way to reset the board to a working state is to reboot.

Included is checks of the TC_REQ and TC_REQ_SET registers during states
of board initialization, reset, DMA start, and DMA stop. If both registers
are set, this indicates a stall in the RiSC engine, at which point the
bridge error is cleared.
A small delay is introduced in stop_dma as well, to allow transfers in
progress to finish.
After application all models work on Ryzen, occasionally yielding:

C libraries with 64-bit time_t use an incompatible format for
struct omap3isp_stat_data. This changes the kernel code to
support either version, by moving over the normal handling
to the 64-bit variant, and adding compatiblity code to handle
the old binary format with the existing ioctl command code.
Fortunately, the command code includes the size of the structure,
so the difference gets handled automatically. In the process of
eliminating the references to 'struct timeval' from the kernel,
I also change the way the timestamp is generated internally,
basically by open-coding the v4l2_get_timestamp() call.

capture 10-bit and 12-bit grayscale formats, expanded to 16-bit

This patch adds support for V4L2_PIX_FMT_Y16 captured from sensors

media: renesas-ceu: Set mbus_fmt on subdev operations
The renesas-ceu driver intializes the desired mbus_format at 'complete'
time, inspecting the supported subdevice ones, and tuning some
parameters to produce the requested memory format from what the sensor
can produce. Although, the initially selected mbus_format was not
provided to the subdevice during set_fmt and try_fmt operations,
providing instead a '0' mbus format code.
As long as the sensor defaults to a compatible mbus_format when an
invalid code as '0' is provided, capture operations work correctly. If
the subdevice defaults to an unsupported format (eg. some RGB
permutations) capture does not work properly due to a mismatch on the
expected and received image format on the wire.
Fix that by re-using the initially selected mbus_format code during
set_fmt and try_fmt subdevice operation calls.
Tested by printing out the format selection procedure with ov7670
sensor.

This reverts commit
fc7f8fd42c2b934ac348995e0c530c917fc277d5.
Whilst the rationale for the above commit was in general correct, i.e.
that users *consuming* the DMA addresses should rely on sglen rather
than num_pages, it has always been the case that the DMA API itself
still requires that dma_{sync,unmap}_sg() are called with the original
number of entries as passed to dma_map_sg(), not the number of mapped
entries it returned. Thus the particular changes made in that patch
were erroneous.
At worst this might lead to data loss at the tail end of mapped buffers
on non-coherent hardware, while at best it's an example of incorrect
DMA API usage which has proven to mislead readers.

Since the commit "
8003c9ae204e: add APIC Timer periodic/oneshot mode VMX
preemption timer support", a Windows 10 guest has some erratic timer
spikes.
Here the results on a 150000 times 1ms timer without any load:
Before
8003c9ae204e | After
8003c9ae204e
Max 1834us | 86000us
Mean 1100us | 1021us

Here the results on a 150000 times 1ms timer with a cpu-z stress test:

Deviation 140us | 11095us
The root cause of the problem is starting hrtimer with an expiry time
already in the past can take more than 20 milliseconds to trigger the
timer function. It can be solved by forward such past timers
immediately, rather than submitting them to hrtimer_start().
In case the timer is periodic, update the target expiration and call
hrtimer_start with it.
v2: Check if the tsc deadline is already expired. Thank you Mika.
v3: Execute the past timers immediately rather than submitting them to
hrtimer_start().
v4: Rearm the periodic timer with advance_periodic_target_expiration() a
simpler version of set_target_expiration(). Thank you Paolo.

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.

earth-pt1 was a monolithic module and included demod/tuner drivers.
This patch removes those FE parts and attach demod/tuner i2c drivers.

media: tuners: add new i2c driver for Sharp qm1d1b0004 ISDB-S tuner
The tuner is used in Earthsoft PT1/PT2 DVB boards,
and the driver was extraced from (the former) va1j5jf8007s.c of PT1.
it might contain PT1 specific configs.
