.. SPDX-License-Identifier: GPL-2.0 I²C drivers =========== The I²C (Inter-Integrated Circuit) bus is a three-wires bus used internally at the media cards for communication between different chips. While the bus is not visible to the Linux Kernel, drivers need to send and receive commands via the bus. The Linux Kernel driver abstraction has support to implement different drivers for each component inside an I²C bus, as if the bus were visible to the main system board. One of the problems with I²C devices is that sometimes the same device may work with different I²C hardware. This is common, for example, on devices that comes with a tuner for North America market, and another one for Europe. Some drivers have a ``tuner=`` modprobe parameter to allow using a different tuner number in order to address such issue. The current supported of I²C drivers (not including staging drivers) are listed below.
