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.
