THine THP7312 ISP driver

The THP7312 driver implements the following driver-specific controls:

V4L2_CID_THP7312_LOW_LIGHT_COMPENSATION Enable/Disable auto-adjustment, based on lighting conditions, of the frame rate when auto-exposure is enabled.

V4L2_CID_THP7312_AUTO_FOCUS_METHOD Set method of auto-focus. Only takes effect when auto-focus is enabled.

.. flat-table::
    :header-rows:  0
    :stub-columns: 0
    :widths:       1 4

    * - ``0``
      - Contrast-based auto-focus
    * - ``1``
      - PDAF
    * - ``2``
      - Hybrid of contrast-based and PDAF

Supported values for the control depend on the camera sensor module
connected to the THP7312. If the module doesn't have a focus lens actuator,
this control will not be exposed by the THP7312 driver. If the module has a
controllable focus lens but the sensor doesn't support PDAF, only the
contrast-based auto-focus value will be valid. Otherwise all values for the
controls will be supported.

V4L2_CID_THP7312_NOISE_REDUCTION_AUTO Enable/Disable auto noise reduction.

V4L2_CID_THP7312_NOISE_REDUCTION_ABSOLUTE Set the noise reduction strength, where 0 is the weakest and 10 is the strongest.
