[PATCH 0/2] Asus Wireless Radio Control driver

[João Paulo Rechi Vita]

This series implements the driver for the "Asus Wireless Radio Control" device,
as named on the vendor website, which handles notifications from the airplane
mode hotkey and drives the airplane mode indicator LED. This device appears in
the DSDT as "ASHS".

I decided to split the series and move the commits that drive the LED to a
separate series, so this part can be merged without waiting for feedback on the
new airplane mode RFKill LED trigger.

Regards,

Joao Paulo

[PATCH 1/2] platform/x86: Add Asus Wireless Radio Control driver

[João Paulo Rechi Vita]

Some Asus notebooks like the Asus E202SA and the Asus X555UB have a
separate ACPI device for notifications from the airplane mode hotkey.
This device is called "Wireless Radio Control" in Asus websites and ASHS
in the DSDT, and its ACPI _HID is ATK4002 in the two models mentioned
above.

For these models, when the airplane mode hotkey (Fn+F2) is pressed, a
query 0x0B is started in the Embedded Controller, and all this query does
is a notify ASHS with the value 0x88 (for acpi_osi >= "Windows 2012"):

	Scope (_SB.PCI0.SBRG.EC0)
	{
		(...)
		Method (_Q0B, 0, NotSerialized)  // _Qxx: EC Query
		{
			If ((MSOS () >= OSW8))
			{
				Notify (ASHS, 0x88) // Device-Specific
			}
			Else
			{
				(...)
			}
		}
	}

Few nitpicks below. In any case looks fine to me.

Hmm… Usually we leave this for OSVs (OS Vendors) to decide. Or, like
you mentioned below, to the user.

I would suggest
*inputdev -> *idev

In ACPI code and drivers we usually use struct acpi_device *adev.

I believe %#X will work in both cases instead of 0x%X

[PATCH] platform/x86: Add Asus Wireless Radio Control driver

[João Paulo Rechi Vita]

Some Asus notebooks like the Asus E202SA and the Asus X555UB have a
separate ACPI device for notifications from the airplane mode hotkey.
This device is called "Wireless Radio Control" in Asus websites and ASHS
in the DSDT, and its ACPI _HID is ATK4002 in the two models mentioned
above.

For these models, when the airplane mode hotkey (Fn+F2) is pressed, a
query 0x0B is started in the Embedded Controller, and all this query does
is a notify ASHS with the value 0x88 (for acpi_osi >= "Windows 2012"):

	Scope (_SB.PCI0.SBRG.EC0)
	{
		(...)
		Method (_Q0B, 0, NotSerialized)  // _Qxx: EC Query
		{
			If ((MSOS () >= OSW8))
			{
				Notify (ASHS, 0x88) // Device-Specific
			}
			Else
			{
				(...)
			}
		}
	}
