There are lots of warnings produced by this driver. It is not
as much as atomisp, but it is still a lot.
So, use the same solution to hide most of them.
Those need to be fixed before promoting it out of staging,
so add it at the TODO list.

The runtime PM of this device is enabled after v4l2_ctrl_handler_setup(),
and this makes this device's runtime PM usage count a negative value.
The ov7740_set_ctrl() tries to do something only if the device's runtime
PM usage counter is nonzero.
ov7740_set_ctrl()
{
if (!pm_runtime_get_if_in_use(&client->dev))
return 0;
<do something>;
pm_runtime_put(&client->dev);
return ret;
}
However, the ov7740_set_ctrl() is called by v4l2_ctrl_handler_setup()
while the runtime PM of this device is not yet enabled. In this case,
the pm_runtime_get_if_in_use() returns -EINVAL (!= 0).
Therefore we can't bail out of this function and the usage count is
decreased by pm_runtime_put() without increment.
This fixes this problem by enabling the runtime PM of this device before
v4l2_ctrl_handler_setup() so that the ov7740_set_ctrl() is always called
when the runtime PM is enabled.

The CSI controller can take raw data from the data bus and output it
directly to capture buffers. This can be used to support the JPEG media
bus format.
While the controller can report minimum and maximum bytes per line, it
has no way to report how many lines were captured in the last frame.
Thus, even when the on-bus data is framed correctly, we have no way to
accertain the actual amount of data captured, unless we scan the buffer
for JPEG EOI markers, or sequential zeros. For now we leave bytesused
alone, and leave it up to userspace applications to parse the data.

max_register is currently set to 0x1000. This is beyond the mapped
address range of the hardware, so attempts to dump the regmap from
debugfs would trigger a kernel exception.
Furthermore, the useful registers only occupy a small section at the
beginning of the full range. Change the value to 0x9c, the last known
register on the V3s and H3.
On the A31, the register range is extended to support additional
capture channels. Since this is not yet supported, ignore it for now.

but the default CSI_SCLK rate cannot work properly to drive the

The tested mod cock rate is 300 MHz and BSP vfe media driver is also
using the same rate. Unfortunately there is no valid information about
clock rate in manual or any other sources except the BSP driver. so more
faith on BSP code, because same has tested in mainline.

Each control class reference is also moved up one level into the

Finally I rearranged the order so that all camera-related control
classes are grouped together, ditto for codec/jpeg and fm-rx/tx.
The ext-ctrls-codec.rst is still pretty big and it is a candidate
