Fraction bytes-per-pixel exist for some packed format. You will find
notably on Rockhip platform that 10bit data is stored fully packed,
meaning that there is 1.25 pixels per bytes. This can be represented
with the fraction 5/4 and can be used to scale the width into a
bytesperline.

"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
code from which this is derived.

ov2680_global_setting[]
Many of the values in ov2680_global_setting[] match the default/reset
register value for the ov2680 sensor (verified with both datasheet
and actual hw) so they are no-ops.
And there are also a couple of others which are later overwritten
by ctrls or by ov2680_set_mode().
Remove all the unnecessary entries and add annotations to
the remaining entries documenting what they change
(in so far as things are documented in the datasheet).
This also removes the double writing of OV2680_REG_SOFT_RESET in
ov2680_init_registers() (one direct write, one in ov2680_global_setting[])
instead add a short sleep after the first write to give the sensor
time to reset.

Stop using half pixelclock for binned modes this fixes:
1. The exposure being twice as high for binned mods (due to the half clk)
2. The framerate being 15 fps instead of 30 fps
The original code with fixed per mode register lists did use half pixel
clk, but this should be combined with using half for the VTS value too.
Using half VTS fixes the framerate issue, but this has the undesired
side-effect of change the exposure ctrl range (half the range, double
the amount of exposure per step).

No other V4L2 driver resets the selected input (front cam or back cam
selected in case of the atomisp).
Stop resetting selected input to 0 between /dev/video# opens.
This allows e.g. using v4l2-ctl -i to switch the input before starting
another app, which is useful since most apps don't support selecting
the input.
Note more in general the whole resetting of a bunch of internal
state from the open fop needs to be removed there to allow multiple
opens of /dev/video# for full v4l2 API compliance.

The fmt / size passed to atomisp_set_crop() includes padding,
so the binning check should be against 1/2 of the native rect.
of the sensor, rather then 1/2 of the active rect.
This fixes binning not being used when using e.g. 800x600 on
a 1600x1200 sensor leading to a very small field of view.

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
using v4l2-async probing by explicitly setting it to 19.2 MHz when
enumerating sensors in atomisp_csi2_bridge.c.

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.

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

Just passing an uninitalized struct v4l2_subdev_pad_config from

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.

There are a number of bugs in atomisp_try_fmt_cap() and atomisp_set_fmt():
1. atomisp_try_fmt_cap() uses atomisp_adjust_fmt() which adds the sensor
padding to the width passed to atomisp_adjust_fmt() to calculate
bytesperline. This is buggy for 2 reasons:
a) The width passed to atomisp_adjust_fmt() already contains
the sensor padding.
b) The fmt returned by atomisp_try_fmt_cap() is the fmt outputted by
the ISP and the sensor padding applies to the input side of the ISP
not the output side. The output side of the ISP has its own padding /
pitch requirements which have nothing to do with the sensor.
Both these issues are fixed in this refactor by switching to
ia_css_frame_pad_width() to calculate the padding.
2. atomisp_set_fmt() takes the passed in bytesperline value without
doing any validation on it and then passes this unchecked value to
the configure_output() callback.
If bytesperline converted to pixels is > 1920 ia_css_binary_find()
will fail to find a valid binary for the preview pipeline triggering
a dump_stack_lvl() call inside ia_css_binary_find() and causing
atomisp_set_fmt() to fail.
This is fixed by making atomisp_set_fmt() call atomisp_try_fmt()
first which we override the userspace specified bytesperline with
the correct value.
Besides this bug there is also a bunch of weirdness and a lot of
duplication in the code:
1. atomisp_try_fmt_cap() adds the sensor padding itself but then
it gets substracted again in atomisp_adjust_fmt() not doing
the addition + substraction in the same place makes the code hard
to follow (weirdness).
2. atomisp_set_fmt() starts with basically an atomisp_try_fmt() call,
except that the only atomisp_try_fmt() caller: atomisp_try_fmt_cap()
adds the sensor padding itself rather than letting atomisp_try_fmt()
do this (duplication).
3. Both atomisp_try_fmt_cap() and atomisp_set_fmt() contain code to
lookup the bridge-format matching the requested pixelformat and
both will fallback to YUV420 if this is not set (duplication).
4. Both atomisp_try_fmt_cap() and atomisp_set_fmt() contain code to
fill in the passed in v4l2_pix_format struct (duplication).
Cleanup all of this (and fix the bugs mentioned above) by:
1. Adding a new atomisp_fill_pix_format() helper which properly uses
ia_css_frame_pad_width() to calculate bytesperline.
2. Move all sensor padding handling to atomisp_try_fmt() and
make atomisp_try_fmt() fill the passed in v4l2_pix_format struct.
3. This reduces atomisp_try_fmt_cap() to just a small wrapper around
atomisp_try_fmt().
4. Replace the DIY try_fmt code at the beginning of atomisp_set_fmt()
with atomisp_try_fmt(), this will also override/fix the bytersperline
passed by userspace.
5. Replace the DIY v4l2_pix_format filling at the end of atomisp_set_fmt()
with atomisp_fill_pix_format().

Passing 'isp->asd->inputs[asd->input_curr].foo' as argument to
various function calls is rather long.
Add a local input helper variable for this, so that the function
calls will fit on one line.

atomisp_set_fmt*() use a local v4l2_subdev_fh declared on the stack,
specifically they use fh.state which is never initialized so when
passing fh.state to atomisp_subdev_set_ffmt() / to
atomisp_subdev_set_selection() these functions are passing random
stack contents as a pointer.
The reason this works is because when the which parameter is
V4L2_SUBDEV_FORMAT_ACTIVE the passed in state is not used.
Remove the bogus fh usage and just pass NULL as state.

As the 2 comments in the function already say both the sink and the source
pads only support setting the selection for 1 target:
/* Only crop target supported on sink pad. */
/* Only compose target is supported on source pads. */
Validate that the passed in target actually matches these expectations.

atomisp_set_fmt()
With the atomisp_subdev_set_selection(sink-pad, V4L2_SEL_TGT_CROP, rect)
calls dropped. The first and last compount code blocks of the 3 code blocks
in the if (...) {} else if (...) {} else {} code setting the source-pad
V4L2_SEL_TGT_COMPOSE selection are the same.
The both set V4L2_SEL_TGT_COMPOSE to a rectangle with the same dimensions
as f->fmt.pix.height.
Remove the else {} block at the end, drop the second if and prepend
the first if condition with "!second-if-condition ||" to remove
the code duplication.

atomisp_set_fmt()
atomisp_subdev_set_selection(sink-pad, V4L2_SEL_TGT_CROP, rect)
ignores the passed in rect, using the width and height from the last
atomisp_subdev_set_ffmt(ATOMISP_SUBDEV_PAD_SINK, ffmt) call instead.
The atomisp_subdev_set_ffmt() call done by atomisp_set_fmt_to_snr()
already propagates the sink ffmt changes to V4L2_SEL_TGT_CROP
(this is what allows atomisp_set_fmt() to get the isp_sink_crop in
the first place).
Remove the redundant atomisp_subdev_set_selection(sink-pad, ...)
calls.
Note the removed aspect ratio correction in the last else block is
is already done by atomisp_subdev_set_selection() itself when
setting V4L2_SEL_TGT_COMPOSE on the source-pad.

Remove a bunch of sensor related custom IOCTLs because:
1. They are custom IOCTLs and all custom IOCTLs should be removed
2. Userspace should directly talk to the sensor v4l2-subdev, rather
then relying on ioctl-s on the output /dev/video# node to pass
through ioctl-s to the senor
3. Some of these rely on the atomisp specific camera_mipi_info struct
which is going away as we are switching to using standard v4l2
sensor drivers
4. In the case of ATOMISP_IOC_S_EXPOSURE_WINDOW this was using the
v4l2-subdev set_selection API in an undocumented atomisp custom way

Implement selection support. Modelled after ov5693 selection support,
but allow setting sizes smaller than crop-size through set_fmt since
that was already allowed.

Having an init_cfg to initialize the passed in subdev-state is
important to make which == V4L2_SUBDEV_FORMAT_TRY ops work when
userspace is talking to a /dev/v4l2-subdev# node.
Copy the ov2680_init_cfg() from the standard drivers/media/i2c/ov2680.c
driver.
This is esp. relevant once support for cropping is added where
the v4l2_subdev_state.pads[pad].try_crop rectangle needs to be set
correctly for set_fmt which == V4L2_SUBDEV_FORMAT_TRY calls to work.

A lot of work has been done on the atomisp driver lately.
Rewrite the TODO file to drop all the already fixed items:
* Moved to videobuf2 + fixed mmap support
* Whole bunch of v4l2 API fixes making more apps work
* v4l2-async sensor probing support
* pm-runtime support (for some sensor drivers at least)
* buffer MM code was cleaned up / replaced when moving the videobuf2
And add a new TODO list (retaining some of the old items) split
into items which absolutely must be fixed before the driver can
be moved out of staging:
1. Conflicting hw-ids with regular sensor drivers
2. Private userspace API stuff
As well as a list of items which also definitely needs to be fixed
but which could also be fixed after moving the driver out of staging.

Not all functions used in gmin_get_var_int() update len to the actual
length of the returned string. So len may still have its initial value
of the length of val[] when "val[len] = 0;" is run to ensure 0 termination.
If this happens we end up writing one beyond the bounds of val[], fix this.
Note this is a quick fix for this since the entirety of
atomisp_gmin_platform.c will be removed once all atomisp sensor
drivers have been moved over to runtime-pm + v4l2-async device
registration.
