The code is running arithmetics with the enum, which when not done with
care makes the compiler a bit nervous.
Because those enums are only used as defines (no argument or variable
from that enumeration type), convert it into a define and move on.
It is required to build with llvm 9 without these warnings:

Constifying this structure moves some data to a read-only section, so

In order to do that, struct dvb_usb_device_description (in dvb-usb.h) also
needs to be updated.

The mask to select the test-pattern in register ADV748X_SDP_FRP is
incorrect, it's the lower 3 bits which controls the pattern. The
GENMASK() macro is used incorrectly and the generated mask is 0x0e
instead of 0x07.
The result is that not all test patterns are selectable, and that in
some cases the wrong test pattern is activated. Fix this by correcting
the GENMASK().

vivid at low resolution with ffmpeg.
This was caused by:
while (time_is_after_jiffies(cur_jiffies + wait_jiffies) &&
!kthread_should_stop())

If there are no other processes running that can be scheduled,
then this is basically a busy-loop.

When the analog binning mode is used for high framerate operation, the
pixel rate is effectively doubled. Account for this when setting up the
pixel clock rate, and applying the vblank and exposure controls.
The previous logic only used analog binning for RAW8, but normal binning
limits the framerate on RAW10 480p [1]. So with this patch we switch to
using special binning (with 2x pixel rate) wherever possible.

The sensor's internal ADC supports a minimum line length of 3448 pixels,
which may be too small to use with analog binning, where ADC operates on
two lines together. Switch to a higher minimum line length of 3560
pixels to fix the blocky artefacts seen with analog binning [1].
To keep the same default framerate as before for all the modes, lower
the default fll value to compensate for the increase in llp.

The HBLANK control was read-only, and always configured such that the
sensor line length register was 3448. This limited the maximum exposure
time that could be achieved to around 1.26 secs.
Make HBLANK read/write so that the line time can be extended, and
thereby allow longer exposures (and slower frame rates). Retain the
overall line length setting when changing modes rather than resetting it
to a default.

Commit ceddfd4493b3 ("media: i2c: imx219: Support four-lane operation")
added support for device tree to allow configuration of the sensor to
use 4 lanes with a link frequency of 363MHz, and amended the advertised
pixel rate to 280.8MPix/s.
However it didn't change any of the PLL settings, so actually it would
have been running overclocked in the MIPI block, and with the frame
rate and exposure calculations being wrong as the pixel rate was
unchanged.
The pixel rate and link frequency advertised were taken from the "Clock
Setting Example" section of the datasheet. However those are based on an
external clock of 12MHz, and are unachievable with a clock of 24MHz - it
seems PREPLLCLK_VT_DIV and PREPLLCK_OP_DIV can ONLY be set via the
automatic configuration documented in "9-1-2 EXCK_FREQ setting depend on
INCK frequency", not by writing the registers.
The closest we can get with a 24MHz clock is 281.6MPix/s and 364MHz.
Dropping all support for the 363MHz link frequency would cause problems
for existing users, so allow it, but log a warning that the requested
value is being changed to the supported one.

The link frequencies are equally valid in 2 or 4 lane modes, but
they change the hmax_min value for the mode as the MIPI block
has to have sufficient time to send the pixel data for each line.
Remove the association with number of lanes, and add hmax_min
configuration for both lane options.

The control of HMAX documented in the datasheet is consistent
with being in terms of a scaled INCK, being always 72MHz or
74.25MHz. It is NOT link frequency dependent, but the minimum
value for HMAX is dictated by the link frequency.
If PIXEL_RATE is defined as being 12 times the 72 or 74.25MHz,
and all values are scaled down again when writing HMAX, then
the numbers all work out regardless of INCK or link frequency.
Retain an hmax_min (set to the same value as the previous fixed
hmax register value) to set as the default value to avoid changing
the behaviour for existing users.

Call v4l2_async_register_subdev only whenever all initialization
are completed at the end of the probe function.

Within the stm32_csi_start function, pm_runtime_put should
be called upon error following pm_runtime_get_sync.
Rework the function error handling by putting a label in
order to have common error handling for all calls requiring
pm_runtime_put.
