ideapad: add Lenovo IdeaPad Z570 support (part 3)

2012-08-20T16:44:41+00:00

The patch adds support for Lenovo IdeaPad Z570 laptop. It makes all special
keys working, adds possibility to control fan like Windows does, controls
Touchpad Disabled LED, toggles touchpad state via keyboard controller and
corrects touchpad behavior on resume from suspend. It is new, modified
version of patch. Now it does not depend on psmouse and does not need patching
of input subsystem.

classmate-laptop: always call input_sync() after input_report_switch()

2012-08-17T21:34:42+00:00

Due to commit cdda911c34006f1089f3c87b1a1f31ab3a4722f2 evdev only
becomes readable when the buffer contains an EV_SYN/SYN_REPORT event.

So in order to read the tablet sensor data as it happens we need to
ensure that we always call input_sync() after input_report_switch()

thinkpad-acpi: recognize latest V-Series using DMI_BIOS_VENDOR

2012-08-17T21:34:42+00:00

In the latest V-series bios DMI_PRODUCT_VERSION does not contain
the string Lenovo or Thinkpad, but is set to the model number, this
causes the thinkpad_acpi module to fail to load. Recognize laptop
as Lenovo using DMI_BIOS_VENDOR instead, which is set to Lenovo.

Test on V490u

This patch was also test in a B485 where the thinkpad_acpi module does not
have any issues loading. But, I tested it to make sure this patch does not
break on already functioning models of Lenovo products.

asus-wmi: record wlan status while controlled by userapp

2012-08-17T21:34:39+00:00

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.

Quote from ASUS application engineer
===
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.
