Do not limit the usage count of i2c clients to 1. In other words,
change the client usage count behavior from the old I2C_CLIENT_ALLOW_USE

[PATCH] 8xx PCMCIA: support for MPC885ADS and MPC866ADS
This adds PCMCIA support for both MPC885ADS and MPC866ADS.
This is established not together with FADS, because 885 does not have
io_block_mapping() for BCSR area.
Also, some cleanups done both for 885ADS and MBX.
[PATCH] pcmcia: properly handle static mem, but dynamic io sockets
Some PCMCIA sockets have statically mapped memory windows, but dynamically
mapped IO windows. Using the "nonstatic" socket library is inpractical for
them, as they do neither need a resource database (as we can trust the
kernel resource database on m68k and ppc) nor lots of other features of that
library. Let them get a small "iodyn" socket library (105 lines of code)
instead.
[PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe callback
Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified
probe() callback. As all in-kernel drivers are changed to this new
callback, there will be no temporary backwards-compatibility. Inside a
probe() function, each driver _must_ set struct pcmcia_device
*p_dev->instance and instance->handle correctly.
With these patches, the basic driver interface for 16-bit PCMCIA drivers
now has the classic four callbacks known also from other buses:
int (*probe) (struct pcmcia_device *dev);
void (*remove) (struct pcmcia_device *dev);
int (*suspend) (struct pcmcia_device *dev);
int (*resume) (struct pcmcia_device *dev);
Move the suspend and resume methods out of the event handler, and into
special functions. Also use these functions for pre- and post-reset, as
almost all drivers already do, and the remaining ones can easily be
converted.

[ATYFB]: Fix onboard video on SPARC Blade 100 for 2.6.{13,14,15}
I have recently been switching from using 2.4.32 on my trusty
old Sparc Blade 100 to using 2.6.15 . Some of the problems I ran into
were distorted video when the console was active (missing first
character, skipped dots) and when running X windows (colored snow,
stripes, missing pixels). A quick examination of the 2.6 versus 2.4
source for the ATY driver revealed alot of changes.
A closer look at the code/data for the 64GR/XL chip revealed
two minor "typos" that the rewriter(s) of the code made. The first is
a incorrect clock value (230 .vs. 235) and the second is a missing
flag (M64F_SDRAM_MAGIC_PLL). Making both these changes seems to have
fixed my problem. I tend to think the 235 value is the correct one,
as there is a 29.4 Mhz clock crystal close to the video chip and 235.2
(29.4*8) is too close to 235 to make it a coincidence.
The flag for M64F_SDRAM_MAGIC_PLL was dropped during the
changes made by adaplas in file revision 1.72 on the old bitkeeper
repository.
The change relating to the clock rate has been there forever,
at least in the 2.6 tree. I'm not sure where to look for the old 2.5
tree or if anyone cares when it happened.
On SPARC Blades 100's, which use the ATY MACH64GR video chipset, the
clock crystal frequency is 235.2 Mhz, not 230 Mhz. The chipset also
requires the use of M64F_SDRAM_MAGIC_PLL in order to setup the PLL
properly for the DRAM.

Add MODULE_ALIAS to IDE midlayer modules: ide-disk, ide-cd, ide-floppy and
ide-tape, to autoload these modules depending on the probed media type of
the IDE device.
It is used by udev and replaces the former agent shell script of the hotplug
package, which was required to lookup the media type in the proc filesystem.
Using proc was racy, cause the media file is created after the hotplug event
is sent out.
The module autoloading does not take any effect, until something like the
following udev rule is configured:
SUBSYSTEM=="ide", ACTION=="add", ENV{MODALIAS}=="?*", RUN+="/sbin/modprobe $env{MODALIAS}"
The module ide-scsi will not be autoloaded, cause it requires manual
configuration. It can't be, and never was supported for automatic setup in
the hotplug package. Adding a MODULE_ALIAS to ide-scsi for all supported
media types, would just lead to a default blacklist entry anyway.
