[PATCH] fbdev: statically link the framebuffer notification functions

2006-07-31T20:28:44Z

The backlight and lcd subsystems can be notified by the framebuffer layer of blanking events. However, these subsystems, as a whole, can function independently from the framebuffer layer. But in order to enable to the lcd and backlight subsystems, the framebuffer has to be compiled also, effectively sucking in a huge amount of unneeded code. To prevent dependency problems, separate out the framebuffer notification mechanism from the framebuffer layer and permanently link it to the kernel.

[PATCH] spin/rwlock init cleanups

2006-06-28T00:32:39Z

locking init cleanups: - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK() - convert rwlocks in a similar manner this patch was generated automatically. Motivation: - cleanliness - lockdep needs control of lock initialization, which the open-coded variants do not give - it's also useful for -rt and for lock debugging in general Signed-off-by: Ingo Molnar Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] backlight: Fix Kconfig dependency

2006-06-26T16:58:31Z

CONFIG_FB = m and CONFIG_{BACKLIGHT:LCD}_CLASS_DEVICE = y is possible resulting in link errors. Fix by making backlight and lcd class also depend on FB Signed-off-by: Antonino Daplas Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] backlight: LOCOMO Backlight Driver updates

2006-06-26T16:58:28Z

Add backlight intensity control to the LOCOMO lcd/backlight driver using the backlight class and add basic power management support.

[PATCH] Backlight/LCD Class: Fix sysfs _store error handling

2006-05-15T18:20:56Z

The backlight and LCD class _store functions currently accept values like "34 some random strings" without error. This corrects them to return -EINVAL if the value is not numeric with an optional byte of trailing whitespace.

[PATCH] backlight: corgi_bl: Generalise to support other Sharp SL hardware

2006-03-31T20:19:00Z

Generalise the Corgi backlight driver by moving the default intensity and limit mask settings into the platform specific data structure. This enables the driver to support other Zaurus hardware, specifically the SL-6000x (Tosa) model. Also change the spinlock to a mutex (the spinlock is overkill).

[PATCH] backlight: HP Jornada 680 Backlight driver updates/fixes

2006-03-31T20:19:00Z

Updates to the HP Jornada 680 Backlight driver: - Correct the suspend/resume functions so the driver compiles (SUSPEND_POWER_DOWN/RESUME_POWER_ON no longer exist). - Convert the driver to match the recent platform device changes. - Replace the unsafe static struct platform_device with dynamic allocation. - Convert the driver to the new backlight code. This has not been tested on a device due to lack of hardware but wouldn't compile beforehand.

[PATCH] backlight: Backlight Class Improvements

2006-03-31T20:19:00Z

Backlight class attributes are currently easy to implement incorrectly. Moving certain handling into the backlight core prevents this whilst at the same time makes the drivers simpler and consistent. The following changes are included: The brightness attribute only sets and reads the brightness variable in the backlight_properties structure. The power attribute only sets and reads the power variable in the backlight_properties structure. Any framebuffer blanking events change a variable fb_blank in the backlight_properties structure. The backlight driver has only two functions to implement. One function is called when any of the above properties change (to update the backlight brightness), the second is called to return the current backlight brightness value. A new attribute "actual_brightness" is added to return this brightness as determined by the driver having combined all the above factors (and any driver/device specific factors). Additionally, the backlight core takes care of checking the maximum brightness is not exceeded and of turning off the backlight before device removal. The corgi backlight driver is updated to reflect these changes. Signed-off-by: Richard Purdie Signed-off-by: Antonino Daplas Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
