backlight: add backlight type

2011-03-23T00:43:59Z

There may be multiple ways of controlling the backlight on a given machine. Allow drivers to expose the type of interface they are providing, making it possible for userspace to make appropriate policy decisions.

backlight: Allow properties to be passed at registration

2010-03-16T19:47:54Z

Values such as max_brightness should be set before backlights are registered, but the current API doesn't allow that. Add a parameter to backlight_device_register and update drivers to ensure that they set this correctly. Signed-off-by: Matthew Garrett Signed-off-by: Richard Purdie

backlight: Add backlight_device parameter to check_fb

2010-03-16T19:47:54Z

check_fb from backlight_ops lacks a reference to the backlight_device that's being referred to. Add this parameter so a backlight_device can be mapped to a single framebuffer, especially if the same driver handles multiple devices on a single system.

backlight: Revert some const qualifiers

2010-03-16T19:47:53Z

9905a43b2d563e6f89e4c63c4278ada03f2ebb14 went a little to far with const qualifiers as there are legitiment cases where the function pointers can change (machine specific setup code for example). Signed-off-by: Richard Purdie

backlight: Allow drivers to update the core, and generate events on changes

2009-09-21T20:03:58Z

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.

backlight: Add suspend/resume support to the backlight core

2009-01-08T15:37:43Z

Add suspend/resume support to the backlight core and enable use of it by appropriate drivers. Signed-off-by: Richard Purdie

backlight: Convert corgi backlight driver into a more generic driver

2007-10-11T21:24:13Z

Convert the corgi backlight driver to a more generic version so it can be reused by other code rather than being Zaurus/PXA specific. Signed-off-by: Richard Purdie

backlight: Convert from struct class_device to struct device

2007-07-16T00:20:23Z

Convert the backlight and LCD classes from struct class_device to struct device since class_device is scheduled for removal. One nasty API break is the backlight power attribute has had to be renamed to bl_power and the LCD power attribute has had to be renamed to lcd_power since the original names clash with the core. I can't see a way around this. Signed-off-by: Richard Purdie Acked-by: Greg Kroah-Hartman

backlight: Separate backlight properties from backlight ops pointers

2007-02-20T09:26:53Z

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
