| * backlight: Add WM831x backlight driverMark Brown2009-09-073-0/+258
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The WM831x series of PMICs provide DC-DC boost convertors and current sinks which can be used together to drive LEDs for use as backlights. Expose this functionality via the backlight API. Since when used in this configuration the current sink and boost convertor are very tightly coupled with a multi-stage startup for the current sink which overlaps with the boost convertor startup this driver bypasses the regulator API. Machine inititialisation is responsible for ensuring that the regulators are not accessed via both APIs.

* backlight: Add support for MacBook 5, MacBook Air 2, and MacBook Pro 5Mario Schwalbe2009-04-061-36/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the new Apple models incorporating an Nvidia chipset. Apple still uses the same protocol as on older models, but the registers moved to a different address. To do this, two sets of functions are added for the Intel/Nvidia chipset models and passed by the DMI_MATCH function. The initial code has been contributed by Hu Gang <hugang@soulinfo.com>. The driver is known to work on MacBook Pro 3, MacBook Pro 4 and MacBook Pro 5. Its known to work with limitations on MacBook 5 / MacBook Air 2. Changing brightness within X doesn't work, if using Nvidia's proprietary graphics driver with no known fix at present. Changing brightness on a text console or using the open-source driver does work. MacBook Pro 5 has a known bug where the initial brightness after bootup is the last recently used brightness (in Mac OSX), while the firmware reports maximum. Impossible to fix.

| | | | | | | | | | | | | | | | | | Fix a circular locking dependency in the frame buffer console driver pushing down the mutex fb_info->lock. Circular locking dependecies occur calling the blocking fb_notifier_call_chain() with fb_info->lock held. Notifier callbacks can try to acquire mm->mmap_sem, while fb_mmap() acquires the locks in the reverse order mm->mmap_sem => fb_info->lock.

| | | | | | | | | | | | | | | | The LCD driver core calls LCD drivers when either the blanking state or the display mode has changed, but does not make any check to see if the called driver has a .set_mode method.
