media: intel-ipu3: cio2: Handle IRQs until INT_STS is cleared
Interrupt behavior shows that some time the frame end and frame start of
next frame is unstable and can range from several to hundreds of
micro-sec. In the case of ~10us, isr may not clear next sof interrupt
status in single handling, which prevents new interrupts from coming.
Fix this by handling all pending IRQs before exiting isr, so any abnormal
behavior results from very short interrupt status changes is protected.

media: rcar-vin: enable field toggle after a set number of lines for Gen3
The VIN Gen3 hardware don't have Line Post-Clip capabilities as VIN Gen2
hardware have. To protect against writing outside the capture window
enable field toggle after a set number of lines have been captured.
Capturing outside the allocated capture buffer where observed on R-Car
Gen3 Salvator-XS H3 from the CVBS input if the standard is
misconfigured. That is if a PAL source is connected to the system but
the adv748x standard is set to NTSC. In this case the format reported by
the adv748x is 720x480 and that is what is used for the media pipeline.
The PAL source generates frames in the format of 720x576 and the field
is not toggled until the VSYNC is detected and at that time data have
already been written outside the allocated capture buffer.
With this change the capture in the situation described above results in
garbage frames but that is far better then writing outside the capture
buffer.

The -Warray-bounds warning in gcc-8 triggers for a newly added file:
drivers/media/spi/cxd2880-spi.c: In function 'cxd2880_write_reg':
drivers/media/spi/cxd2880-spi.c:111:3: error: 'memcpy' forming offset [133, 258] is out of the bounds [0, 132] of object 'send_data' with type 'u8[132]' {aka 'unsigned char[132]'} [-Werror=array-bounds]
The problem appears to be that we have two range checks in this function,
first comparing against BURST_WRITE_MAX (128) and then comparing against
a literal '255'. The logic checking the buffer size looks at the second
one and decides that this might be the actual maximum data length.
This is understandable behavior from the compiler, but the code is actually
safe. Since the first check is already shorter, we can remove the loop
and only leave that. To be on the safe side in case BURST_WRITE_MAX might
be increased, I'm leaving the check against U8_MAX.

media: ddbridge: initial support for MCI-based MaxSX8 cards
This adds initial support for the new MCI-based (micro-code interface)
DD cards, with the first one being the MaxSX8 eight-tuner DVB-S/S2/S2X
PCIe card. The MCI is basically a generalized interface implemented in
the card's FPGA firmware and usable for all kind of cards, without the
need to implement any demod/tuner drivers as this interface "hides" any
I2C interface to the actual ICs, in other words any required driver is
implemented in the card firmware.
At this stage, the MCI interface is quite rudimentary with things like
signal statistics reporting missing, but is already working to serve
DVB streams to DVB applications. Missing functionality will be enabled
over time.
This implements only the ddbridge-mci sub-object and hooks it up to the
Makefile so the object gets build. The upcoming commits hook this module
into all other ddbridge parts where required, including device IDs etc.
