1 | Maxim Integrated MAX2175 RF to bits tuner driver |
2 | ================================================ | |
3 | ||
4 | The MAX2175 driver implements the following driver-specific controls: | |
5 | ||
6 | ``V4L2_CID_MAX2175_I2S_ENABLE`` | |
7 | ------------------------------- | |
8 | Enable/Disable I2S output of the tuner. This is a private control | |
9 | that can be accessed only using the subdev interface. | |
a405ed85 | 10 | Refer to Documentation/media/kapi/v4l2-controls.rst for more details. |

20 | - I2S output is enabled. | |
21 | ||
22 | ``V4L2_CID_MAX2175_HSLS`` | |
23 | ------------------------- | |
24 | The high-side/low-side (HSLS) control of the tuner for a given band. | |

31 | * - ``(0)`` | |
32 | - The LO frequency position is below the desired frequency. | |
33 | * - ``(1)`` | |
34 | - The LO frequency position is above the desired frequency. | |
35 | ||
36 | ``V4L2_CID_MAX2175_RX_MODE (menu)`` | |
37 | ----------------------------------- | |
38 | The Rx mode controls a number of preset parameters of the tuner like | |
39 | sample clock (sck), sampling rate etc. These multiple settings are | |
40 | provided under one single label called Rx mode in the datasheet. The | |
41 | list below shows the supported modes with a brief description. | |

51 | samples/sec with a 10.24 MHz sck. | |
52 | * - ``"DAB 1.2" (1)`` | |
53 | - This configures VHF band with a sample rate of 2.048 million | |
54 | samples/sec with a 32.768 MHz sck. | |

60 | * - ``"DAB 1.2" (1)`` | |
61 | - This configures FM band with a sample rate of 0.372 million | |
62 | samples/sec with a 7.441875 MHz sck. |
