Henrique de Moraes Holschuh 89dfc28ccb backlight: extend event support to also support poll()
Extend the backlight event support to also allow the use of
poll()/select() on actual_brightness.

We already have the entire event hookup anyway, adding a single
function call in one line to get functionality like that is a really

Matthew Garrett 325253a6b2 backlight: Allow drivers to update the core, and generate events on changes
Certain hardware will send us events when the backlight brightness
changes. Add a function to update the value in the core, and
additionally send a uevent so that userspace can pop up appropriate
UI. The uevents are flagged depending on whether the update originated
in the kernel or from userspace, making it easier to only display UI
at the appropriate time.

Mark Brown a4f3d55cb0 backlight: Add WM831x backlight driver
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.

Mario Schwalbe c78a628849 backlight: Add support for MacBook 5, MacBook Air 2, and MacBook Pro 5
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.

Ben Dooks b3b4dc8840 lcd: fix oops if driver only interested in .set_power
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.

This means if a driver only has a .set_power method then the system will
OOPS on changing mode (and with the console semaphore held so you cannot
easily see the problem).

Fix the problem by ensuring that either callback is valid before use.

Eric Miao 45e2a9b485 [ARM] pxa: fix the corgi_ssp.c dependency issue in {corgi,spitz}_defconfig
Separate building of corgi_ssp.c, and introduce a new hidden config option
CONFIG_CORGI_SSP_DEPRECATED for this. Aslo mark corgi_ts.c and corgi_bl.c
as deprecated.

This unbreaks the legacy configs in {corgi,spitz}_defconfig, however, SPI
based ADS7846 touchscreen driver and a new SPI-based corgi_lcd.c driver
with integrated backlight support are recommended.
