Hello,
This series adds support for the Melexis 75026 and 75027 Time of Flight
camera sensors, with DT bindings in patch 7/8 and a driver in patch 8/8.
In patches 1/8, 2/8 and 3/8, I've add ToF controls as separate
ToF control class.
v4:
- fix output mode
- forbid array for menu and warn if validate_new return an error
- add enums to custom control OUTPUT_MODE
- update doc
- minor fixes
v3:
- move FMOD, TINT, PHASE_SEQ to common V4L2 as ToF common controls
- FMOD and TINT became dynamic arrays
- remove PHASE_NUM, use dynamic_array for PHASE_SEQ,
ctrl->new_elems pass number of phases
- remove leden-gpios, will be used gpio explicitly in library for now
- remade probe: use probe_new, no power on during probe
- remove autodetect and wildcard
- make all supplies to be required
- remove trigger ioctl, will add in separate patch series
- remove temperature ioctl, will add in separate patch series
- add documentation about custom ioctl
- style: 80 cols
- minor fixes device tree
v2:
- added external clock to the sensor
- added all regulators required by the sensor
- added posibility to choose sensor type in device tree
- added prefixes to all custom types in device tree and driver as well
- style fixes

Define names, flags and types of TOF controls. *dims* is driver specific.
It also means, that it is not possible to use new_std for arrays.

+***************************************
+Time of Flight Camera Control Reference
+***************************************
+
+The Time of Flight class includes controls for digital features
+of the TOF sensor.
+
+TOF sensor is a receiver chip. Each pixel in the sensor measures the travel time
+of light to that pixel and hence the distance to the object seen by that pixel.
+There are different types of TOF sensors. Direct TOF sensors (also known
+as Lidars) send a single pulse and measure direct time of flight.
+Another type of TOF is indirect TOF sensors, which emit continuous wave
+(could be radio or infrared) and then measure phase shift of reflected light.
+The sensor modulates outgoing light and then collects reflected photons
+as an electric charge with modulated pattern. Knowing the frequency of
+the pattern you can calculate the real distance.
+
+For more information about TOF sensors see
+`TOF <https://en.wikipedia.org/wiki/Time-of-flight_camera>`__ from Wikipedia.
+Also, there are other nice explanations from vendors about indirect TOF:
+`Microsoft <https://devblogs.microsoft.com/azure-depth-platform/understanding-indirect-tof-depth-sensing/>`__,
+`Melexis <https://media.melexis.com/-/media/files/documents/application-notes/time-of-flight-basics-application-note-melexis.pdf>`__,
+`TI <https://www.ti.com/lit/wp/sloa190b/sloa190b.pdf?ts=1657842732275&ref_url=https%253A%252F%252Fwww.google.com%252F>`__.

+
+Time of Flight Camera Control IDs
+=================================
+
+``V4L2_CID_TOF_CLASS (class)``
+ The TOF class descriptor. Calling :ref:`VIDIOC_QUERYCTRL` for
+ this control will return a description of this control class.
+
+``V4L2_CID_TOF_PHASE_SEQ (dynamic array u16)``
+ Change the shift between illumination and sampling for each phase
+ in degrees. The distance / amplitude (confidence) pictures are obtained
+ by merging 3..8 captures of the same scene using different phase shifts
+ (some TOF sensors use different frequency modulations).
+
+ The size of dynamic array specify the number of captures.
+ Also driver may decide whether V4L2_CID_TOF_FREQ_MOD and
+ V4L2_CID_TOF_TIME_INTEGRATION should change the number
+ of captures or rely on V4L2_CID_TOF_PHASE_SEQ control.
+ The maximum size of the array is driver specific.
+
+``V4L2_CID_TOF_FREQ_MOD (dynamic array u8)``
+ The control sets the modulation frequency (in Mhz) for each phase.
+ The maximum array size is driver specific.
+
+``V4L2_CID_TOF_TIME_INTEGRATION (dynamic array u16)``
+ The control sets the integration time (in us) for each phase.
+ The maximum array size is driver specific.

For V4L2_CID_TOF_TINT, which is dynamic array, it is required to use
__v4l2_ctrl_modify_range. So the idea is to use type_ops instead of u64
from union. It will allow to work with any type.

+Melexis mlx7502x ToF camera sensor driver
+=========================================
+
+The mlx7502x driver implements the following driver-specific controls:
+
+``V4L2_CID_MLX7502X_OUTPUT_MODE (menu)``
+----------------------------------------
+ The sensor has two taps, which gather reflected light: A and B.
+ The control sets the way data should be put in a buffer. The most
+ common output mode is A-B which provides the best sunlight robustness.
+
+.. flat-table::
+ :header-rows: 0
+ :stub-columns: 0
+ :widths: 1 4
+
+ * - ``V4L2_MLX7502X_OUTPUT_MODE_A_MINUS_B``
+ - tap A minus tap B
+ * - ``V4L2_MLX7502X_OUTPUT_MODE_A_PLUS_B``
+ - tap A plus tap B
+ * - ``V4L2_MLX7502X_OUTPUT_MODE_A``
+ - only tap A
+ * - ``V4L2_MLX7502X_OUTPUT_MODE_B``
+ - only tap B
+ * - ``V4L2_MLX7502X_OUTPUT_MODE_A_AND_B``
+ - tap A and tap B (this config will change PAD format)

Hi All,
This is a gentle reminder about the patch series for ToF camera.
Thanks.

Hi Volodomyr,
I'm not sure I'm relevant, but since we discussed a bit about controls
in the first version feel free to add my tag for patch 1, 2, and 3:
Acked-By: Benjamin Mugnier <benjamin.mugnier@foss.st.com>
Thank you for your work.

Hi Benjamin,
> By the way, was the mailing list dropped from cc by mistake ?
No, I just wanted to send a remind about the patch to Sakari and Laurent.
Now it looks that this thread became more technical, so I am adding cc again.

Ok, then I'll redo in next version.
