2008-03-04ACPI: thinkpad-acpi: fix hotkey_get_tablet_modeHenrique de Moraes Holschuh
I used the wrong return convention on hotkey_get_tablet_mode(), breaking a lot of stuff. Bad Henrique! Fix it to return the status in the parameter-by-reference, and IO status on the function return value. Duh.

2008-02-16acer-wmi: Add DMI match for mail LED on Acer TravelMate 4200 seriesCarlos Corbacho

2008-02-16ACPI: thinkpad-acpi: add tablet-mode reportingHenrique de Moraes Holschuh
A quick study of the 0x5009/0x500A HKEY event on the X61t DSDT revealed the existence of the EC HTAB register (EC 0x0f, bit 7), and a compare with the X41t DSDT shows that HKEY.MHKG can be used to verify if the ThinkPad is tablet-capable (MHKG present), and in tablet mode (bit 3 of MHKG return is set). Add an attribute to report this information, "hotkey_tablet_mode". This attribute has poll()/select() support, and can be used along with EV_SW SW_TABLET_MODE to hook userspace to tablet events.

Issue EV_SW SW_TABLET_MODE events for HKEY events 0x5009 and 0x500A on the X41t/X60t/X61t. As usual, we suppress the HKEY events on the netlink interface to avoid sending duplicate events to userspace.

2008-02-16ACPI: thinkpad-acpi: make the video output feature optionalHenrique de Moraes Holschuh
The video output port control feature is not very useful on many ThinkPads (especially when a X server is running), and lately userspace is getting better and better at it, so it makes sense to allow users to stripe out the thinkpad-acpi video feature from their kernels and save at least 2KB.

2008-02-08acer-wmi, tc1100-wmi: select ACPI_WMILen Brown
It is safe for these Kconfig entries to use select because they select ACPI_WMI, which already has its dependencies satisfied. This makes Kconfig more user friendly, since the user selects the driver they want and the dependency is met for them. Otherwise, the user would have to find and enable ACPI_WMI to make enabling these drivers possible. Signed-off-by: Len Brown <len.brown@intel.com>

2008-02-01ACPI: thinkpad-acpi: wakeup on hotunplug reportingHenrique de Moraes Holschuh
Handle some HKEY events that the firmware uses to report the reason for a wake up, and to also notify that the system could go back to sleep (if it woke up just to eject something from the bay, or to undock). The driver will report the reason of the last wake up in the sysfs attribute "wakeup_reason": 0 for "none, unknown, or standard ACPI wake up event", 1 for "bay ejection request" and 2 for "undock request". The firmware will also report if the operation that triggered the wake up has been completed, by issuing an HKEY 0x3003 or 0x4003 event. If the operation fails, no event is sent. When such a hotunplug sucessfull notification is issued, the driver sets the attribute "wakeup_hotunplug_complete" to 1. While the firmware does tell us whether we are waking from a suspend or hibernation scenario, the Linux way of hibernating makes this information not reliable, and therefore it is not reported. The idea is that if any of these attributes are non-zero, userspace might want to do something at the end of the "wake up from sleep" procedures, such as offering to send the machine back into sleep as soon as it is safe to do so.
