Hello all,

This email provides updated patches for the Melexis 75026 and 75027 Time of Flight
camera sensors. In version 6, there are fixes and improvements which listed below.
A key addition is trigger mode, introduced in patches 1/10 and 2/20.
This allows userspace applications to trigger frames with more precise control.

These patches have been successfully tested on Trenz TE0820 board.

v6:
- fix step of roi and compose
- remove redundant register set on mipi configuration
- add V4L2_CID_CAMERA_TRIGGER
- add V4L2_CID_CAMERA_TRIGGER_MODE
- implemented trigger mode in the driver
- use subdev state api
- add holding for VFLIP and HFLIP
- remade frame interval

v5:
- MHz to Hz for V4L2_CID_TOF_FREQ_MOD

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
