[media] v4l2-subdev.rst: get rid of legacy functions
There are two warnings that are due to functions that has long gone: Documentation/media/kapi/v4l2-subdev.rst:417: WARNING: c:func reference target not found: v4l2_i2c_new_subdev_cfg Documentation/media/kapi/v4l2-subdev.rst:436: WARNING: c:func reference target not found: v4l2_i2c_new_probed_subdev Update the documentation to remove those.

To see which chip variants are supported you can look in the i2c driver code
|
||||
for the i2c_device_id table. This lists all the possibilities.
|
||||
|
||||
There are two more helper functions:
|
||||
|
||||
:c:func:`v4l2_i2c_new_subdev_cfg`: this function adds new irq and
|
||||
platform_data arguments and has both 'addr' and 'probed_addrs' arguments:
|
||||
if addr is not 0 then that will be used (non-probing variant), otherwise the
|
||||
probed_addrs are probed.
|
||||
|
||||
For example: this will probe for address 0x10:
|
||||
|
||||
.. code-block:: c
|
||||
|
||||
struct v4l2_subdev *sd = v4l2_i2c_new_subdev_cfg(v4l2_dev, adapter,
|
||||
"module_foo", "chipid", 0, NULL, 0, I2C_ADDRS(0x10));
|
||||
There are one more helper function:
|
||||
|
||||
:c:func:`v4l2_i2c_new_subdev_board` uses an :c:type:`i2c_board_info` struct
|
||||
which is passed to the i2c driver and replaces the irq, platform_data and addr

If the subdev supports the s_config core ops, then that op is called with
|

the irq and platform_data arguments after the subdev was setup.

|

The older :c:func:`v4l2_i2c_new_subdev` and
|

:c:func:`v4l2_i2c_new_probed_subdev` functions will call ``s_config`` as

The :c:func:`v4l2_i2c_new_subdev` function will call

:c:func:`v4l2_i2c_new_subdev_board`, internally filling a

:c:type:`i2c_board_info` structure using the ``client_type`` and the

``addr`` to fill it.
