Richard Purdie 599a52d126 backlight: Separate backlight properties from backlight ops pointers
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.

Richard Purdie dfcba20067 backlight: Remove unneeded owner field
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>

Henrique de Moraes Holschuh 4437cd1e98 [PATCH] backlight: do not power off backlight when unregistering
ACPI drivers like ibm-acpi are moving to the backlight sysfs
infrastructure.  During ibm-acpi testing, I have noticed that
backlight_device_unregister() sets the display brightness and power to
zero.

This causes the display to be dimmed on ibm-acpi module removal.  It will
affect all other ACPI drivers that are being converted to use the backlight
class, as well.  It also affects a number of framebuffer devices that are
used on desktops and laptops which might also not want such behaviour.

Since working around this behaviour requires undesireable hacks, Richard
Purdie decided that we would be better off reverting the changes in the
sysfs class, and adding the code to dim and power off the backlight device
to the drivers that want it.  This patch is my attempt to do so.

Patch against latest linux-2.6.git.  Changes untested, as I lack the
required hardware.  Still, they are trivial enough that, apart from typos,
there is little chance of getting them wrong.

Richard Purdie 8d48427ecb [ARM] 3847/2: Convert LOMOMO to use struct device for GPIOs
Convert LOMOMO to use struct device * for GPIOs instead of struct
locomo_dev. This enables access to the GPIOs from code which is not
a locomo device itself (such as audio). Access for gpio 31 is removed
for error handling (no such hardware exists).

Pavel Machek 987132bb0b [PATCH] Support powering sharp zaurus sl-5500 LCD up and down
This adds support for powering Zaurus's video up and down.  PDA without
screen is kind of useless, so it is quite important...  I'll have to figure
out how to really control the frontlight, because LCD without that is quite
hard to read.
