0000000000000000.
[ 16.344378] cxusb: i2c wr: len=64 is too big!
64 bytes is too short for firmware load on this device. So, increase it
to 80 bytes.

[media] xc4000: Fix get_frequency()
The programmed frequency on xc4000 is not the middle
frequency, but the initial frequency on the bandwidth range.
However, the DVB API works with the middle frequency.
This works fine on set_frontend, as the device calculates
the needed offset. However, at get_frequency(), the returned
value is the initial frequency. That's generally not a big
problem on most drivers, however, starting with changeset
6fe1099c7aec, the frequency drift is taken into account at
dib7000p driver.
This broke support for PCTV 340e, with uses dib7000p demod and
xc4000 tuner.

items.
Using the initialized context property, SEQ_END is only queued in
coda_release when needed.

[media] coda: add selection API support for h.264 decoder
The h.264 decoder produces capture frames that are a multiple of the macroblock
size (16 pixels). To inform userspace about invalid pixel data at the edges,
use the active and padded composing rectangles on the capture queue.
The cropping information is obtained from the h.264 sequence parameter set.

[media] coda: remove BUG() in get_q_data
This allows us to get rid of the now superfluous v4l2_m2m_get_vq check
in G_FMT. Also, we can use this to check the buffer type in G_SELECTION
later.

[media] coda: Add encoder/decoder support for CODA960
This patch adds support for the CODA960 VPU in Freescale i.MX6 SoCs.
It enables h.264 and MPEG4 encoding and decoding support. Besides the usual
register shifting, the CODA960 gains frame memory control and GDI registers
that are set up for linear mapping right now, needs ENC_PIC_SRC_INDEX to be
set beyond the number of internal buffers for some reason, and has subsampling
buffers that need to be set up. Also, the work buffer size is increased to
80 KiB.
The CODA960 firmware spins if there is not enough input data in the bitstream
buffer. To make it continue, buffers need to be copied into the bitstream as
soon as they are queued. As the bitstream fifo is written into from two places,
it must be protected with a mutex. For that, using a threaded interrupt handler
is necessary.
