Keng-Yu Lin a3d77411e8 dell-laptop: Toggle the unsupported hardware killswitch
It is found on Dell Inspiron 1018 that the firmware reports that the hardware
killswitch is not supported. This makes the rfkill key not functional.

This patch forces the driver to toggle the firmware rfkill status in the case
that the hardware killswitch is indicated as unsupported by the firmware.

Seth Forshee 5ffba7e696 thinkpad_acpi: Always report scancodes for hotkeys
Some thinkpad hotkeys report key codes like KEY_FN_F8 when something
like KEY_VOLUMEDOWN is desired. Always provide the scan codes in
addition to the key codes to assist with debugging these issues. Also
send the scan code before the key code to match what other drivers do,
as some userspace utilities expect this ordering.

Randy Dunlap ad0f43063e platform/x86: ideapad-laptop depends on INPUT
Most platform/x86 drivers that use INPUT_SPARSEKMAP also depend on INPUT,
so do the same for ideapad-laptop.  This fixes a kconfig warning and
subsequent build errors when CONFIG_INPUT is disabled.

Thomas Gleixner 98401ae434 platform-drivers: x86: pmic: Use request_irq instead of chained handler
There is no need to install a chained handler for this hardware. This
is a plain x86 IOAPIC interrupt which is handled by the core code
perfectly fine. There is nothing special about demultiplexing these
gpio interrupts which justifies a custom hack. Replace it by a plain
old interrupt handler installed with request_irq. That makes the code
agnostic about the underlying primary interrupt hardware. The overhead
for this is minimal, but it gives us the advantage of accounting,
balancing and to detect interrupt storms. gpio interrupts are not
really that performance critical.

Thomas Gleixner d4b7de612d platform-drivers: x86: pmic: Use irq_chip buslock mechanism
The set_type function of the pmic irq chip is a horrible hack. It
schedules work because it cannot access the scu chip from the set_type
function. That breaks the assumption, that the type is set after
set_type has returned.

irq_chips provide buslock functions to avoid the above. Convert the
driver to use the proper model.

Thomas Gleixner 180e9d19ee platform-drivers: x86: pmic: Fix up bogus irq hackery
commit 456dc301([PATCH] intel_pmic_gpio: modify EOI handling following
change of kernel irq subsystem) changes

-	desc->chip->eoi(irq);
+
+	if (desc->chip->irq_eoi)
+		desc->chip->irq_eoi(irq_get_irq_data(irq));
+	else
+		dev_warn(pg->chip.dev, "missing EOI handler for irq %d\n", irq);

With the following explanation:

 "Latest kernel has many changes in IRQ subsystem and its interfaces,
  like adding irq_eoi" for struct irq_chip, this patch will make it
  support both the new and old interface."

This is completely bogus.

#1) The changelog does not match the patch at all

#2) This driver relies on the assumption that it sits behind an eoi
    capable interrupt line. If the implementation of the underlying
    chip changes from eoi to irq_eoi then this driver has to follow
    that change and not add a total bogosity.

Remove the sillyness and retrieve the interrupt data from irq_desc
directly. No need to got through circles to look it up.

Mark Brown 0c51a4d8ab platform/x86: Consistently select LEDS Kconfig options
Currently the x86 platform devices are not consistent about selecting
or depending on the LEDs Kconfig variables, and this inconsistency
leads to Kconfig getting upset and refusing to offer LEDs (even on
non-x86 platforms):

drivers/platform/x86/Kconfig:422:error: recursive dependency detected!
drivers/platform/x86/Kconfig:422:       symbol EEEPC_WMI depends on ACPI_WMI
drivers/platform/x86/Kconfig:438:       symbol ACPI_WMI is selected by ACER_WMI
drivers/platform/x86/Kconfig:18:        symbol ACER_WMI depends on LEDS_CLASS
drivers/leds/Kconfig:10:        symbol LEDS_CLASS is selected by EEEPC_WMI

Fix this by always selecting rather than depending on the symbols as
slightly more drivers use this approach already and it seems more
user friendly.

Corentin Chary d358cb55a4 eeepc-wmi: never load if legacy device is enabled
If legacy device (SB.ATKD - ASUS010) used by eeepc-laptop
is enabled, don't allow eeepc-wmi to load because:
- eeepc-laptop may be loaded, and can conflict with
  eeepc-wmi (they both try to register eeepc::touchpad
  led for example).
- the WMI interface is inteded to be used when the OS is
  not detected as Win 7. And when this is the case, the
  ASUS010 device is disabled.

Corentin Chary 4c4edfa3d3 eeepc-wmi: claim eeepc-wmi maintainership
Since eeepc-wmi has currently no official maintainer, I claim
maintainership of this driver, and add it to the acpi4asus project.

Corentin Chary 8c1b2d83e8 eeepc-wmi: add debugfs entries
eeepc-wmi/    - debugfs root directory
  dev_id      - current dev_id
  ctrl_param  - current ctrl_param
  devs        - call DEVS(dev_id, ctrl_param) and print result
  dsts        - call DSTS(dev_id)  and print result

DEVS and DSTS are the main functions used in eeepc-wmi, this
will allow to test new features without patching the drivers.

Corentin Chary 27c136c873 eeepc-wmi: rework eeepc_wmi_init and eeepc_wmi_exit
The old code was using platform_driver.probe to initialize
eeepc_wmi context. That's a mistake because if probe fail,
eeepc_platform_register() won't tell anyone, and chaos will happen.

Wrap add and remove code inside eeepc_wmi_add() / eeepc_wmi_remove(),
and try to use the static platform_device only in eeepc_wmi_init()
and eeepc_wmi_exit()

The code is now very similar to eeepc-laptop, except eeepc_laptop_add
and eeepc_laptop_remove are called from acpi_driver, not module
init/exit functions, but WMI doesn't provide such functionalities (yet ?).

Herton Ronaldo Krzesinski 698e1641a3 classmate-laptop: little optimization for cmpc_rfkill_block
We don't need to call bios/acpi (cmpc_set_rfkill_wlan) if the blocked
state is already set to the same value (little optimization). This can
happen for example if we initialize the module with same initial
hardware state (rfkill core always call cmpc_rfkill_block on
initialization here).

Also GWRI method only accepts 0 or 1 for setting rfkill block, as can be
seen on AML code from acpidump->DSDT from a classmate sample I have, so
should be fine setting state only to 0 or 1 directly.
