the regmap which bits to update.
A todo is to look at whether we can remove the mask from the 'map'
struct.
