2006-09-27[ARM] 3847/2: Convert LOMOMO to use struct device for GPIOsRichard Purdie1-15/+15
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). Signed-off-by: Richard Purdie <rpurdie@rpsys.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2006-07-31[PATCH] fbdev: statically link the framebuffer notification functionsAntonino A. Daplas1-2/+2
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.

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.

2006-03-31[PATCH] backlight: corgi_bl: Generalise to support other Sharp SL hardwareRichard Purdie2-20/+15
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).

2006-03-31[PATCH] backlight: HP Jornada 680 Backlight driver updates/fixesRichard Purdie1-80/+59
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.

2006-03-31[PATCH] backlight: Backlight Class ImprovementsRichard Purdie2-91/+92
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.

Patch from Richard Purdie This patch moves a large chunk of the sharpsl_pm driver to arch/arm/common so that it can be reused on other devices such as the SL-5500 (collie). It also abstracts some functions from the core into the machine and platform specific parts of the driver to aid reuse.

2005-11-10[ARM] 3096/1: Add SharpSL Zaurus power and battery management core driverRichard Purdie1-0/+6
Patch from Richard Purdie This patch adds a power and battery management core driver which with the addition of the right device files, supports the c7x0 and cxx00 series of Sharp Zaurus handhelds. The driver is complex for several reasons. Battery charging is manually monitored and controlled. When suspended, the device needs to periodically partially resume, check the charging status and then re-suspend. It does without bothering the higher linux layers as a full resume and re-suspend is unnecessary. The code is carefully written to avoid interrupts or calling code outside the module under these circumstances. It also vets the various wake up sources and monitors the device's power situation. Hooks to limit the backlight intensity and to notify the battery monitoring code of backlight events are connected/added as the backlight is one of the biggest users of power on the device.

2005-11-09[PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reasonOlaf Hering2-2/+0
This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-10-28[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King1-6/+4
In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds5-0/+782
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
