[libcamera-devel] [PATCH 3/5] libcamera: camera_sensor: Rename controls() method

[Jacopo Mondi]

The CameraSensor::controls() methods returns the information relative to
the V4L2 controls registered by the sensor sub-device driver. Its
current use is to inform the IPA module of two pipelines (RkISP1 and
VIMC) about the V4L2 controls limits.

The CameraSensor class has a controls_ field, which is instead the
ControlInfoMap of libcamera controls registered by the CameraSensor
class and meant to be exported as Camera controls.

To prepare to register libcamera controls in the CameraSensor::controls_
info map, and remove any ambiguity on the intended usage of
CameraSensor::controls(), rename the method in
CameraSensor::subdevControls() and update its users in the code base.
