====================
this is a pull-request for net-next/master. It consists of three
patches by Fabio Estevam and me, which convert the flexcan transceiver
switching to DT[1] and a patch by Sachin Kamat, which cleans up the
at91_can driver a bit.
[1] These patches touch arch/arm/mach-imx, so I collected Acked-bys
from Shawn Guo and Sascha Hauer.

This patch fixes the following warning introduced in e4fc408e0e99
("packet: nlmon: virtual netlink monitoring device for packet
sockets") reported by Dan Carpenter:
warning: "drivers/net/nlmon.c:31 nlmon_is_valid_mtu()
warn: always true condition '(new_mtu <= ((~0 >> 1))) =>
(s32min-s32max <= s32max)'"
Thus, we should simply remove the test against INT_MAX. Next to that
we also need to explicitly cast the sizeof() case as the comparison
is type promoted to unsigned long so negative values are then
valid instead of invalid. While at it, this also adds a comment about
Netlink and MTUs.

This patch prevents NULL pointer error cauesed by unregistering
unregistered exton notifier block. At the probing time of charger manager,
it tries to remove extcon notifier block when it fails to initialize them.
It has to be applied for only registered one. Otherwise, it'd make kernel
panic. To make it work right, it checks extcon_specific_cable_nb's
extcon_dev node. If extcon cable notifier block was registered
successfully, it has proper extcon_dev pointer if not so it has NULL
pointer.

This is patch 3/3 of a patch set that cleans up pstore_register failure paths.

This is patch 2/3 of a patch set that avoids what misleadingly appears
to be a error during boot:
ERST: Could not register with persistent store
This message is displayed if the system has a valid ACPI ERST table and the
pstore.backend kernel parameter has been used to disable use of ERST by
pstore. But this same message is used for errors that preclude registration.
In erst_init don't complain if the setting of kernel parameter pstore.backend
precludes use of ACPI ERST for pstore. Routine pstore_register will inform
about the facility that does register.
Also, don't leave a dangling pointer to deallocated mem for the pstore
buffer when registration fails.

Link start-up requires long time with multiphase handshakes
between UFS host and device. This affects driver's probe time.
This patch let link start-up run asynchronously. Link start-up
will be executed at the end of prove separately.
Along with this change, the following is worked.
Defined completion time of uic command to avoid a permanent wait.
Added mutex to guarantee of uic command at a time.
Adapted some sequence of controller initialization after link statup

This patch changes the firmware file names of the FIMC-IS subsystem.
It is needed since there are different firmwares used across various
SoC series, e.g. Exynos4 and Exynos5.
Also the sensor specific "setfile" name is changed, to account for
it depends on an image sensor and is also specific to the FIMC-IS
and the SoC.
This is a change for a driver merged in 3.10.

Add compatible property for the Exynos5250 and enable the frame start
and frame end interrupts. These interrupts are needed for the Exynos5
FIMC-IS firmware. The driver enables those interrupt only where available,
depending on the 'compatible' property. This can be optimized further,
by exposing some API at the subdev driver, so the host driver can enable
extra interrupts only for the image processing chains involving FIMC-IS.

This patch adds support for the Exynos5250 SoC variant of the FIMC-LITE
IP. A 'compatible' string is added for Exynos5250 compatible devices
and the capture DMA handling is reworked to use the FLITE_REG_CIFCNTSEQ
register, masking output DMA buffer address slots. The frame interrupt
is enabled so there are now 2 interrupts per frame. This likely can be
optimized in future by using any status registers that allow to figure
out what the last and the currently written frame buffer is. It would
also be more reliable in cases where there are high interrupt service
latencies.
