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-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.

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.

c031a7d419 usb: usb: dsps: update code according to the binding document
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.

3b6394b4fa usb: musb: dsps fix the typo in reg-names of the dma node
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.

1e9fec0e40 ARM: EXYNOS: Skip C1 cpuidle state for exynos5440
This patch skips the deep C1(AFTR -Arm off top running) state for
exynos5440 SoC as this soc does not support this state. The cpu's
only allows the basic C0 state.
The C1 state is filtered by re-initialising the driver state_count
value to 1.
