Any non-standard property should contain the vendor's identifier which
should be perpended onto the property name followed by a comma. This
aids in name-space collision prevention.

Any non-standard property should contain the vendor's identifier which
should be perpended onto the property name followed by a comma. This
aids in name-space collision prevention. This patch ensures the
sleepmode property adheres to the rules.

The AB8500 driver has now been provided with IRQ domain support. This
means we can request IRQs from any of it's uses via Device Tree. This
patch advertises the AB8500 as an Interrupt Controller and provides the
correct calls in the format the driver expects.

Code exists in the mop500 board file (used for HREF and Snowball)

This patch provides a way for find_clk() to complete its name-based

different naming structure to that of more traditional initialisation
methods, find_clk() not succeed without these bindings.

Now that u5500 is obsolete, u8500 is the only user of the Nomadik
i2c driver. As such there is no requirement to differentiate between
initialisation values. By the time a new SoC is released, almost all
of the ux500 platform will be DT:ed, so we can make decisions based
on the compatible property instead.

The rework of the snd-usb endpoint logic moved the calls to
snd_usb_set_interface() into the snd_usb_endpoint implemenation. This
changed the order in which these calls are issued to the device, and
thereby caused regressions for some webcams.
Fix this by moving the calls back to pcm.c for now to make it work again
and use snd_usb_endpoint_activate() to really tear down all remaining
URBs in the flight, consequently fixing another regression caused by USB
packets on the wire after altsetting 0 has been selected.

Commit 4972a80e16a2 (ARM: SAMSUNG: Add device tree support for pl330 dma
engine wrappers) introduced a new member 'dt_dmach_prop' in the struct
samsung_dma_info which is used to specify the dma channel number property
as obtained from the device tree. It also introduced a new dma request id
'DMACH_DT_PROP' to indicate that a device tree node property represting
the dma channel is available in 'struct samsung_dma_info'.
Add dma request id 'DMACH_DT_PROP' in s3c64xx dma channel id list in order
to maintain compatibility to the changes in the Samsung dma wrappper
operations.

Make it easier to switch to the common clock API by making the existing
clock API implementation depend on a Kconfig symbol which is enabled when
the common clock API is disabled. This means that we can have some SoCs
using the common clock API and some using the existing API rather than
needing a flag day to convert the entire family of devices over.

The power/async device sysfs attribute is only used if both
CONFIG_PM_ADVANCED_DEBUG and CONFIG_PM_SLEEP are set, but the code
implementing it doesn't depend on CONFIG_PM_SLEEP. As a result, a

CONFIG_PM_SLEEP is not set.
Fix it by adding a #ifdef CONFIG_PM_SLEEP around the code in

Commit d640113fe80e45ebd4a5b420b introduced a regression on SMP
systems where the processor core with ACPI id zero is disabled
(typically should be the case because of hyperthreading).
The regression got spread through stable kernels.
On 3.0.X it got introduced via 3.0.18.
Such platforms may be rare, but do exist.
Look out for a disabled processor with acpi_id 0 in dmesg:
ACPI: LAPIC (acpi_id[0x00] lapic_id[0x10] disabled)
This problem has been observed on a:
HP Proliant BL280c G6 blade

In commit a7959c1, the USB part of rtlwifi was switched to convert
_usb_read_sync() to using a preallocated buffer rather than one
that has been acquired using kmalloc. Although this routine is named
as though it were synchronous, there seem to be simultaneous users,
and the selection of the index to the data buffer is not multi-user
safe. This situation is addressed by adding a new spinlock. The routine
cannot sleep, thus a mutex is not allowed.
