Maxim Integrated MAX2175 RF to bits tuner driver |
|
================================================ |
|
|
|
The MAX2175 driver implements the following driver-specific controls: |
|
|
|
``V4L2_CID_MAX2175_I2S_ENABLE`` |
|
------------------------------- |
|
Enable/Disable I2S output of the tuner. This is a private control |
|
that can be accessed only using the subdev interface. |
|
Refer to Documentation/driver-api/media/v4l2-controls.rst for more details. |

|
* - ``(0)`` |
|
- I2S output is disabled. |
|
* - ``(1)`` |
|
- I2S output is enabled. |
|
|
|
``V4L2_CID_MAX2175_HSLS`` |
|
------------------------- |
|
The high-side/low-side (HSLS) control of the tuner for a given band. |

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