3 | Maxim Integrated MAX2175 RF to bits tuner driver |
4 | ================================================ | |
5 | ||
6 | The MAX2175 driver implements the following driver-specific controls: | |
7 | ||
8 | ``V4L2_CID_MAX2175_I2S_ENABLE`` | |
9 | ------------------------------- | |
10 | Enable/Disable I2S output of the tuner. This is a private control | |
11 | that can be accessed only using the subdev interface. | |
a405ed85 | 12 | Refer to Documentation/media/kapi/v4l2-controls.rst for more details. |

24 | ``V4L2_CID_MAX2175_HSLS`` | |
25 | ------------------------- | |
26 | The high-side/low-side (HSLS) control of the tuner for a given band. | |

36 | - The LO frequency position is above the desired frequency. | |
37 | ||
38 | ``V4L2_CID_MAX2175_RX_MODE (menu)`` | |
39 | ----------------------------------- | |
40 | The Rx mode controls a number of preset parameters of the tuner like | |
41 | sample clock (sck), sampling rate etc. These multiple settings are | |
42 | provided under one single label called Rx mode in the datasheet. The | |
43 | list below shows the supported modes with a brief description. | |
