This is based on the 2004 out-of-tree work of Jamey Hicks, to add support via WMI for controlling the jog dial and wireless on these tablets. v1: Original release v2: As per Joshua Wise's comments, change bluetooth to jogdial (an error from the original driver).

This is a driver for newer Acer (and Wistron) laptops. It adds wireless radio and bluetooth control, and on some laptops, exposes the mail LED and LCD backlight. v1: * Initial release v2: * Replace left over ACPI references with WMI * Add GUID based autoloading (depends on future work to WMI) * Add DMI based autoloading (backup solution until WMI sysfs/ class work is available) * Checkpatch fixes v3: * Add new EC quirks for Aspire 3100 & 5100, and Extensa 5220 v4: * Simplified internal handling of WMID and AMW0 devices * Add autodetection for bluetooth and maximum brightness on AMW0 V2 and WMID laptops. v5: * Add EC quirk for Medion MD 98000 * Add autodetection for AMW0, and mail LED on AMW0 and AMW0 V2. * Improve error handling * Fix AMW0 V2 bluetooth and wireless, by using both WMID and AMW0 methods to ensure that the correct value is always set. v6: * Fix 'use before initialisation' bug with quirks. v7 * Fix bug on AMW0 where acer-wmi would exit if a mail LED was not detected. * Add Acer Aspire 9110 mail LED support * Fix section mismatch warnings Signed-off-by: NCarlos Corbacho <carlos@strangeworlds.co.uk> CC: Matthew Garrett <mjg59@srcf.ucam.org> Signed-off-by: NLen Brown <len.brown@intel.com>

Starting in 2.6.23... Several reports from X60 users complained that the default Lenovo keymap issuing EV_KEY KEY_BRIGHTNESS_UP/DOWN input events caused major issues when the proper brightness support through ACPI video.c was loaded. Therefore, remove the generation of these events by default, which is the right thing for T60, X60, R60, T61, X61 and R61 with their latest BIOSes. Distros that want to misuse these events into OSD reporting (which requires an ugly hack from hell in HAL) are welcome to set up the key map they need through HAL. That way, we don't break everyone else's systems. Signed-off-by: NHenrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: NLen Brown <len.brown@intel.com>

set_ibm_param() could OOPS with a NULL pointer derreference if one did not give any values for a module parameter it handles. This would, of course, cause all sort of trouble for future modprobing and require a reboot to clean up properly. Fix it by returning -EINVAL if no values are given for the parameter, and also avoid any nastyness from BUG_ON while at it.

Map an mutex_lock_interruptible() error return into ERESTARTSYS, as the only possible error from mutex_lock_interruptible is EINTR, and that will only happen if signal_pending() causes the mutex lock attempt to abort. This still allows signals to be delivered ASAP, which is much nicer than just doing mutex_lock, and still shadows userspace from EINTR when SA_RESTART is active. Problem reported by Peter Jordan.

Newer Lenovo BIOSes support the standard ACPI backlight brightness interface (_BCM, _BQC, _BCL). It should be used instead of the native thinkpad backlight brightness control interface when possible. This patch disables the native brightness support in the driver by default when we detect that the standard ACPI interface is available. The local admin can still enable it using the module parameter "brightness_enable". Note that we need to detect the standard ACPI backlight interface only in boxes for which we would load the native backlight interface in the first place, and that no ThinkPad BIOS has _BCL but misses the other methods, so the detection routines can be really simple.

Add a "brightness_enable" module parameter that allows the local admin to force the backlight support to not be enabled. It can also be used to force the backlight support to be enabled, but that is currently a no-op as the backlight support is enabled by default when available. This will be changed by a different patch. Signed-off-by: NHenrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: NLen Brown <len.brown@intel.com>

Lenovo ThinkPads often have 16 brightness levels in EC, and not just eight levels like older ThinkPads. They also have standard ACPI backlight brightness control. We detect the number of brightness levels by the presence of a BCLL package with 16 entries. If BCLL is not there, we assume eight levels (Z6*). If it is there, but it doesn't have 16 entries, we assume eight levels (T60). Otherwise we assume sixteen levels (T61, X61, etc). We don't use _BCL because it can have side-effects in thinkpads. Thanks to Thomas Renninger <trenn@suse.de> for notifying me of this potential problem. Using the standard ACPI backlight brightness control *instead* of the native thinkpad backlight control is a better idea, though. A different patch will take care of this.

Revert commit fba956c4, "Map volume and brightness events on thinkpads". That commit made some modifications to the default keymaps that cause bad behaviour on all IBM ThinkPads if HAL doesn't know to change them into passive (on-screen-display only) events. The proper solution for IBM ThinkPads is to use the _NOTIFY version of the key codes for the IBM default map (which are not available in mainline yet), and for the Lenovo keymap, it will take some studying of the various DSDTs and testing to know the best path (which I will do shortly).

It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places.

Three main sets of changes: 1) dmi_get_system_info() return value should have been marked const, since callers should not be changing that data. 2) const-ify DMI internals, since DMI firmware tables should, whenever possible, be marked const to ensure we never ever write to that data area. 3) const-ify DMI API, to enable marking tables const where possible in low-level drivers. And if we're really lucky, this might enable some additional optimizations on the part of the compiler. The bulk of the changes are #2 and #3, which are interrelated. #1 could have been a separate patch, but it was so small compared to the others, it was easier to roll it into this changeset.
