+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.
