2007-02-20backlight: Separate backlight properties from backlight ops pointersRichard Purdie2-12/+13
Per device data such as brightness belongs to the indivdual device and should therefore be separate from the the backlight operation function pointers. This patch splits the two types of data and allows simplifcation of some code. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
2007-02-20backlight: Clean up pmac_backlight handlingRichard Purdie1-6/+9
Move the setting/unsetting of pmac_backlight into the backlight core instead of doing it in each driver. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
2007-02-20backlight: Fix external uses of backlight internal semaphoreRichard Purdie1-15/+5
backlight_device->sem has a very specific use as documented in the header file. The external users of this are using it for a different reason, to serialise access to the update_status() method. backlight users were supposed to implement their own internal serialisation of update_status() if needed but everyone is doing things differently and incorrectly. Therefore add a global mutex to take care of serialisation for everyone, once and for all. Locking for get_brightness remains optional since most users don't need it. Also update the lcd class in a similar way. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
2007-02-20backlight: Remove unneeded owner fieldRichard Purdie3-3/+0
Remove uneeded owner field from backlight_properties structure. Nothing uses it and it is unlikely that it will ever be used. The backlight class uses other means to ensure that nothing references unloaded code. Based on a patch from Dmitry Torokhov <dtor@insightbb.com> Signed-off-by: Richard Purdie <rpurdie@rpsys.net>

2007-02-04tifm_7xx1: switch from workqueue to kthreadAlex Dubov2-68/+94
As there's only one work item (media_switcher) to handle and it's effectively serialized with itself, I found it more convenient to use kthread instead of workqueue. This also allows for a working implementation of suspend/resume, which were totally broken in the past version.

2007-02-04tifm_7xx1: Merge media insert and media remove functionsAlex Dubov1-128/+126
Hardware does not say whether card was inserted or removed when reporting socket events. Moreover, during suspend, media can be removed or switched to some other card type without notification. Therefore, for each socket in the change set the following is performed: 1. If there's active device in the socket it's unregistered 2. Media detection is performed 3. If detection recognizes supportable media, new device is registered This patch also alters some macros and variable names to enhance clarity.

2007-02-04tifm_sd: restructure initialization, removal and command handlingAlex Dubov2-10/+4
In order to support correct suspend and resume several changes were needed: 1. Switch from work_struct to tasklet for command handling. When device suspend is called workqueues are already frozen and can not be used. 2. Separate host initialization code from driver's probe and don't rely on interrupts for host initialization. This, in turn, addresses two problems: a) Resume needs to re-initialize the host, but can not assume that device interrupts were already re-armed. b) Previously, probe will return successfully before really knowing the state of the host, as host interrupts were not armed in time. Now it uses polling to determine the real host state before returning. 3. Separate termination code from driver's remove. Termination may be caused by resume, if media changed type or became unavailable during suspend. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

2007-01-30asus-laptop: add backlight supportCorentin Chary2-1/+183
Adds backlight support using backlight class. We now change the brightness *and toggle the backlight !* via /sys/class/backlight/asus-laptop/. If the user switchs the backlight using the keyboard, asus_hotk_notify looks for ATKD_LCD_OFF and ATKD_LCD_ON events, and stores the right state into hotk->status and bd->props->power .

2007-01-30asus-laptop: add bluetooth and wlan supportCorentin Chary1-2/+113
WLED and BLED are not handled like other leds (MLED, etc ..), because sometime they also control the wlan/bluetooth device. If the method for wireless_status is found, it's used to get the status, otherwise hotk->status is used. We also use the HWRS method, which tell if the bluetooth/wlan device is present or not. This patch show why we need a ASUS_SET_DEVICE_ATTR macro : if there is a bluetooth device, /sys/dev.../asus-laptop/bluetooth is usable, else it's not but it's clean.

Add led support, using generic led class. Thomas Tuttle's patch <http://lkml.org/lkml/2006/7/6/247> was very usefull. We use hotk->status to store led status because it's very hard to find acpi method to get the right status... To reduce the code, I use a lot of macro (ASUS_LED, ASUS_LED_REGISTER, etc ...), because the code is the same for all leds ...

This patch set adds generic abstract layer support for acpi video driver to have generic user interface to control backlight and output switch control by leveraging the existing backlight sysfs class driver, and by adding a new video output sysfs class driver. This patch: Add dev argument for backlight_device_register to link the class device to real device object.
