While the bus 8is not visible to the Linux Kernel, drivers need to send and receive 9commands via the bus. The Linux Kernel driver abstraction has support to 10implement different drivers for each component inside an I²C bus, as if 11the bus were visible to the main system board. 12 13One of the problems with I²C devices is that sometimes the same device may 14work with different I²C hardware. This is common, for example, on devices 15that comes with a tuner for North America market, and another one for 16Europe. Some drivers have a ``tuner=`` modprobe parameter to allow using a 17different tuner number in order to address such issue. 18 19The current supported of I²C drivers (not including staging drivers) are 20listed below. 21 22Audio decoders, processors and mixers 23------------------------------------- 24 25============ ========================================================== 26Driver Name
