The DesignWare I2C controller has high count (HCNT) and low count (LCNT)
registers for each of the I2C speed modes (standard and fast). These
registers are programmed based on the input clock speed in the driver.
The current code calculates these values based on the input clock speed and
tries hard to meet the I2C bus timing requirements. This could result
non-optimal values with regarding to the bus speed. For example on Intel
BayTrail we get bus speed of 315.41kHz which is ~20% slower than we would
expect (400kHz) in fast mode (even though the timing requirements are met).
This patch makes it possible for the platform code to pass more optimal
HCNT/LCNT values to the core driver if they are known beforehand. If these
are not set we use the calculated and more conservative values.

make the MPC I2C driver get, prepare and enable the gated clock item for
register access during probe; disable and unprepare the clock upon
remove(), put is done by the devm approach; hold a reference to the
clock over the period of use
clock lookup is non-fatal in this implementation as not all platforms
may provide clock specs in their device tree, but failure to enable a
clock when specified is considered fatal

Use new display drivers for AM3517EVM board.

Note: the management of LCD GPIOs is unclear. They were originally muxed
as inputs, and LCD_PANEL_PWR was labelled as "dvi enable".

Use the new display drivers for OMAP3 Overo board.

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.

The net_device might be not set on the skb when we try refcounting.
This leads to a null pointer dereference in xdst_queue_output().
It turned out that the refcount to the net_device is not needed
after all. The dst_entry has a refcount to the net_device before
we queue the skb, so it can't go away. Therefore we can remove the
refcount on queueing to fix the null pointer dereference.

The recent commit to delay the release of kobject triggered NULL
dereferences of opti9xx drivers. The cause is that all
snd-opti92x-ad1848, snd-opti92x-cs4231 and snd-opti93x drivers
register the PnP card driver with the very same name, and also
snd-opti92x-ad1848 and -cs4231 drivers register the ISA driver with
the same name, too. When these drivers are built in, quick
"register-release-and-re-register" actions occur, and this results in
Oops because of the same name is assigned to the kobject.
The fix is simply to assign individual names. As a bonus, by using
KBUILD_MODNAME, the patch reduces more lines than it adds.
The fix is based on the suggestion by Russell King.

This patch adds support for virtual IOMMU to the vmci module. We switch
to DMA consistent mappings for guest queuepair and doorbell pages that
are passed to the device. We still allocate each page individually,
since there's no guarantee that we'll get a contiguous block of physical
for an entire queuepair (especially since we allow up to 128 MiB!).
Also made the split between guest and host in the kernelIf struct much
clearer. Now it's obvious which fields are which.
