2009-05-14eeepc-laptop: report brightness control events via the input layerDarren Salt
This maps the brightness control events to one of two keys, either KEY_BRIGHTNESSDOWN or KEY_BRIGHTNESSUP, as needed. Some mapping has to be done due to the fact that the BIOS reports them as <base value> + <current brightness index>; the selection is done according to the sign of the change in brightness (if this is 0, no keypress is reported).

2009-05-14eeepc-laptop: fix wlan rfkill state change during initAlan Jenkins
When an rfkill device is registered, the rfkill core will change its state to the system default. So we need to prepare for state changes *before* we register it. That means installing the eeepc-specific ACPI callback which handles the hotplug of the wireless network adaptor. This problem doesn't occur during normal operation. You have to 1) Boot with wireless enabled. eeepc-laptop should load automatically. 2) modprobe -r eeepc-laptop 3) modprobe eeepc-laptop On boot, the default rfkill state will be set to enabled. With the current core code, step 2) will disable the wireless. Therefore in step 3), the wireless will change state during registration, from disabled to enabled. But without this fix, the PCI device for the wireless adaptor will not appear.

2009-04-18thinkpad-acpi: fix LED blinking through timer triggerHenrique de Moraes Holschuh
The set_blink hook code in the LED subdriver would never manage to get a LED to blink, and instead it would just turn it on. The consequence of this is that the "timer" trigger would not cause the LED to blink if given default parameters. This problem exists since 2.6.26-rc1. To fix it, switch the deferred LED work handling to use the thinkpad-acpi-specific LED status (off/on/blink) directly. This also makes the code easier to read, and to extend later.

2009-04-04thinkpad-acpi: rework brightness supportHenrique de Moraes Holschuh
Refactor and redesign the brightness control backend... In order to fix bugzilla #11750... Add a new brightness control mode: support direct NVRAM checkpointing of the backlight level (i.e. store directly to NVRAM without the need for UCMS calls), and use that together with the EC-based control. Disallow UCMS+EC, thus avoiding races with the SMM firmware. Switch the models that define HBRV (EC Brightness Value) in the DSDT to the new mode. These are: T40-T43, R50-R52, R50e, R51e, X31-X41. Change the default for all other IBM ThinkPads to UCMS-only. The Lenovo models already default to UCMS-only.

2009-04-04thinkpad-acpi: restrict access to some firmware LEDsHenrique de Moraes Holschuh
Some of the ThinkPad LEDs indicate critical conditions that can cause data loss or cause hardware damage when ignored (e.g. force-ejecting a powered up bay; ignoring a failing battery, or empty battery; force- undocking with the dock buses still active, etc). On almost all ThinkPads, LED access is write-only, and the firmware usually does fire-and-forget signaling on them, so you effectively lose whatever message the firmware was trying to convey to the user when you override the LED state, without any chance to restore it. Restrict access to all LEDs that can convey important alarms, or that could mislead the user into incorrectly operating the hardware. This will make the Lenovo engineers less unhappy about the whole issue. Allow users that really want it to still control all LEDs, it is the unaware user that we have to worry about.

2009-04-04thinkpad-acpi: remove HKEY disable functionalityHenrique de Moraes Holschuh
The HKEY disable functionality basically cripples the entire event model of the ThinkPad firmware and of the thinkpad-acpi driver. Remove this functionality from the driver. HKEY must be enabled at all times while thinkpad-acpi is loaded, and disabled otherwise. For sysfs, according to the sysfs ABI and the thinkpad-acpi sysfs rules of engagement, we will just remove the attributes. This will be done in two stages: disable their function now, after two kernel releases, remove the attributes. For procfs, we call WARN(). If nothing triggers it, I will simply remove the enable/disable commands entirely in the future along with the sysfs attributes. I don't expect much, if any fallout from this. There really isn't any reason to mess with hotkey_enable or with the enable/disable commands to /proc/acpi/ibm/hotkey, and this has been true for years...
