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.

``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.
