This patch adds a frontend driver for the Socionext/Panasonic
MN884434 and MN884433 ISDB-S/T demodulators.
The maximum and minimum frequency of MN88443x comes from
ISDB-S and ISDB-T so frequency range is the following:
- ISDB-S (BS/CS110 IF frequency, Local freq 10.678GHz)
- Min: BS-1: 1032MHz
- Max: ND24: 2070MHz
- ISDB-T
- Min: ch13: 470MHz

while the Hauppauge WinTV dualHD enables discarding NULL packets by
default.
However, some applications require NULL packets, e.g. to determine the
load in DOCSIS segments, so discarding NULL packets is undesired for
such applications.
This patch simply extends the bit mask when starting or stopping the
transport stream packet capture, so that the filter bits are cleared.

Look up of buffers in s5p_mfc_handle_frame_new, s5p_mfc_handle_frame_copy_time
functions is not working properly for DMA addresses above 2 GiB. As a result
flags and timestamp of returned buffers are not set correctly and it breaks
operation of GStreamer/OMX plugins which rely on the CAPTURE buffer queue
flags.
Due to improper return type of the get_dec_y_adr, get_dspl_y_adr callbacks
and sign bit extension these callbacks return incorrect address values,
e.g. 0xfffffffffefc0000 instead of 0x00000000fefc0000. Then the statement:
"if (vb2_dma_contig_plane_dma_addr(&dst_buf->b->vb2_buf, 0) == dec_y_addr)"
is always false, which breaks looking up capture queue buffers.
To ensure proper matching by address u32 type is used for the DMA
addresses. This should work on all related SoCs, since the MFC DMA
address width is not larger than 32-bit.
Changes done in this patch are minimal as there is a larger patch series

media: imx274: add cropping support via SELECTION API
Currently this driver does not support cropping. The supported modes
are the following, all capturing the entire area:
- 3840x2160, 1:1 binning (native sensor resolution)
- 1920x1080, 2:1 binning
- 1280x720, 3:1 binning
The VIDIOC_SUBDEV_S_FMT ioctl chooses among these 3 configurations the
one that matches the requested format.
Add cropping support via VIDIOC_SUBDEV_S_SELECTION: with target
V4L2_SEL_TGT_CROP to choose the captured area, with
V4L2_SEL_TGT_COMPOSE to choose the output resolution.
To maintain backward compatibility we also allow setting the compose
format via VIDIOC_SUBDEV_S_FMT. To obtain this, compose rect and
output format are computed in the common helper function
__imx274_change_compose(), which sets both to the same width/height
values.
Cropping also calls __imx274_change_compose() whenever cropping rect
size changes in order to reset the compose rect (and output format
size) for 1:1 binning.
Also rename enum imx274_mode to imx274_binning (and its values from
IMX274_MODE_BINNING_* to IMX274_BINNING_*). Without cropping, the two
naming are equivalent. With cropping, the resolution could be
different, e.g. using 2:1 binning mode to crop 1200x960 and output a
600x480 format. Using binning in the names avoids any
misunderstanding. For the same reason, replace the 'size' field in
struct imx274_frmfmt with 'bin_ratio'.

The dw9807 contains a voice coil lens driver as well as an EEPROM. This

already the case for the compatible string, for instance.

The ADV7180 and ADV7182 transmit whole fields, bottom field followed
by top (or vice-versa, depending on detected video standard). So
for chips that do not have support for explicitly setting the field
mode via I2P, set the field mode to V4L2_FIELD_ALTERNATE.
I2P converts fields into frames using an edge adaptive algorithm. The
frame rate is the same as the 'field rate': e.g. X fields per second
are now X frames per second.
