From a8f340e394ff30b79ab5b03c67ab4c94b2ac3646 Mon Sep 17 00:00:00 2001

Subject: [PATCH] vt: Remove VT-specific declarations and definitions from
 tty.h

MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a
function of the VT layer than the TTY one.  Moving these to vt.h and vt_kern.h
allows all of the framebuffer and VT console drivers to remove their
dependency on tty.h.

From 894673ee6122a3ce1958e1fe096901ba5356a96b Mon Sep 17 00:00:00 2001
From: Jon Smirl <jonsmir@gmail.com>
Date: Mon, 10 Jul 2006 04:44:13 -0700
Subject: [PATCH] tty: Remove include of screen_info.h from tty.h

screen_info.h doesn't have anything to do with the tty layer and shouldn't be
included by tty.h.  This patches removes the include and modifies all users to
directly include screen_info.h.  struct screen_info is mainly used to
communicate with the console drivers in drivers/video/console.  Note that this
patch touches every arch and I have no way of testing it.  If there is a
mistake the worst thing that will happen is a compile error.

From e01af0384f54023b4548b7742952da2ffcafd4cd Mon Sep 17 00:00:00 2001
From: Michael Hanselmann <linux-kernel@hansmi.ch>
Date: Mon, 10 Jul 2006 04:44:45 -0700
Subject: [PATCH] powermac: Combined fixes for backlight code

This patch fixes several problems:
- pmac_backlight_key() is called under interrupt context, and therefore
  can't use mutexes or semaphores, so defer the backlight level for
  later, as it's not critical (original code by Aristeu S. Rozanski F.
  <aris@valeta.org>).
- Add exports for functions that might be called from modules
- Fix Kconfig depdencies on PMAC_BACKLIGHT.
- Fix locking issues on calls from inside the driver (reported by
  Aristeu S. Rozanski F., too)
- Fix wrong calculation of backlight values in some of the drivers
- Replace pmac_backlight_key_up/down by inline functions

[akpm@osdl.org: fix function prototypes]

From 22caf04297896e515c6d5cdfb8e08a79a523946c Mon Sep 17 00:00:00 2001
From: Mike Rapoport <mike@compulab.co.il>
Date: Fri, 14 Jul 2006 00:24:34 -0700
Subject: [PATCH] mbxfb: Add framebuffer driver for the Intel 2700G

Add frame buffer driver for the 2700G LCD controller present on CompuLab
CM-X270 computer module.

[adaplas]
- Add more informative help text to Kconfig
- Make DEBUG a Kconfig option as FB_MBX_DEBUG
- Remove #include mbxdebug.c, this is frowned upon
- Remove redundant casts
- Arrange #include's alphabetically
- Trivial whitespace

From 98c82472e98469ef23d7c680a0d6be1429540166 Mon Sep 17 00:00:00 2001
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Subject: [POWERPC] More offb/bootx fixes

There were still some issues with offb when BootX doesn't provide a
proper display node, this fixes them.  This also re-instates the
palette hacks that were disabled a couple of kernel versions ago when
I converted to the new OF parsing, and shuffles some functions around
to avoid prototypes.

Subject: [PATCH] fbdev: statically link the framebuffer notification functions

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.

Subject: [PATCH] radeonfb sleep fixes

Many IBM Thinkpad T4* models and some R* and X* with radeon video cards draw
too much power when suspended to RAM, reducing drastically the battery
lifetime.  The solution is to enable suspend-to-D2 on these machines.  They
are whitelisted through their subsystem vendor/device ID.  This fixes
http://bugzilla.kernel.org/show_bug.cgi?id=3022

The patch introduces a framework to alter the pm_mode and reinit_func fields
of the radeonfb_info structure based on a whitelist.  This should facilitate
future hardware-dependent workarounds.  The workaround for the Samsung P35
that is already in the radeonfb code has been rewritten using this framework.

The behavior can be overridden with module options:

i)  video=radeonfb:force_sleep=1
    enable suspend-to-D2 also on non-whitelisted machines (useful for
    testing new notebook models),

ii) video=radeonfb:ignore_devlist=1
    Disable checking the whitelist and do not apply any workarounds.

From 4b755999d6e0c1d988fb448289abb6c226cd8c36 Mon Sep 17 00:00:00 2001
From: Michael Hanselmann <linux-kernel@hansmi.ch>
Date: Sun, 30 Jul 2006 03:04:19 -0700
Subject: [PATCH] powermac: More powermac backlight fixes

This patch fixes several problems:
- The legacy backlight value might be set at interrupt time. Introduced
  a worker to prevent it from directly calling the backlight code.
- via-pmu allows the backlight to be grabbed, in which case we need to
  prevent other kernel code from changing the brightness.
- Don't send PMU requests in via-pmu-backlight when the machine is about
  to sleep or waking up.
- More Kconfig fixes.

Subject: [PATCH] nvidiafb: remove redundant CONFIG_PCI check

CONFIG_FB_NVIDIA already depends on CONFIG_PCI in drivers/video/Kconfig.
Driver does an extra ``sanity check'' which is then redundant.

Subject: [PATCH] rivafb/nvidiafb: race between register_framebuffer and
 *_bl_init

Since we now use the generic backlight infrastructure, I think we need to
call rivafb_bl_init before calling register_framebuffer since otherwise
rivafb_bl_init might race with the framebuffer layer already opening the
device and setting up the video mode.  In this case we might end up with a
not yet fully intialized backlight (info->bl_dev still NULL) when calling
riva_bl_set_power via rivafb_set_par/rivafb_load_video_mode and the kernel
dies without any further notice during boot.

This fixes booting current git on a PB 6,1.  In this case radeonfb/atyfb
would be affected too - I can fix that too but don't have any hardware to
test this on.
