What happens is that cmd_cnt tracks the amount of firmware data packets

Switch to use the firmware count, as the message is all about reporting

"link-frequencies" props
Some standard v4l2 sensor drivers from drivers/media/i2c expect a
"clock-frequency" property on the device indicating the frequency
of the extclk for the sensor. Example of such drivers are the
ov2680 and ov5693 drivers.
The standard ov5693 sensor also expects a "link-frequencies" property.
Add support for setting both properties.
Note the "clock-frequency" prop is added before the "rotation" prop while
the "link-frequencies" are added at the end to match the ipu3 cio2-bridge

This also removes the double writing of OV2680_REG_SOFT_RESET in

with padding
Now that atomisp_get_padding() takes minimum padding requirements
on BYT/ISP2400 into account, it is possible for a resolution which
fits in the active area of the sensor to not fit in the native area
once padding is added.
For example on the ov2680 which has a native resolution of 1616x1216
the max active resolution of 1600x1200 leaves 16x16 for padding which
meets the worst-case minimum padding requirement of 14x14 on BYT.
But after binning we are left with an native area of 808x608 and
an active area of 800x600. This leaves 8x8 for padding which is not
enough. So on BYT 800x600 is not a valid resolution (it could be
made by lots of cropping without binning but then the remaining
field of view is no good).
Modify atomisp_enum_framesizes_crop() to check the resolution +
padding fits in the native rectangle, removing 800x600 from
the list of valid modes on BYT.

The main binary for the pipeline on BYT/ISP2400 has its
ia_css_binary_info.pipeline.left_cropping and .top_cropping fields
set to 12. So a minimum padding of 12 is required.
And for certain bayer-orders additional width / height padding is
necessary so that the ISP crop rectangle for the raw sensor data
can be used to change the bayer-order to the fixed bayer-order
supported by the debayer block.
Without the minmum required padding ia_css_ifmtr_configure() will fail
inside ifmtr_input_start_line() and/or ifmtr_start_column() because
it cannot set the ISP crop rectangle for the raw sensor data.
Fix this by making atomisp_get_padding() take the minimum padding
requirements into account on BYT/ISP2400 (CHT/ISP2401 does not seem to
need this).

The ACPI code takes care of enabling/disabling the PMC clk(s) for
the sensors as necessary based on the runtime-pm state of the sensor.
But the GMIN code this replaces also set the clk-rate of the PMC clk
to 19.2 MHz. At least on BYT devices the PMC clks may come up running
at 25 MHz instead of the expected 19.2 MHz.
Ensure the sensor clk also runs at the expected 19.2 MHz for sensors

crop support
Some sensor drivers with crop support (e.g. the ov5693 driver) only
return the current crop rectangle + 1/2 (binning) of the current crop
rectangle when calling their enum_frame_sizes op.
This causes 2 issues:
1. Atomisp sets to the crop area to include the padding, where as
the enum_framesizes ioctl should return values without padding.
2. With cropping a lot more standard resolutions are possible then
just these 2 and many apps limit the list given to the end user
to the list returned by enum_framesizes.
Add an alternative enum_framesizes function for sensors which support
cropping to fix both issues.

Make atomisp_init_sensor() check if the sensor supports binning.
This is a preparation patch for using the selection / crop support
to determine the padding values to use with a specific sensor.

A sensor driver's enum_frame_size pad-op may return -EINVAL when
v4l2_subdev_frame_size_enum.code is not set to a supported
MEDIA_BUS_FMT_* code.
Make atomisp_init_sensor() get the sensor's MEDIA_BUS_FMT_* code and
pass this when calling the enum_frame_size pad-op.

Sensor drivers which implement set_selection V4L2_SEL_TGT_CROP expect
v4l2_subdev_state.pads[pad].try_crop to have valid contents when calling
set_fmt with which == V4L2_SUBDEV_FORMAT_TRY since the crop-rectangle
may influence the available image size.
Just passing an uninitalized struct v4l2_subdev_pad_config from
the stack to set_fmt with which == V4L2_SUBDEV_FORMAT_TRY will result
in wrong results with such drivers.
Store a per sensor v4l2_subdev_pad_config and add a new
atomisp_init_sensor_crop() function to initialize this before
registering /dev/* nodes with userspace.
Sensor drivers which implement the selection API will allow
the atomisp to properly deal with the extra padding the ISP wants
on a per sensor basis instead of hardcoding this.
atomisp_init_sensor_crop() stores the native and active rects
of the sensor in preparation for using these for this.
