Functions
: name for this bus
psb_intel_i2c_create - instantiate an Intel i2c bus using the specified GPIO reg : DRM device : driver specific output device : GPIO reg to use Creates and registers a new i2c bus with the Linux i2c layer, for use in output probing and control (e.g. DDC or SDVO control functions). Possible values for include: GPIOA GPIOB GPIOC GPIOD GPIOE GPIOF GPIOG GPIOH see PRM for details on how these different busses are used.
