The newly added x550em_a support causes a link failure on ARM because of

There are multiple variants of the ixgbe_acquire_swfw_sync_*() function,

Several areas of ixgbe were written before widespread usage of the
BIT(n) macro. With the impending release of GCC 6 and its associated new
warnings, some usages such as (1 << 31) have been noted within the ixgbe
driver source. Fix these wholesale and prevent future issues by simply
using BIT macro instead of hand coded bit shifts.
Also fix a few shifts that are shifting values into place by using the
'u' prefix to indicate unsigned. It doesn't strictly matter in these
cases because we're not shifting by too large a value, but these are all
unsigned values and should be indicated as such.

The tcrypt testing module on Exynos5422-based Odroid XU3/4 board failed on
testing 8 kB size blocks:

test 3 (128 bit key, 1024 byte blocks): 21685 operations in 1 seconds (22205440 bytes)
test 4 (128 bit key, 8192 byte blocks):
This was caused by a race issue of missed BRDMA_DONE ("Block cipher
Receiving DMA") interrupt. Device starts processing the data in DMA mode
immediately after setting length of DMA block: receiving (FCBRDMAL) or
transmitting (FCBTDMAL). The driver sets these lengths from interrupt
handler through s5p_set_dma_indata() function (or xxx_setdata()).
However the interrupt handler was first dealing with receive buffer
(dma-unmap old, dma-map new, set receive block length which starts the
operation), then with transmit buffer and finally was clearing pending
interrupts (FCINTPEND). Because of the time window between setting
receive buffer length and clearing pending interrupts, the operation on
receive buffer could end already and driver would miss new interrupt.
User manual for Exynos5422 confirms in example code that setting DMA
block lengths should be the last operation.
The tcrypt hang could be also observed in following blocked-task dmesg:

The adv7180 attempts to autodetect the standard. Unfortunately this
is seriously broken.
This patch removes the autodetect completely. Only the querystd op
will detect the standard. Since the design of the adv7180 requires
that you switch to a special autodetect mode you cannot call querystd
when you are streaming.
So the s_stream op has been added so we know whether we are streaming
or not, and if we are, then querystd returns EBUSY.
After testing this with a signal generator is became obvious that
a sleep is needed between changing the standard to autodetect and
reading the status. So the autodetect can never have worked well.
The s_std call now just sets the new standard without any querying.
If the driver supports the interrupt, then when it detects a standard
change it will signal that by sending the V4L2_EVENT_SOURCE_CHANGE
event.
With these changes this driver now behaves like all other video
receivers.
