The register definitions have been changed for the mpc5200 PSC ports
to cover some of the changes in the mpc5200b. One change is that the
ccr register is now a u32 instead of a u16. However, for the purposes
of this driver we want to continue to use 16 bit access to avoid
changing the existing (working) behaviour.
This patch allows the driver to continue to do 16 bit accesses without
the compiler complaining about it.

The PowerPC 405EZ SoC has some differences in the interrupt layout and
handling for the MAL. The SERR, TXDE, and RXDE interrupts are OR'd into
a single interrupt. Also, due to the possibility for interrupt coalescing,
the TXEOB and RXEOB interrupts require an interrupt bit to be cleared in
the ICINTSTAT SDR.
This sets the proper MAL feature bits for 405EZ boards, and adds a common
shared handler for SERR, TXDE, and RXDE. The defines for the ICINTSTAT DCR
are added to the proper header file as well.
This has been adapted from code originally written by Stefan Roese.

There are some PowerPC SoCs that do odd things with the MAL handling. In
order to accommodate them, we need to introduce a feature mechanism that is
similar to the existing emac_has_feature function.
This adds a feature variable to the mal_instance structure, and adds a
mal_has_feature function. Two features are defined and are guarded
by Kconfig options that are selected by the affected platforms.
MAL_FTR_CLEAR_ICINSTAT is used for platforms that need to clear the
interrupt bits in the ICINTSTAT SDR for txeob/rxeob. This is common
on MAL implementations that have interrupt coalescing.
MAL_FTR_COMMON_ERR_INT is used for platforms that have SERR, TXDE,
and RXDE OR'd into a single interrupt bit.

Some PowerPC 40x chips have errata that force us not to use the integrated
flow control. We have the feature defined, but it currently can't be used
because it is never added to EMAC_FTRS_POSSIBLE.
This adds a Kconfig option for affected platforms to select and puts the
feature in the EMAC_FTRS_POSSIBLE list. This is set for PowerPC 405EZ
platforms as well.

On HSM_ST_ERR, ata_hsm_move() triggers WARN_ON() if AC_ERR_DEV or
AC_ERR_HSM is not set. PHY events may trigger HSM_ST_ERR with other
error codes and, with or without it, there just isn't much reason to
do WARN_ON() on it. Even if error code is not set there, core EH
logic won't have any problem dealing with the error condition.

of them being unifying probing, hotplug and EH reset paths uniform.
Previously, broken hardreset could go unnoticed as it wasn't used
during probing but when something goes wrong or after hotplug the
problem will surface and bite hard.
OSDL bug 11195 reports that sata_nv generic flavor falls into this
category. Hardreset itself succeeds but PHY stays offline after
hardreset. I tried longer debounce timing but the result was the
same.
http://bugzilla.kernel.org/show_bug.cgi?id=11195
So, it seems we'll have to drop hardreset from the generic flavor.

I've been chasing Jeff about this for months. Jeff added the Marvell
device identifiers to the ahci driver without making the AHCI driver
handle the PATA port. This means a lot of users can't use current
kernels and in most distro cases can't even install.
This has been going on since March 2008 for the 6121 Marvell, and late 2007
for the 6145!!!
This was all pointed out at the time and repeatedly ignored. Bugs assigned
to Jeff about this are ignored also.
To quote Jeff in email
> "Just switch the order of 'ahci' and 'pata_marvell' in
> /etc/modprobe.conf, then use Fedora's tools regenerate the initrd.
> See? It's not rocket science, and the current configuration can be
> easily made to work for Fedora users."
(Which isn't trivial, isn't end user, shouldn't be needed, and as it usually
breaks at install time is in fact impossible)
To quote Jeff in August 2007
> " mv-ahci-pata
> Marvell 6121/6141 PATA support. Needs fixing in the 'PATA controller
> command' area before it is usable, and can go upstream."
Only he add the ids anyway later and caused regressions, adding a further
id in March causing more regresions.
The actual fix for the moment is very simple. If the user has included
the pata_marvell driver let it drive the ports. If they've only selected
for SATA support give them the AHCI driver which will run the port a fraction
faster. Allow the user to control this decision via ahci.marvell_enable as
a module parameter so that distributions can ship 'it works' defaults and
smarter users (or config tools) can then flip it over it desired.

The current check for monotonicity is way too weak: Andreas Mohr reports (
http://lkml.org/lkml/2008/8/10/77 ) that on one of his test systems the
current check only triggers in 50% of all cases, leading to catastrophic
timer behaviour. To fix this issue, expand the check for monotonicity by
doing ten consecutive tests instead of one.

On all hardware (some Intel ICH4, PIIX4 and PIIX4E chipsets) affected by a
hardware errata there's about a 4.2% chance that initialization of the
ACPI PMTMR fails. On those chipsets, we need to read out the timer value
at least three times to get a correct result, for every once in a while
(i.e. within a 3 ns window every 69.8 ns) the read returns a bogus
result. During normal operation we work around this issue, but during
initialization reading a bogus value may lead to -EINVAL even though the
hardware is usable.
Thanks to Andreas Mohr for spotting this issue.

Fix offset of second word used for programming base address of memory
window. Also program tmio with offset of the FCR, not with physical
memory location.

This patch teaches the i2c-sh_mobile driver to make use of wait irqs.
Without this patch only dte irqs are used which may lead to overruns
and cases of missing stop and extra bytes being read on the i2c bus.
Use of wait irqs forces the hardware to pause and wait until the cpu
is ready. Polling is also reworked in this patch to fix ms delay issues.
Verified with bus analyzer and tested on MigoR and AP325RXA boards.

Apparently, there are more different versions of Lenovo 3000 N100, some
of them working properly with active mux, and some of them requiring it
being switched off.
This patch applies 'nomux' only to the specific product name that is
reported to behave badly unless 'nomux' is specified.

The mousedev driver requires the use of BTN_TOUCH events to process
ABS_X and ABS_Y events properly, which is what is needed for the
bcm5974-based apple computers to have a functional pointer out-of-the-box.

The problem of finger tracking, i.e., when to switch focus from one
finger to another on the trackpad, has been improved by utilizing more
information from the bcm5974 chip output. This results in less pointer
hopping when many fingers are on the trackpad. In addition, a finger
counting method based on pressure information from all fingers is
introduced. Together with a pressure hysteresis window, this yields a
more stable counting of the number of fingers on the trackpad.

While doing some testing using Luca Risolia's sonix driver I noticed that
the video device did not get ACL's set to allow access by locally logged in
users, nor does it show up as a video device in lshal, causing cheese to not
see it.
This turns out to be caused by all of Luca Risolia's drivers not setting
the parent member of the video_device struct. This patch fixes this.

b2c2-flexcop, dvb/bt8xx and video/bt8xx fails to build on ARM with:
__bad_udelay is specifically designed on ARM to fail when udelay is
called in a bad way. arch/arm/include/asm/delay.h has this to say
about __bad_udelay:
/*
* This function intentionally does not exist; if you see references to
* it, it means that you're calling udelay() with an out of range value.
*
* With currently imposed limits, this means that we support a max delay
* of 2000us. Further limits: HZ<=1000 and bogomips<=3355
*/
extern void __bad_udelay(void);
Solution is to replace udelay by a mdelay and udelay with value less than 2000

- Adjust hstart in ov7630 on sn9c103 initdata to shift bayer pattern, this is
the same change as done for the other initdata tables in a previous patch.
- Assign usb-id's for the ov7630 + sn9c103 to gspca if gspca and sn9c102
drivers are both enabled.
