Novo key is the Lenovo define key on every ideapads, which has two definition. Long press and short click. Driver will report KEY_PROG1 on short click and KEY_PROG2 when long press. On pre-install OS for ideapads there are application waiting for the event and there is no such application for Linux yet, so I think to report KEY_PROG is fine in anyway. Also change the scancode from hex to decimal because they are related to vpc bit in notify function which is in decimal.

2011-10-24Platform: Detect samsung laptop quirk when initial level is zeroJohn Serock1-2/+8
This patch depends on the "Platform: Brightness quirk for samsung laptop driver" patch from Jason Stubbs. This patch adds a check for an initial brightness level of 0; if the level is 0, this patch changes the brightness level to 1 before the driver attempts to detect the brightness quirk. The Samsung N150 netbook experiences the brightness quirk. Without Jason's patch, the only brightness levels available on the N150 are 0, 1, and 8. This patch ensures that, when the initial brightness level is 0, the samsang-laptop driver detects the brightness quirk on the N150, thereby making brightness levels 0 through 8 available.

2011-10-24topstar-latop: ignore 0x82 eventManuel Lauss1-0/+1
Event 0x82 is emitted whenever a backlight event happens (brightness change, backlight on/off). For instance, when display is switched off after a timeout, event 0x82 is emitted, and along with it a keypress which switches the display back on again. This patch adds 0x82 to the event ignore list so that the display stays off when it is automatically switched off.

2011-10-24Platform: Brightness quirk for samsung laptop driverJason Stubbs1-0/+43
On some Samsung laptops the brightness regulation works slightly different. All SABI commands except for set_brightness work as expected. The behaviour of set_brightness is as follows: - Setting a new brightness will only step one level toward the new brightness level. For example, setting a level of 5 when the current level is 2 will result in a brightness level of 3. - A spurious KEY_BRIGHTNESS_UP or KEY_BRIGHTNESS_DOWN event is also generated along with the change in brightness. - Neither of the above two issues occur when changing from/to brightness level 0. This patch adds detection and a non-intrusive workaround for the above issues.

2011-10-24platform: samsung_laptop: fix samsung brightness min/max calculationsJason Stubbs1-3/+6
The min_brightness value of the sabi_config is incorrectly used in brightness calculations. For the config where min_brightness = 1 and max_brightness = 8, the user visible range should be 0 to 7 with hardware being set in the range of 1 to 8. What is actually happening is that the user visible range is 0 to 8 with hardware being set in the range of -1 to 7. This patch fixes the above issue as well as a miscalculation that would occur in the case of min_brightness > 1.
