V4L/DVB (12548): v4l2: video device: Add V4L2_CTRL_CLASS_FM_TX controls
This patch adds a new class of extended controls. This class is intended to support FM Radio Modulators properties such as: rds, audio limiters, audio compression, pilot tone generation, tuning power levels and preemphasis properties.
