ARM: PMU: fix runtime PM enable
Commit 7be2958 (ARM: PMU: Add runtime PM Support) updated the ARM PMU code to
use runtime PM which was prototyped and validated on the OMAP devices. In this
commit, there is no call pm_runtime_enable() and for OMAP devices
pm_runtime_enable() is currently being called from the OMAP PMU code when the
PMU device is created. However, there are two problems with this:
1. For any other ARM device wishing to use runtime PM for PMU they will need
to call pm_runtime_enable() for runtime PM to work.
2. When booting with device-tree and using device-tree to create the PMU
device, pm_runtime_enable() needs to be called from within the ARM PERF
driver as we are no longer calling any device specific code to create the
device. Hence, PMU does not work on OMAP devices that use the runtime PM
callbacks when using device-tree to create the PMU device.
Therefore, call pm_runtime_enable() directly from the ARM PMU driver when
registering the device. For platforms that do not use runtime PM,
pm_runtime_enable() does nothing and for platforms that do use runtime PM but
may not require it specifically for PMU, this will just add a little overhead
when initialising and uninitialising the PMU device.
Tested with PERF on OMAP2420, OMAP3430 and OMAP4460.

SERIAL: omap: fix hardware assisted flow control
When the UART device has hardware flow control enabled, it ignores the
MCR RTS bit in the MCR register, and keeps RTS asserted as long as we
continue to read characters from the UART receiver FIFO. This means
that when the TTY buffers become full, the UART doesn't tell the remote
end to stop sending, which causes the TTY layer to start dropping
characters.
A similar problem exists with software flow control. We need the FIFO
register to fill when software flow control is enabled to provoke the
UART to send the XOFF character.
Fix this by implementing the throttle/unthrottle callbacks, and use
these to disable receiver interrupts. This in turn means that the UART
FIFO will fill, which will then cause the UART's hardware to deassert
the RTS signal and/or send the XOFF character, stopping the remote end.

Fix this by ensuring that we always have ECB set whenever the TCRTLR bit

Moreover, we start out by reading the EFR and MCR registers, which may
have indeterminent bit settings for the ECB and TCRTLR bits. Ensure

clk_prepare()/clk_unprepare() calls cannot be called

just the tip of an iceberg as the function pair is not

This change makes the SMP_TWD clock .setup()/.stop() pair reentrant
by splitting the .setup() function in three parts:
- One COMMON part that is executed the first time the first CPU
in the TWD cluster is initialized. This will fetch the TWD
clk for the cluster and prepare+enable it. If no clk is
available it will calibrate the rate instead.
- One part that is executed the FIRST TIME a certain CPU is
brought on-line. This initializes and sets up the clock event
for a certain CPU.
- One part that is executed on every subsequent .setup() call.
This will re-initialize the clock event. This is augmented
to call the clk_enable()/clk_disable() pair properly.

Merge branch 'i2c-embedded/for-current' of git://git.pengutronix.de/git/wsa/linux
Pull i2c embedded fixes from Wolfram Sang:
"Two patches are usual stuff.
The bigger patch is needed to correct a wrong decision made in this
merge window. We hoped to get the PIOQUEUE mode in the mxs driver
working with DMA, but it turned out to be too broken (leading to data
loss), so we now think it is best to remove it entirely and work only
with DMA now. The patch should be in 3.7. IMO, so users never get
the chance to use both modes in parallel."

it's slightly bigger than I'd probably like, but nothing looked
dangerous enough to hold off on."

f7b2927 introduced tx checksum offload support for smsc95xx,
and enabled it by default. This feature doesn't take
endianness into account, so causes most tx to fail on
those platforms.
This patch fixes the problem fully by adding the missing
conversion.
An alternate workaround is to disable TX checksum offload
on those platforms. The cpu impact of this feature is very low.

rtnetlink: Use nlmsg type RTM_NEWNEIGH from dflt fdb dump
Change the dflt fdb dump handler to use RTM_NEWNEIGH to
be compatible with bridge dump routines.
The dump reply from the network driver handlers should
match the reply from bridge handler. The fact they were
not in the ixgbe case was effectively a bug. This patch
resolves it.
Applications that were not checking the nlmsg type will
continue to work. And now applications that do check
the type will work as expected.

ptp: update adjfreq callback description
This patch updates the adjfreq callback description to include a note that the
delta in ppb is always relative to the base frequency, and not to the current

drivers/net: use tasklet_kill in device remove/close process
Some driver uses tasklet_disable in device remove/close process,
tasklet_disable will inc tasklet->count and return. If the tasklet
is not handled yet because some softirq pressure, the tasklet will
placed on the tasklet_vec, never have a chance to excute. This might
lead to ksoftirqd heavy loaded, wakeup with pending_softirq, but
tasklet is disabled. tasklet_kill should be used in this case.
