Merge tag 'pinctrl-v3.12-1' of 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.

99f2b13037 ARM: PCI: versatile: Fix SMAP register offsets
The SMAP register offsets in the versatile PCI controller code were
all off by four.  (This didn't have any observable bad effects
because on this board PHYS_OFFSET is zero, and (a) writing zero to
the flags register at offset 0x10 has no effect and (b) the reset
value of the SMAP register is zero anyway, so failing to write SMAP2
didn't matter.)

829f9fedee ARM: PCI: versatile: Fix PCI I/O
The versatile PCI controller code was confused between the
PCI I/O window (at 0x43000000) and the first PCI memory
window (at 0x44000000). Pass the correct base address to
pci_remap_io() so that PCI I/O accesses work.

Since the first PCI memory window isn't used at all (it's
an odd size), rename the associated variables and labels
so that it's clear that it isn't related to the I/O window.

This has been tested and confirmed to fix PCI I/O accesses
both on physical PB926+PCI backplane hardware and on QEMU.

f9b71fef12 ARM: PCI: versatile: Fix map_irq function to match hardware
The PCI controller code for the Versatile board has never had the
correct IRQ mapping for hardware.  For many years it had an odd
mapping ("all interrupts are int 27") which aligned with the
equivalent bug in QEMU.  However as of commit 1bc39ac5da
the mapping changed and no longer matched either hardware or QEMU,
with the result that any PCI card beyond the first in QEMU would
not have functioning interrupts; for example a boot with a SCSI
controller would time out as follows:

 ------------
 sym0: <895a> rev 0x0 at pci 0000:00:0d.0 irq 92
 sym0: SCSI BUS has been reset.
 scsi0 : sym-2.2.3
 [...]
 scsi 0:0:0:0: ABORT operation started
 scsi 0:0:0:0: ABORT operation timed-out.
 scsi 0:0:0:0: DEVICE RESET operation started
 scsi 0:0:0:0: DEVICE RESET operation timed-out.
 scsi 0:0:0:0: BUS RESET operation started
 scsi 0:0:0:0: BUS RESET operation timed-out.
 scsi 0:0:0:0: HOST RESET operation started
 sym0: SCSI BUS has been reset
 ------------

Fix the mapping so that it matches real hardware (checked against the
schematics for PB926 and backplane, and tested against the hardware).
This allows PCI cards using interrupts to work on hardware for the
first time; this change will also work with QEMU 1.5 or later, where
the equivalent bugs in the modelling of the hardware have been fixed.

Although QEMU will attempt to autodetect whether the kernel is
expecting the long-standing "everything is int 27" mapping or the one
hardware has, for certainty we force it into "definitely behave like
hardware mode"; this will avoid unexpected surprises later if we
implement sparse irqs. This is harmless on hardware.

Thanks to Paul Gortmaker for bisecting the problem and finding an initial
solution, to Russell King for providing the correct interrupt mapping,
and to Guenter Roeck for providing an initial version of this patch
and prodding me into relocating the hardware and retesting everything.

40031da445 ACPI and power management updates for 3.12-rc1
1) ACPI-based PCI hotplug (ACPIPHP) subsystem rework and introduction
     of Intel Thunderbolt support on systems that use ACPI for signalling
     Thunderbolt hotplug events.  This also should make ACPIPHP work in
     some cases in which it was known to have problems.  From
     Rafael J Wysocki, Mika Westerberg and Kirill A Shutemov.
 
  2) ACPI core code cleanups and dock station support cleanups from
     Jiang Liu and Rafael J Wysocki.
 
  3) Fixes for locking problems related to ACPI device hotplug from
     Rafael J Wysocki.
 
  4) ACPICA update to version 20130725 includig fixes, cleanups, support
     for more than 256 GPEs per GPE block and a change to make the ACPI
     PM Timer optional (we've seen systems without the PM Timer in the
     field already).  One of the fixes, related to the DeRefOf operator,
     is necessary to prevent some Windows 8 oriented AML from causing
     problems to happen.  From Bob Moore, Lv Zheng, and Jung-uk Kim.
 
  5) Removal of the old and long deprecated /proc/acpi/event interface
     and related driver changes from Thomas Renninger.
 
  6) ACPI and Xen changes to make the reduced hardware sleep work with
     the latter from Ben Guthro.
 
  7) ACPI video driver cleanups and a blacklist of systems that should
     not tell the BIOS that they are compatible with Windows 8 (or ACPI
     backlight and possibly other things will not work on them).  From
     Felipe Contreras.
 
  8) Assorted ACPI fixes and cleanups from Aaron Lu, Hanjun Guo,
     Kuppuswamy Sathyanarayanan, Lan Tianyu, Sachin Kamat, Tang Chen,
     Toshi Kani, and Wei Yongjun.
 
  9) cpufreq ondemand governor target frequency selection change to
     reduce oscillations between min and max frequencies (essentially,
     it causes the governor to choose target frequencies proportional
     to load) from Stratos Karafotis.
 
 10) cpufreq fixes allowing sysfs attributes file permissions to be
     preserved over suspend/resume cycles Srivatsa S Bhat.
 
 11) Removal of Device Tree parsing for CPU device nodes from multiple
     cpufreq drivers that required some changes related to
     of_get_cpu_node() to be made in a few architectures and in the
     driver core.  From Sudeep KarkadaNagesha.
 
 12) cpufreq core fixes and cleanups related to mutual exclusion and
     driver module references from Viresh Kumar, Lukasz Majewski and
     Rafael J Wysocki.
 
 13) Assorted cpufreq fixes and cleanups from Amit Daniel Kachhap,
     Bartlomiej Zolnierkiewicz, Hanjun Guo, Jingoo Han, Joseph Lo,
     Julia Lawall, Li Zhong, Mark Brown, Sascha Hauer, Stephen Boyd,
     Stratos Karafotis, and Viresh Kumar.
 
 14) Fixes to prevent race conditions in coupled cpuidle from happening
     from Colin Cross.
 
 15) cpuidle core fixes and cleanups from Daniel Lezcano and
     Tuukka Tikkanen.
 
 16) Assorted cpuidle fixes and cleanups from Daniel Lezcano,
     Geert Uytterhoeven, Jingoo Han, Julia Lawall, Linus Walleij,
     and Sahara.
 
 17) System sleep tracing changes from Todd E Brandt and Shuah Khan.
 
 18) PNP subsystem conversion to using struct dev_pm_ops for power
     management from Shuah Khan.

9fc2105aea ARM: 7830/1: delay: don't bother reporting bogomips in /proc/cpuinfo
Now that we support a timer-backed delay loop, I'm quickly getting sick
and tired of people complaining that their beloved bogomips value has
decreased. You know who you are!

This patch removes the bogomips line from /proc/cpuinfo, based on the
reasoning that any program parsing this is already broken and, as such,
won't be further broken if the field is removed.

It appears that gcc may put some code in ".text.unlikely" or

7658ea2fb5 ARM: shmobile: r8a7779: Update early timer initialisation order
a894fcc2d0 ("ARM: smp_twd: Divorce smp_twd
from local timer API") altered twd_local_timer_common_register() so that it
may make use of late_timer_init.

This is problematic on marzen with Magnus's recent patch "ARM: shmobile:
marzen: Switch to DT_MACHINE_START" which switches marzen around to enable
USE_OF and thus shmobile_timer_init(), which is registered as
late_time_init by shmobile_earlytimer_init() stops being a no-op.

As a work-around I have updated r8a7779_earlytimer_init() so that
shmobile_earlytimer_init() is called after r8a7779_register_twd().
Or in other words, the shmobile_earlytimer_init() setting of
late_time_init overwrites that of twd_local_timer_common_register().

620f5e1cbf dts: Rename DW APB timer compatible strings
"dw-apb-timer-osc" and "dw-apb-timer-sp" are the same implementation of the
DW APB timer, just fed by different clocks. Thus, deprecate both
"dw-apb-timer-osc" and "dw-apb-timer-sp" in lieu of "dw-apb-timer".

9b9ae16a97 ASoC: Samsung: Do not queue cyclic buffers multiple times
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.

35f5df6fd8 OMAPDSS: fix DPI and SDI device ids
The DPI and SDI platform devices are currently created with the ID of
-1. The ID doesn't currently affect anything.

However, we have added regulator supply entries for "omapdss_dpi.0" and
"omapdss_sdi.0" to the board files, although these supply entries are
not yet used. As the ID used for the devices is -1, these regulator
supply entries will not work.

To fix the issue, assign ID of 0 to the devices. In the future there may
be more than one DPI or SDI output, so it makes sense to have a proper
ID for them.

9ee2ee0f05 ARM: vexpress: tc2: disable GIC CPU IF in tc2_pm_suspend
To prevent cores from exiting wfi when they are about to be shut down
the GIC CPU IF must be disabled so that the GIC CPU IF IRQ output line
is not asserted to the cores. wfi completion must be prevented since,
in absence of coordinating HW logic, if the power controller receives
a standbywfi signal but in the meantime the processor restarts executing
owing to a pending IRQ, the core might be reset when running in a
non-quiescent state (eg with pending load/store transactions)

Raw GIC distributor IRQ signals are routed to the power controller, that
is capable of taking core out of reset on pending IRQs even if their GIC
CPU IF is disabled, thus keeping the normal wfi behaviour.

GIC CPU IF is restored upon CPU wake-up by the respective MCPM API
consumers (ie CPU idle driver and suspend to RAM thread).

Note that the LCD add-on boards for lcd43 and lcd35 use the same GPIOs
for the panels. This means that both panel devices cannot be probed at
the same time.

DT will handle this correctly, i.e. the DT data will contain the panel
device only for the add-on board that is attached. However, for the
board file we need a hackish solution: We parse the kernel boot command
line, and see whether lcd43 or lcd35 is set as a default display, and
add the given one. Or, if neither is given, default to lcd43.

20d31345bd ARM: OMAP: 4430SDP: remove picodlp device data
4430SDP board has an option for a PicoDLP mini-projector. PicoDLP cannot
be used at the same time as the second LCD, and there are GPIOs that
need to be set/unset when changing the used display.

Managing that kind of board specific setup is not simple without board
file callbacks. As only some 4430SDP boards actually have the PicoDLP
installed, and 4430SDP boards are not that common in the first place,
let's remove PicoDLP data from the board file.

bfaddb7d13 msm_serial: Switch clock consumer strings and simplify code
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).

2ae847a1b1 usb: musb: am335x: add second port to beagle bone
So I assumed that Beagle bone has only one USB port in host mode because
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.

781f179830 usb: musb: am335x-evm: Do not remove the session bit HOST-only mode
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.

- remove the child node for USB. This is driver specific on won't be

- use the "mentor" prefix instead of "mg".
- use "dr_mode" istead of "mg,port-mode" for the port mode. The former
