asus-nb-wmi: add some video toggle keys

2012-09-12T02:37:36+00:00

commit 3766054fff4af1b58a1440a284907887f4d2e8be upstream.

There are some new video switch keys that used by newer machines.
0xA0 - SDSP HDMI only
0xA1 - SDSP LCD + HDMI
0xA2 - SDSP CRT + HDMI
0xA3 - SDSP TV + HDMI
But in Linux, there is no suitable userspace application to handle this,
so, mapping them all to KEY_SWITCHVIDEOMODE.

asus-wmi: use ASUS_WMI_METHODID_DSTS2 as default DSTS ID.

2012-08-09T23:24:57+00:00

commit 63a78bb1051b240417daad3a3fa9c1bb10646dca upstream.

According to responses from the BIOS team, ASUS_WMI_METHODID_DSTS2
(0x53545344) will be used as future DSTS ID. In addition, calling
asus_wmi_evaluate_method(ASUS_WMI_METHODID_DSTS2, 0, 0, NULL) returns
ASUS_WMI_UNSUPPORTED_METHOD in new ASUS laptop PCs. This patch fixes
no DSTS ID will be assigned in this case.

intel_ips: blacklist HP ProBook laptops

2012-07-25T03:11:21+00:00

commit 88ca518b0bb4161e5f20f8a1d9cc477cae294e54 upstream.

intel_ips driver spews the warning message
  "ME failed to update for more than 1s, likely hung"
at each second endlessly on HP ProBook laptops with IronLake.

As this has never worked, better to blacklist the driver for now.

samsung-laptop: make the dmi check less strict

2012-07-25T03:10:54+00:00

commit 3be324a94df0c3f032178d04549dbfbf6cccb09a upstream.

This enable the driver for everything that look like
a laptop and is from vendor "SAMSUNG ELECTRONICS CO., LTD.".
Note that laptop supported by samsung-q10 seem to have a different
vendor strict.

Also remove every log output until we know that we have a SABI interface
(except if the driver is forced to load, or debug is enabled).

Keeping a whitelist of laptop with a model granularity is something that can't
work without close vendor cooperation (and we don't have that).

sony-laptop: Enable keyboard backlight by default

2012-05-30T23:43:50+00:00

commit 6fe6ae56a7cebaebc2e6daa11c423e4692f9b592 upstream.

When the keyboard backlight support was originally added, the commit said
to default it to on with a 10 second timeout.  That actually wasn't the
case, as the default value is commented out for the kbd_backlight parameter.
Because it is a static variable, it gets set to 0 by default without some
other form of initialization.

However, it seems the function to set the value wasn't actually called
immediately, so whatever state the keyboard was in initially would remain.
Then commit df410d522410e67660 was introduced during the 2.6.39 timeframe to
immediately set whatever value was present (as well as attempt to
restore/reset the state on module removal or resume).  That seems to have
now forced the light off immediately when the module is loaded unless
the option kbd_backlight=1 is specified.

Let's enable it by default again (for the first time).  This should solve

acer-wmi: No wifi rfkill on Lenovo machines

2012-03-19T16:02:21+00:00

commit 461e74377cfcfc2c0d6bbdfa8fc5fbc21b052c2a upstream.

We have several reports which says acer-wmi is loaded on ideapads
and register rfkill for wifi which can not be unblocked.

Since ideapad-laptop also register rfkill for wifi and it works
reliably, it will be fine acer-wmi is not going to register rfkill
for wifi once VPC2004 is found.

Also put IBM0068/LEN0068 in the list. Though thinkpad_acpi has no
wifi rfkill capability, there are reports which says acer-wmi also
block wireless on Thinkpad E520/E420.
