Pull PTR_RET() removal patches from Rusty Russell:
"PTR_RET() is a weird name, and led to some confusing usage. We ended
up with PTR_ERR_OR_ZERO(), and replacing or fixing all the usages.
This has been sitting in linux-next for a whole cycle"
[ There are still some PTR_RET users scattered about, with some of them
possibly being new, but most of them existing in Rusty's tree too. We
have that
#define PTR_RET(p) PTR_ERR_OR_ZERO(p)
thing in <linux/err.h>, so they continue to work for now - Linus ]

Pull sound updates from Takashi Iwai:
"Changes are seen in a wide range of codes, mainly due to ASoC DAPM
requirements; HD-audio shows a high peak in diffstat, it's just a
removal of bunch of old static quirks.
Some highlights:
- HDPM: Updates for AIO/RayDAT support, TCO/sync support
- RME96: Add PCM sync support
- HD-audio:
* A few HDMI/DP audio updates (CA assignment fix, stream switching
fix, Intel DP device list support)
* Device specific fixes (ASUS/CXT HP mic support, Thinkpad mic
improvements, Chromebook fixes, STAC9228 Dell fixes)
* Replace the all static quirks for AD codecs with the generic
parser
* WAKEEN support for handling irqs in the power saving mode
- USB-audio: Clean up implicit fb handling and related codes
- DAPM is now mandatory for ASoC CODEC drivers; all existing drivers
have had some level of DAPM support added. In addition, a lot of
cleanups and improvements in DAPM.
- Support for ASoC cross-platform compile test
- New drivers and support for Analog Devices ADAU1702 and
ADAU1401(a), Asahi Kasei Microdevices AK4554, Atmel AT91ASM9x5 and
WM8904 based machines, Freescale S/PDIF and SSI AC'97, Renesas
R-Car SoCs, Samsung Exynos5420 SoCs, Texas Instruments PCM1681 and
PCM1792A and Wolfson Microelectronics WM8997
- DT bindings for kirkwood and i.MX S/PDIF
- Clean up and bug fixes: ssm2602, rt5640 and sgtl5000.
- Core helpers for bitbanged AC'97 reset"

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control changes from Linus Walleij:
"Here is the bulk of pin control changes for the v3.12 series. Most of
the relevant information is in the tag.
I merged in v3.11-rc7 last week to get rid of a largeish conflict
within the sunxi (AllWinner) driver in linux-next and fix up the
non-trivial merge the right way. That driver had a rather large fix
adding locking late in the release cycle.
Overall the bulk changes this time is cleanups and refactorings and
not much new features, which is nice.
- Refactorings for generic pin config handling in the core.
- Factor out a set of device tree utilities for use in all drivers,
to parse and allocate maps from the device tree.
- Some fixes to the core such as more nitpicky locking.
- Pushed down config array iteration into the drivers.
This patch is necessary for drivers that want to iterate over
configs and pile up a stack of alterations to the same register(s),
or if the driver wants to take a local spinlock when committing the
configuration.
- A new driver for the Texas Instruments Palmas PMIC by Laxman
Dewangan. This is used on the Tegra systems.
- A major cleanup and modernization of the PFC (Super Hitachi and ARM
SHmobile) pin controller and subdrivers.
- Support for the A20 and A31 sunxi (AllWinner) SoCs.
- A huge pile of fixes and cleanups: Axel Lin, Jingoo Han Dan
Carpenter, Julia Lawall and Sachin Kamat did an excellent job here"

The legacy S3C-DMA API required every period of a cyclic buffer to be
queued separately. After conversion of Samsung ASoC to Samsung DMA
wrappers somebody made an assumption that the same is needed for DMA
engine API, which is not true.
In effect, Samsung ASoC DMA code was queuing the whole cyclic buffer
multiple times with a shift of one period per iteration, leading to:
a) severe memory waste - up to 13x times more DMA transfer descriptors
are allocated than needed,
b) possible memory corruption, because further cyclic buffers were out
of the original buffers, due to the offset.
This patch fixes this problem by making the legacy S3C-DMA API use the
same semantics as DMA engine (the whole cyclic buffer is enqueued at
once) and modifying users of Samsung DMA wrappers in cyclic mode to
behave appropriately.

Let's follow the ratified DT binding and use uartdm instead of
hsuart. This does break backwards compatibility but this
shouldn't be a problem because the uart driver isn't probing on

In downstream kernel we've standardized the clock consumer names
that MSM device drivers use. Replace the uart specific clock
names in this driver with the more standard 'core' and 'iface'
names. Also simplify the code by assuming that clk_prepare_enable
and clk_disable_unprepare() will properly check for NULL pointers
(it will because MSM uses the common clock framework).

the micro USB connector had an USB-UART there. I was wrong a little. The
second port runs on host mode, but the micro USB plug is connected to an
internal HUB with two ports: one to the USB-UART and one to musb
instance one.
For that reason, this patch enables both ports: the primary in device
mode only and the second in host mode only.

This is what I observe:
On the first connect, the musb starts with DEVCTL.Session set. On
disconnect, musb_core calls try_idle. That functions removes the Session
bit signalizing that the session is over (something that only in OTG is
required). A new device, that is plugged, is no longer recognized.
I've setup a timer and checked the DEVCTL register and I haven't seen a
change in VBus and I saw the B-Device bit set. After setting the IDDIG
into A mode and forcing the device to behave like a A device, I didn't
see a change.
Neither VBUS goes to 0b11 nor does a session start request comes.
In the TI-v3.2 kernel they skip to call musb_platform_try_idle() in the
OTG_STATE_A_WAIT_BCON state while not in OTG mode.
Since the second port hast a standard A plug the patch changes the port
to run in host mode only and skips the timer which would remove
DEVCTL.Session so we can reconnect to another device later.

This relfects the code and dts requires changes due to recent .dts
binding updates:
- use mg prefix for the Metor Graphics specific attributes
- use power in mA not in mA/2 as specifed in the USB2.0 specification
- remove the child node for USB. This is driver specific on won't be
reflected in the device tree
- use the "mentor" prefix instead of "mg".
- use "dr_mode" istead of "mg,port-mode" for the port mode. The former
is used by a few other drivers.

I forgot to separete the different names in the reg-names property. This
didn't cause anything to fail because the driver does not use the names
and simply relies on the order of the memory offsets in reg.
This patch fixes this in case it is used later.

This fixes a regression exposed during the merge window by commit
9f310de "ARM: tegra: fix VBUS regulator GPIO polarity in DT"; namely that
USB VBUS doesn't get turned on, so USB devices are not detected. This
affects the internal USB port on TrimSlice (i.e. the USB->SATA bridge, to
which the SSD is connected) and the external port(s) on Seaboard/
Springbank and Whistler.
The Tegra DT as written in v3.11 allows two paths to enable USB VBUS:
1) Via the legacy DT binding for the USB controller; it can directly
acquire a VBUS GPIO and activate it.
2) Via a regulator for VBUS, which is referenced by the new DT binding
for the USB controller.
Those two methods both use the same GPIO, and hence whichever of the
USB controller and regulator gets probed first ends up owning the GPIO.
In practice, the USB driver only supports path (1) above, since the
patches to support the new USB binding are not present until v3.12:-(
In practice, the regulator ends up being probed first and owning the
GPIO. Since nothing enables the regulator (the USB driver code is not
yet present), the regulator ends up being turned off. This originally
caused no problem, because the polarity in the regulator definition was
incorrect, so attempting to turn off the regulator actually turned it
on, and everything worked:-(
However, when testing the new USB driver code in v3.12, I noticed the
incorrect polarity and fixed it in commit 9f310de "ARM: tegra: fix VBUS
regulator GPIO polarity in DT". In the context of v3.11, this patch then
caused the USB VBUS to actually turn off, which broke USB ports with VBUS
control. I got this patch included in v3.11-rc1 since it fixed a bug in
device tree (incorrect polarity specification), and hence was suitable to
be included early in the rc series. I evidently did not test the patch at
all, or correctly, in the context of v3.11, and hence did not notice the
issue that I have explained above:-(
Fix this by making the USB VBUS regulators always enabled. This way, if
the regulator owns the GPIO, it will always be turned on, even if there
is no USB driver code to request the regulator be turned on. Even
ignoring this bug, this is a reasonable way to configure the HW anyway.
If this patch is applied to v3.11, it will cause a couple pretty trivial
conflicts in tegra20-{trimslice,seaboard}.dts when creating v3.12, since
the context right above the added lines changed in patches destined for
v3.12.

Currently set_secondary_cpus_clock assume the CPU logical ordering
and the MPDIR in DT are same, which is incorrect.
Since the CPU device nodes can be retrieved in the logical ordering
using the DT helper, we can remove the devices tree parsing.

Currently the topology code computes cpu capacity and stores it in
the list along with hwid(which is MPIDR) as it parses the CPU nodes
in the device tree. This is required as it needs to be mapped to the
logical CPU later.
Since the CPU device nodes can be retrieved in the logical ordering
using DT/OF helpers, its possible to store cpu_capacity also in logical
ordering and avoid storing hwid for each entry.
This patch removes hwid by making use of of_get_cpu_node.

OF/DT core library now provides architecture specific hook to match the
logical cpu index with the corresponding physical identifier. Most of the
cpu DT node parsing and initialisation is contained in devtree.c. So it's
better to define ARM specific arch_match_cpu_phys_id there.
This mainly helps to avoid replication of the code doing CPU node parsing
and physical(MPIDR) to logical mapping.
