As a preparatory patch switch the driver to distinguish IRQ resource type.
For now, only GpioInt() is supported.

count the real amount provided by firmware.

Now, when i2c_acpi_new_device() never returns NULL, there is no point to check
for it. Besides that, i2c_acpi_new_device() returns -EPROBE_DEFER directly and
caller doesn't need to guess is better.

The caller would like to know the reason why the i2c_acpi_new_device() fails.
For example, if adapter is not available, it might be in the future and we
would like to re-probe the clients again. But at the same time we would like to
bail out if the error seems unrecoverable, such as invalid argument supplied.
To achieve this, return error pointer in some cases.

According to Asus firmware engineers, the meaning of these codes is only
to notify the OS that the screen brightness has been turned on/off by
the EC. This does not match the meaning of KEY_DISPLAYTOGGLE /
KEY_DISPLAY_OFF, where userspace is expected to change the display
brightness.

When the OS registers to handle events from the display off hotkey the
EC will send a notification with 0x35 for every key press, independent
of the backlight state.
The behavior of this key on Windows, with the ATKACPI driver from Asus
installed, is turning off the backlight of all connected displays with a
fading effect, and any cursor input or key press turning the backlight
back on. The key press or cursor input that wakes up the display is also
passed through to the application under the cursor or under focus.
The key that matches this behavior the closest is KEY_SCREENLOCK.

In the past, Asus firmwares would change the panel backlight directly
through the EC when the display off hotkey (Fn+F7) was pressed, and
only notify the OS of such change, with 0x33 when the LCD was ON and
0x34 when the LCD was OFF. These are currently mapped to
KEY_DISPLAYTOGGLE and KEY_DISPLAY_OFF, respectively.
Most recently the EC on Asus most machines lost ability to toggle the
LCD backlight directly, but unless the OS informs the firmware it is
going to handle the display toggle hotkey events, the firmware still
tries change the brightness through the EC, to no effect. The end result
is a long list (at Endless we counted 11) of Asus laptop models where
the display toggle hotkey does not perform any action. Our firmware
engineers contacts at Asus were surprised that there were still machines
out there with the old behavior.
Calling WMNB(ASUS_WMI_DEVID_BACKLIGHT==0x00050011, 2) on the _WDG device
tells the firmware that it should let the OS handle the display toggle
event, in which case it will simply notify the OS of a key press with
0x35, as shown by the DSDT excerpts bellow.

keycodes/evdev:

symbols/inet:

IDT PCIe-switch temperature sensor interface is very broken. First
of all only a few combinations of TMPCTL threshold enable bits
really cause the interrupts unmasked. Even if an individual bit
indicates the event unmasked, corresponding IRQ just isn't generated.
Most of the threshold enable bits combinations are in fact useless and
non of them can help to create a fully functional alarm interface.
So to speak, we can't create a well defined hwmon alarms based on
the IDT PCI-switch threshold IRQs.
Secondly a single threshold IRQ (not a combination of thresholds) can
be successfully enabled without the issue described above. But in this
case we experienced an enormous number of interrupts generated by
the chip if the temperature got near the enabled threshold value. Filter
adjustment didn't help much. It also doesn't provide a hysteresis settings.
Due to the temperature sample fluctuations near the threshold the
interrupts spate makes the system nearly unusable until the temperature
value finally settled so being pushed either to be fully higher or lower
the threshold.
All of these issues makes the temperature sensor alarm interface useless
and even at some point dangerous to be used in the driver. In this case
it is safer to completely discard it and disable the temperature alarm
interrupts.

IDT PCIe switches provide an embedded temperature sensor working
within [0; 127.5]C with resolution of 0.5C. They also can generate
a PCIe upstream interrupt in case if the temperature passes through
specified thresholds. Since this thresholds interface is very broken
the created hwmon-sysfs interface exposes only the next set of hwmon
nodes: current input temperature, lowest and highest values measured,
history resetting, value offset. HWmon alarm interface isn't provided.
IDT PCIe switch also've got an ADC/filter settings of the sensor.
This driver doesn't expose them to the hwmon-sysfs interface at the
moment, except the offset node.

In order to create a hwmon interface for the IDT PCIe-switch temperature
sensor the already available reader method should be improved. Particularly
we need to redesign it so one would be able to read temperature/offset
values from registers of the passed types. Since IDT sensor interface
provides temperature in unsigned format 0:7:1 (7 bits for real value
and one for fraction) we also need to have helpers for the typical sysfs
temperature data type conversion to and from this format. Even though
the IDT PCIe-switch provided temperature offset got the same but signed
type it can be translated by these methods too.

IDT NTB driver sets the upper limit of actual translation address
being written to the corresponding memory window setup. It is achieved
by BARLIMITx register initialization. Needless to say, that the register
works within PCIe bus address space.
In general CPU and PCIe address spaces are different. It means,
that addresses used for Memory TLPs routine can be different from
CPU addresses. While in most of cases they are the same, there are
exceptions when the proper mapping must be performed to have the
portable driver code. There used to be a virt_to_bus()/bus_to_virt()
interface for this purpose. But it's deprecated now. It was also a
mistake to use pci_resource_start() since the return address of the
method is at the CPU address space. In order to achieve the desired
purpose we need to use pci_bus_address() helper. This method shall
return a PCIe bus base address of the corresponding BAR resource.

Both devm_kcalloc() and devm_kzalloc() return NULL on error. They
never return error pointers.
The use of IS_ERR_OR_NULL is currently applied to the wrong
context.
Fix this by replacing IS_ERR_OR_NULL with regular NULL checks.

Now that in_compat_syscall() is consistent on all architectures and does
not longer report true on native i686, the workarounds (ifdeffery and
helpers) can be removed.

The Keystone QMSS driver is pretty damaged, in the sense that it
does things like this:
irq_set_affinity_hint(irq, to_cpumask(&cpu_map));
where cpu_map is a local variable. As we leave the function, this
will point to nowhere-land, and things will end-up badly.
Instead, let's use a proper cpumask that gets allocated, giving
the driver a chance to actually work with things like irqbalance
as well as have a hypothetical 64bit future.
