* ideapad: add Lenovo IdeaPad Z570 support (part 3)Maxim Mikityanskiy2012-08-201-3/+40
| | | | | | | | | | | | | | | | 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()Carlos Alberto Lopez Perez2012-08-171-3/+9
| | | | | | | | | | | 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() Signed-off-by: Carlos Alberto Lopez Perez <clopez@igalia.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>
* thinkpad-acpi: recognize latest V-Series using DMI_BIOS_VENDORManoj Iyer2012-08-171-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* asus-wmi: record wlan status while controlled by userappAceLan Kao2012-08-172-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. === Signed-off-by: AceLan Kao <acelan.kao@canonical.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>

* x86: OLPC: switch over to using new EC driver on x86Andres Salomon2012-07-311-5/+0
| | | | | | | | | | | This uses the new EC driver framework in drivers/platform/olpc. The XO-1 and XO-1.5-specific code is still in arch/x86, but the generic stuff (including a new workqueue; no more running EC commands with IRQs disabled!) can be shared with other architectures.

* Platform: OLPC: add a suspended flag to the EC driverAndres Salomon2012-07-311-1/+45
| | | | | | | | | | | | | A problem we've noticed on XO-1.75 is when we suspend in the middle of an EC command. Don't allow that. In the process, create a private object for the generic EC driver to use; we have a framework for passing around a struct, use that rather than a proliferation of global variables.

* Platform: OLPC: turn EC driver into a platform_driverAndres Salomon2012-07-311-0/+48
| | | | | | | | | | | | | | The 1.75-based OLPC EC driver already does this; let's do it for all EC drivers. This gives us nice suspend/resume hooks, amongst other things. We want to run the EC's suspend hooks later than other drivers (which may be setting wakeup masks or be running EC commands). We also want to run the EC's resume hooks earlier than other drivers (which may want to run EC commands).

* Platform: OLPC: allow EC cmd to be overridden, and create a workqueue to call itAndres Salomon2012-07-311-2/+110
| | | | | | | | | | | | | | | | | This provides a new API allows different OLPC architectures to override the EC driver. x86 and ARM OLPC machines use completely different EC backends. The olpc_ec_cmd is synchronous, and waits for the workqueue to send the command to the EC. Multiple callers can run olpc_ec_cmd() at once, and they will by serialized and sleep while only one executes on the EC at a time. We don't provide an unregister function, as that doesn't make sense within the context of OLPC machines - there's only ever 1 EC, it's critical to functionality, and it certainly not hotpluggable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The BIOS of these machines will try to enable/disable wifi/bt in their own sqeuence. It won't read the enable/disable parameter in WMI command, but just iterates the wifi/bt's status described below 1st. enable wifi, enable bt 2nd. disable wifi, enable bt 3rd. enable wifi, disable bt 4th. disable wifi, disable bt That will totally mess up the rfkill status, since we will try to read wifi and bt's status and reset it again while booting up. To avoid this, these machines should set the wapf value to 4, that will let software totally control the wifi/bt's status and BIOS will do nothing instead of sending out the 0x88(KEY_RFKILL) event instead of 0x5e(wifi enable), 0x5f(wifi diable), 0x7d(bt enable), and 0x7e(bt disable) through WMI. With this patch[1], it will handle the KEY_RFKILL event correctly and will block/unblock wifi and bt together. 1. https://lkml.org/lkml/2012/5/21/75 Signed-off-by: AceLan Kao <acelan.kao@canonical.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the ASUS WMI spec., to enable resume on lid open should use the device ID(0x00120032), but it doesn't work indeed. After discussing with ASUS' BIOS engineer, they say wake on lid open doesn't have a uniq device ID(0x00120032) in the BIOS. It shares the same device ID with deep S3(0x00120031), and the deep S3(resume on lid open) is disable by default. Adding this option in asus wmi sysfs /sys/devices/platform/<platform>/lid_resume so that userspace apps can enable/disable this feature by themselves.
