Merge tag 'v3.4-rc2' into for-3.5

Linux 3.4-rc2 contains some bug fixes we need, including the addition of
an export for regcache_sync_region().

8f549d7e77 ASoC: fsl: remove helper fsl_asoc_get_codec_dev_name
The ASoC core now can support matching codec with device node besides
name, so we can save helper function fsl_asoc_get_codec_dev_name.

60aae8da29 ASoC: fsl: create fsl_utils to accommodate the common functions
There is some amount of code duplication between mpc8610_hpcd and
p1022_ds machine drivers, and the same code will be duplicated again
when another new machine driver is added.  The patch creates fsl_utils
to accommodate the common functions to stop the code duplication.

9cb6abcb26 powerpc/8xxx: remove 85xx/86xx restrictions from fsl_guts.h
Remove the check for CONFIG_PPC_85xx and CONFIG_PPC_86xx from fsl_guts.h.
The check was originally intended to allow the same header file to
be used on 85xx and 86xx systems, even though the Global Utilities
register could be different.  It turns out that they're not actually
different, and so the check is not necessary.  In addition, neither
macro is defined for 64-bit e5500 kernels, so that causes a build
break.

70ac07bb63 ASoC: fsl: p1022ds: tell the WM8776 codec driver that it's the master
The WM8776 codec driver requires the machine driver to set one of the
SND_SOC_DAIFMT_CBx_xxx values.  The P1022DS machine driver should be setting
SND_SOC_DAIFMT_CBM_CFM, but since that value was zero, no one noticed.

Commit 75d9ac46 ("ASoC: Allow DAI formats to be specified in the
dai_link"), however, changed the value of SND_SOC_DAIFMT_CBM_CFM from zero
to a non-zero value, which means that it now needs to be specifically set
by the machine driver.

We also set SND_SOC_DAIFMT_NB_NF, for the same reason.

2b81ec6914 ASoC: fsl: check property 'compatible' for the machine name
Check /compatible rather than /model to determine the machine name.
The p1022ds older device trees get a different /model from the new
ones, while /compatible is consistent there, so checking /compatible
will save the bother of detecting older p1022ds device trees.

6132725eac ASoC: fsl/powerpc: don't rely on the cell-index property
Instead of using the 'cell-index' property in the I2C adapter node to
determine the adapter number, just query the i2c_adapter object directly.

Previously, the I2C nodes always appeared in cell-index order, so the
dynamic numbering coincided with the cell-index property.  With commit
ab827d97 ("powerpc/85xx: Rework P1022DS device tree"), the I2C nodes are
unintentionally reversed in the device tree, and so the machine driver
guesses the wrong I2C adapter number.

a806aa9207 ASoC: p1022ds: add support for fsl,P1022 and fsl,P1022DS model names
Commit ab827d97 ("powerpc/85xx: Rework P1022DS device tree") renamed the
the /model property of the P1022DS device tree from "fsl,P1022" to
"fsl,P1022DS".  To support both old and new device trees, the ASoC
machine driver for the P1022DS needs to query the /model property and
update the platform driver object dynamically.

147dfe90f7 ASoC: p1022ds: fix incorrect referencing of device tree properties
Device tree integer properties are encoded in big-endian format, but some of
the Freescale ASoC drivers were assuming that the host is in big-endian format
as well.  Although this is true, it's better to use endian-safe accessors.

Also add a check for a failed ioremap() call in the SSI driver.

880b8ffd45 ASoC: pl022_ds.c: Add of_node_put to avoid memory leak
Add a call to of_node_put in the error handling code following a call to
of_parse_phandle.

This patch also moves the existing call to of_node_put tothe end of the
error handling code, to make it possible to jump to of_node_put without
doing the other cleanup operations.  These appear to be disjoint
operations, so the ordering doesn't matter.
