0003 Maxim Integrated MAX2175 RF to bits tuner driver
0004 ================================================
0005
0006 The MAX2175 driver implements the following driver-specific controls:
0007
0008 ``V4L2_CID_MAX2175_I2S_ENABLE``
0009 -------------------------------
0010 Enable/Disable I2S output of the tuner. This is a private control
0011 that can be accessed only using the subdev interface.
0012 Refer to Documentation/driver-api/media/v4l2-controls.rst for more details.

0022 - I2S output is enabled.
0023
0024 ``V4L2_CID_MAX2175_HSLS``
0025 -------------------------
0026 The high-side/low-side (HSLS) control of the tuner for a given band.

0034 - The LO frequency position is below the desired frequency.
0035 * - ``(1)``
0036 - The LO frequency position is above the desired frequency.
0037
0038 ``V4L2_CID_MAX2175_RX_MODE (menu)``
0039 -----------------------------------
0040 The Rx mode controls a number of preset parameters of the tuner like
0041 sample clock (sck), sampling rate etc. These multiple settings are
0042 provided under one single label called Rx mode in the datasheet. The
0043 list below shows the supported modes with a brief description.
