two reasons:
1. GPIO namings and their mode definitions are conceptually not part
of the PXA register definitions2. this is actually a temporary move in the transition of PXA2xx to
use MFP-alike APIs (as what PXA3xx is now doing), so that legacy
code will still work and new code can be added in step by stepSigned-off-by: eric miao

This fixes the builtin RTL8139 NIC on the Medion MD9580-F laptop. The
BIOS reports the interrupt routing incorrectly. I recently added a
quirk to work around this, and this patch fixes a typo in the quirk.We pad every ACPI pathname component to four characters, so ".ISA." will
never match anything. We need ".ISA_." instead.Thank you Johann-Nikolaus Andreae
for patiently testing this patch.See http://bugzilla.kernel.org/show_bug.cgi?id=4773

lockdep goes off on the iova copy_reserved_iova() because it and a function
it calls grabs locks in the from, and the to of the copy operation.The function grab locks of the same lock classes triggering the warning. The
first lock grabbed is for the constant reserved areas that is never accessed
after early boot. Technically you could do without grabbing the locks for the
"from" structure its copying reserved areas from.But dropping the from locks to me looks wrong, even though it would be ok.
The affected code only runs in early boot as its setting up the DMAR
engines.This patch gives the reserved_ioval_list locks special lockdep classes.

The VIA VT6212 defaults to only waiting 1us between passes over EHCI's
async ring, which hammers PCI badly ... and by preventing other devices
from accessing the bus, causes problems like drops in IDE throughput,
a problem that's been bugging users of those chips for several years.A (partial) datasheet for this chip eventually turned up, letting us
see how to make it use a VIA-specific register to switch over to the
the normal 10us value instead, as suggested by the EHCI specification
Solution noted by Lev A. Melnikovsky.It's not clear whether this register exists on other VIA chips; we
know that it's ineffective on the vt8235. So this patch only applies
to chips that seem to be incarnations of the (discrete) vt6212.Signed-off-by: Rene Herman

A Promise SATA controller will signal hotplug events when a hard
reset (COMRESET) is done on a port. These events aren't masked by
the driver, and the unexpected interrupts will cause a sequence
of failed reset attempts util libata's EH finally gives up.This has not been a common problem so far, but the pending libata
hardreset-by-default changes makes it a critical issue.The solution is to disable hotplug events before a reset, and to
reenable them afterwards. (Promise's driver does this too.)This patch adds SATA-specific versions of ->freeze() and ->thaw()
that also disable and enable hotplug events. PATA ports continue
to use the old versions of ->freeze() and ->thaw().Accesses to the hotplug register must be serialised via host->lock.
We rely on ap->lock == &ap->host->lock and that libata takes this
lock before ->freeze() and ->thaw(). Document this requirement.
The interrupt handler is adjusted so its hotplug register accesses
are inside the region protected by host->lock.Tested on various chips (SATA300TX4, SATA300TX2plus, SATAII150TX4,
FastTrack TX4000) with various combinations of SATA and PATA disks,
with and without the pending hardreset-by-default changes.Signed-off-by: Mikael Pettersson

Update documentation for the hw_random support to be current:
- Documentation/hw_random.txt has been updated to reflect the
current code: it's a framework now, a "core" with a small
sysfs interface, that hardware-specific drivers plug in to.
Text specific to Intel hardware is now at the end.- Kconfig now references the Documentation/hw_random.txt file
and better explains what this really does.Both chunks of documentation now higlight the fact that the kernel entropy
pool is maintained by "rngd", and this driver has nothing directly to do with
that important task.Signed-off-by: David Brownell

There's no point in retrying and eventually failing device detection

This is to fix bugzilla #10254. QSI cdrom attached to pata_sis as
secondary master appears as phantom device for the slave.
Interestingly, instead of not setting DRQ after IDENTIFY which
triggers NODEV_HINT, it aborts both IDENTIFY and IDENTIFY PACKET which
makes EH retry.Modify EH such that it assumes no device is attached if both flavors
of IDENTIFY are aborted by the device. There really isn't much point
in retrying when the device actively aborts the commands.While at it, convert NODEV detection message to ata_dev_printk() to
help debugging obscure detection problems.This problem was reported by Jan Bücken.

If an I2C interrupt happens between disabling interface clock
and functional clock, the interrupt handler will produce an
external abort on non-linefetch error when trying to access
driver registers while interface clock is disabled.This patch fixes the problem by saving and disabling i2c-omap
interrupt before turning off the clocks. Also disable functional
clock before the interface clock as suggested by Paul Walmsley.Patch also renames enable/disable_clocks functions to unidle/idle
functions. Note that the driver is currently not taking advantage
of the idle interrupts. To use the idle interrupts, driver would
have to enable interface clock based on the idle interrupt
and dev->idle flag.This patch has been tested in linux-omap tree with various omaps.
