The Asus Zenbook Duo (UX8406MA) has a keyboard which can be
placed on the laptop to connect it via USB, or can be removed from the
laptop to reveal a hidden secondary display in which case the keyboard
operates via Bluetooth.
When it is placed on the secondary display to connect via USB, it emits
a keypress for a wireless disable. This causes the rfkill system to be
activated disconnecting the current wifi connection, which doesn't
reflect the user's true intention.
Detect this hardware and suppress any wireless switches from the
keyboard; this keyboard does not have a wireless toggle capability so
these presses are always spurious.

Change asus_q500a_i8042_filter() into a generic i8042-filter,
using a new filter_i8042_e1_extended_codes flag in the quirks struct
to decide if e1 extended codes should be filtered out or not.
This is a preparation patch for adding support for filtering volume key
events being reported twice through both the PS/2 keyboard and asus-wmi.
Note while modifying the code also drop the unnecessary unlikely()
annotations, this is not in a hot path so those are not necessary.

Older Asus laptops change the backlight level themselves and then send
WMI events with different codes for different backlight levels.
The asus-wmi.c code maps the entire range of codes reported on
brightness down keypresses to an internal ASUS_WMI_BRN_DOWN code:
define NOTIFY_BRNUP_MIN 0x11
define NOTIFY_BRNUP_MAX 0x1f
define NOTIFY_BRNDOWN_MIN 0x20
define NOTIFY_BRNDOWN_MAX 0x2e
if (code >= NOTIFY_BRNUP_MIN && code <= NOTIFY_BRNUP_MAX)
code = ASUS_WMI_BRN_UP;
else if (code >= NOTIFY_BRNDOWN_MIN && code <= NOTIFY_BRNDOWN_MAX)
code = ASUS_WMI_BRN_DOWN;
Before this commit all the NOTIFY_BRNDOWN_MIN - NOTIFY_BRNDOWN_MAX
aka 0x20 - 0x2e events were mapped to 0x20.
This mapping is causing issues on new laptop models which actually
send 0x2b events for printscreen presses and 0x2c events for
capslock presses, which get translated into spurious brightness-down
presses.
The plan is disable the 0x11-0x2e special mapping on laptops
where asus-wmi does not register a backlight-device to avoid
the spurious brightness-down keypresses. New laptops always send
0x2e for brightness-down presses, change the special internal
ASUS_WMI_BRN_DOWN value from 0x20 to 0x2e to match this in
preparation for fixing the spurious brightness-down presses.
This change does not have any functional impact since all
of 0x20 - 0x2e is mapped to ASUS_WMI_BRN_DOWN first and only
then checked against the keymap code and the new 0x2e
value is still in the 0x20 - 0x2e range.

Add support for the WMI methods used to turn off and adjust the
brightness of the secondary "screenpad" device found on some high-end
ASUS laptops like the GX650P series and others.
There are some small quirks with this device when considering only the
raw WMI methods:
1. The Off method can only switch the device off
2. Changing the brightness turns the device back on
3. To turn the device back on the brightness must be > 1
4. When the device is off the brightness can't be changed (so it is
stored by the driver if device is off).
5. Booting with a value of 0 brightness (retained by bios) means the bios
will set a value of >0 <15
6. When the device is off it is "unplugged"
asus_wmi sets the minimum brightness as 20 in general use, and 60 for
booting with values <= min.
The ACPI methods are used in a new backlight device named asus_screenpad.

The UX360CA has a WMI device id 0x00060062, which reports whether the
lid is flipped in tablet mode (1) or in normal laptop mode (0).
Add a quirk (quirk_asus_use_lid_flip_devid) for devices on which this
WMI device should be used to figure out the SW_TABLET_MODE state, as
opposed to the quirk_asus_use_kbd_dock_devid.
Additionally, the device needs to be queried on resume and restore
because the firmware does not generate an event if the laptop is put to
sleep while in tablet mode, flipped to normal mode, and later awoken.
It is assumed other UX360* models have the same WMI device. As such, the
quirk is applied to devices with DMI_MATCH(DMI_PRODUCT_NAME, "UX360").
More devices with this feature need to be tested and added accordingly.
The reason for using an allowlist via the quirk mechanism is that the new
WMI device (0x00060062) is also present on some models which do not have
a 360 degree hinge (at least FX503VD and GL503VD from Hans' DSTS
collection) and therefore its presence cannot be relied on.

Commit b0dbd97de1 ("platform/x86: asus-wmi: Add support for
SW_TABLET_MODE") added support for reporting SW_TABLET_MODE using the
Asus 0x00120063 WMI-device-id to see if various transformer models were
docked into their keyboard-dock (SW_TABLET_MODE=0) or if they were
being used as a tablet.
The new SW_TABLET_MODE support (naively?) assumed that non Transformer
devices would either not support the 0x00120063 WMI-device-id at all,
or would NOT set ASUS_WMI_DSTS_PRESENCE_BIT in their reply when querying
the device-id.
Unfortunately this is not true and we have received many bug reports about
this change causing the asus-wmi driver to always report SW_TABLET_MODE=1
on non Transformer devices. This causes libinput to think that these are
360 degree hinges style 2-in-1s folded into tablet-mode. Making libinput
suppress keyboard and touchpad events from the builtin keyboard and
touchpad. So effectively this causes the keyboard and touchpad to not work
on many non Transformer Asus models.
This commit fixes this by using the existing DMI based quirk mechanism in
asus-nb-wmi.c to allow using the 0x00120063 device-id for reporting
SW_TABLET_MODE on Transformer models and ignoring it on all other models.

Some revisions of the ASUS Q500A series have a keyboard related
issue which is reproducible only after Windows with installed ASUS
tools is started.
In this case the Linux side will have a blocked keyboard or
report incorrect or incomplete hotkey events.
To make Linux work properly again, a complete power down
(unplug power supply and remove battery) is needed.
Linux/atkbd after a clean start will get the following code on VOLUME_UP
key: {0xe0, 0x30, 0xe0, 0xb0}. After Windows, the same key will generate
this codes: {0xe1, 0x23, 0xe0, 0x30, 0xe0, 0xb0}. As result atkdb will
be confused by buggy codes.
This patch is filtering this buggy code out.

[dvhart: Add return after pr_warn to avoid false confirmation of filter]

acpi_video0 doesn't work, asus-wmi brightness interface doesn't work, too.
So, we use native brightness interface to handle the brightness adjustion,
and add quirk_asus_ux303ub.

Some Asus laptops that have an airplane-mode indicator LED, also have
the WMI WLAN user bit set, and the following bits in their DSDT:
Scope (_SB)
{
(...)
Device (ATKD)
{
(...)
Method (WMNB, 3, Serialized)
{
(...)
If (LEqual (IIA0, 0x00010002))
{
OWGD (IIA1)
Return (One)
}
}
}
}
So when asus-wmi uses ASUS_WMI_DEVID_WLAN_LED (0x00010002) to store the
wlan state, it drives the airplane-mode indicator LED (through the call
to OWGD) in an inverted fashion: the LED is ON when airplane mode is OFF
(since wlan is ON), and vice-versa.
This commit creates a quirk to not register a RFKill switch at all for
these laptops, to allow the asus-wireless driver to drive the airplane
mode LED correctly through the ASHS ACPI device. It also adds a match to
that quirk for the Asus X555UB, which is affected by this problem.

For machines with AMD graphic chips, it will send out WMI event and ACPI
interrupt at the same time while hitting the hotkey. BIOS will notify the
system the next display output mode throught WMI event code, so that
windows' application can show an OSD to tell the user which mode will be
taken effect. User can hit the display toggle key many times within 2
seconds to choose the mode they want. After 2 seconds, WMI dirver should
send a WMIMethod(SDSP) command to tell the BIOS which mode the user chose.
And then BIOS will raise another ACPI interrupt to tell the system to
really switch the display mode.
In Linux desktop, we don't have this kind of OSD to let users to choose
the mode they want, so we don't need to call WMIMethod(SDSP) to have
another ACPI interrupt. To simplify the problem, we just have to ignore
the WMI event, and let the first ACPI interrupt to send out the key event.
For the need, here comes another quirk to add machines with this kind of
behavior. When the WMI driver receives the display toggle WMI event, and
found the machin is in the list, it will do nothing and let ACPI video
driver to report the key event.

If the user bit is set, that mean BIOS can't set and record the wlan
status, it will report the value read from id ASUS_WMI_DEVID_WLAN_LED
(0x00010012) while we query the wlan status by id ASUS_WMI_DEVID_WLAN
(0x00010011) through WMI.
So, we have to record wlan status in id ASUS_WMI_DEVID_WLAN_LED
(0x00010012) while setting the wlan status through WMI.
This is also the behavior that windows app will do.

When you call WMIMethod(DSTS, 0x00010011) to get WLAN status, it may return
(1) 0x00050001 (On)
(2) 0x00050000 (Off)
(3) 0x00030001 (On)
(4) 0x00030000 (Off)
(5) 0x00000002 (Unknown)
(1), (2) means that the model has hardware GPIO for WLAN, you can call
WMIMethod(DEVS, 0x00010011, 1 or 0) to turn WLAN on/off.
(3), (4) means that the model doesn’t have hardware GPIO, you need to use
API or driver library to turn WLAN on/off, and call
WMIMethod(DEVS, 0x00010012, 1 or 0) to set WLAN LED status.
After you set WLAN LED status, you can see the WLAN status is changed with
WMIMethod(DSTS, 0x00010011). Because the status is recorded lastly
(ex: Windows), you can use it for synchronization.
(5) means that the model doesn’t have WLAN device.
WLAN is the ONLY special case with upper rule.
For other device, like Bluetooth, you just need use
WMIMethod(DSTS, 0x00010013) to get, and WMIMethod(DEVS, 0x00010013, 1 or 0)
to set.

Some h/w that can adjust screen brightness through ACPI functions, but
can't turn on/off the backlight power correctly. So, we list those h/w in
quirks and try to turn on/off the backlight power through WMI.

Some models work better with different values of wapf, so move the
variable into quriks_entry to make it more easy to give a specific
value to different models.

Due to some implementation reasons, ASUS ET2012 All-in-One machines
can't report the correct backlight power status, it will always return
1. To track the backlight power status correctly, we have to store the
status by ourselves.
BTW, by the BIOS design, the backlight power will be turn on/off
sequently, no matter what the value of the parameter will be.
More over, the brightness adjustment command will turn on the backlight
power. Those behaviors will make us fail to track the backlight power
status.
For example, While we are trying to turn on the backlight power,
we will send out the brightness adjustment command and then trying to
figure out if we have to turn on the backlight power, then send out
the command. But, the real case is that, the backlight power turns on
while sending the brightness adjustment command, and then we send out
the command to turn on the backlight power, it actually will turn off
the backlight power and the backlight power status we recorded becomes
wrong. So, we have to seperate these two commands by a if statement.

Some ASUS ET2012E/I All-in-One machines that use a scalar board
to control the brightness, and they only accept brightness up and down
command. So, I introduced a get_scalar_command() function to pass the
command to the scalar board through WMI.
Besides, we have to store the brightness value locally, for we need the
old value to know the brightness value is increasing or decreasing.
BTW, since there is no way to retrieve the actual brightness(it would be
a fixed value), and the max brightness value would be fixed to 1, so we
have to keep passing the brightness up/down command when we reached the
max brightness value or 0.

New Asus notebooks are using a WMI device similar to
the one used in Eee PCs. Since we don't want to load
eeepc-wmi module on Asus notebooks, and we want to
keep the eeepc-wmi module for backward compatibility,
this patch introduce a new module, named asus-wmi, that
will be used by eeepc-wmi and the new Asus Notebook WMI
Driver.
eeepc-wmi's input device strings (device name and phys)
are kept, but rfkill and led names are changed (s/eeepc/asus/).
This should not break anything since rfkill are used by type or
index, not by name, and the eeepc::touchpad led wasn't working
correctly before 2.6.39 anyway.
