b0e3636f65 Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger:
 "Things have been quiet this round with mostly bugfixes, percpu
  conversions, and other minor iscsi-target conformance testing changes.

  The highlights include:

   - Add demo_mode_discovery attribute for iscsi-target (Thomas)
   - Convert tcm_fc(FCoE) to use percpu-ida pre-allocation
   - Add send completion interrupt coalescing for ib_isert
   - Convert target-core to use percpu-refcounting for se_lun
   - Fix mutex_trylock usage bug in iscsit_increment_maxcmdsn
   - tcm_loop updates (Hannes)
   - target-core ALUA cleanups + prep for v3.14 SCSI Referrals support (Hannes)

  v3.14 is currently shaping to be a busy development cycle in target
  land, with initial support for T10 Referrals and T10 DIF currently on
  the roadmap"

8ceafbfa91 Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm
Pull DMA mask updates from Russell King:
 "This series cleans up the handling of DMA masks in a lot of drivers,
  fixing some bugs as we go.

  Some of the more serious errors include:
   - drivers which only set their coherent DMA mask if the attempt to
     set the streaming mask fails.
   - drivers which test for a NULL dma mask pointer, and then set the
     dma mask pointer to a location in their module .data section -
     which will cause problems if the module is reloaded.

  To counter these, I have introduced two helper functions:
   - dma_set_mask_and_coherent() takes care of setting both the
     streaming and coherent masks at the same time, with the correct
     error handling as specified by the API.
   - dma_coerce_mask_and_coherent() which resolves the problem of
     drivers forcefully setting DMA masks.  This is more a marker for
     future work to further clean these locations up - the code which
     creates the devices really should be initialising these, but to fix
     that in one go along with this change could potentially be very
     disruptive.

  The last thing this series does is prise away some of Linux's addition
  to "DMA addresses are physical addresses and RAM always starts at
  zero".  We have ARM LPAE systems where all system memory is above 4GB
  physical, hence having DMA masks interpreted by (eg) the block layers
  as describing physical addresses in the range 0..DMAMASK fails on
  these platforms.  Santosh Shilimkar addresses this in this series; the
  patches were copied to the appropriate people multiple times but were
  ignored.

  Fixing this also gets rid of some ARM weirdness in the setup of the
  max*pfn variables, and brings ARM into line with every other Linux
  architecture as far as those go"

f9efbce633 ARM: SoC DT updates for 3.13
Most of this branch consists of updates, additions and general churn of
 the device tree source files in the kernel (arch/arm/boot/dts). Besides
 that, there are a few things to point out:
 
 - Lots of platform conversion on OMAP2+, with removal of old board files
   for various platforms.
 - Final conversion of a bunch of ux500 (ST-Ericsson) platforms as well
 - Some updates to pinctrl and other subsystems. Most of these are for
   DT-enablement of the various platforms and acks have been collected.

aac59e3efc ARM: SoC platform changes for 3.13
New and updated SoC support. Among the things new for this release are:
 
 - More support for the AM33xx platforms from TI
 - Tegra 124 support, and some updates to older tegra families as well
 - imx cleanups and updates across the board
 - A rename of Broadcom's Mobile platforms which were introduced as ARCH_BCM,
   and turned out to be too broad a name. New name is ARCH_BCM_MOBILE.
 - A whole bunch of updates and fixes for integrator, making the platform code
   more modern and switches over to DT-only booting.
 - Support for two new Renesas shmobile chipsets. Next up for them is more work
   on consolidation instead of introduction of new non-multiplatform SoCs, we're
   all looking forward to that!
 - Misc cleanups for older Samsung platforms, some Allwinner updates, etc.

Pull ARM SoC platform changes from Olof Johansson:
 "New and updated SoC support.  Among the things new for this release
  are:

   - More support for the AM33xx platforms from TI
   - Tegra 124 support, and some updates to older tegra families as well
   - imx cleanups and updates across the board
   - A rename of Broadcom's Mobile platforms which were introduced as
     ARCH_BCM, and turned out to be too broad a name.  New name is
     ARCH_BCM_MOBILE.
   - A whole bunch of updates and fixes for integrator, making the
     platform code more modern and switches over to DT-only booting.
   - Support for two new Renesas shmobile chipsets.  Next up for them is
     more work on consolidation instead of introduction of new
     non-multiplatform SoCs, we're all looking forward to that!
   - Misc cleanups for older Samsung platforms, some Allwinner updates,
     etc"

The AT91 PMC (Power Management Controller) provides a USB clock used by
the different USB controllers (ehci, ohci and udc).
The atmel-ehci driver must configure the usb clock rate to 48Mhz in order
to get a fully functionnal USB host controller.
This configuration was formely done in mach-at91/clock.c, but will be
bypassed when moving to common clk framework.

This patch adds support for usb clock retrieval and configuration only if
CCF is enabled (CONFIG_COMMON_CLK).

9983d6dc4e usb: cdc-wdm: ignore speed change notifications
The only notification supported by the Device Management class is
Response Available. But this driver is also used as a subdriver of
other CDC classes, allowing notifications like Speed Change and
Network Connection. This results in log messages which are only
confusing to an end user:

 [66255.801874] cdc_mbim 1-3:1.5: unknown notification 42 received: index 5 len 8

These drivers use cdc-wdm as a subdriver to allow access to an
embedded management protocol, and all management is expected to
use this protocol. There is therefore no need to handle any of
these optional CDC notifications. Instead we can let the cdc-wdm
driver recognize them and log a debug level message instead of an
error.

df101c531e usb: chipidea: host: more enhancement when ci->hcd is NULL
Like http://marc.info/?l=linux-usb&m=138200449428874&w=2 said:
two more things are needed to be done:

- If host_start fails, the host_stop should not be called, so we
add check that ci->hcd is not NULL.
- if the host_start fails at the beginning, we need to consider
regulator mismatch issue.

e55f7cd246 usb: ohci: remove ep93xx bus glue platform driver
Convert ep93xx to use the OHCI platform driver and remove the
ohci-ep93xx bus glue driver.

Enable CONFIG_OHCI_HCD_PLATFORM in the ep93xx_defconfig so that USB
is still enabled by default on the EP93xx platform.
