	Configure the controller, leaving it disabled.
void(*	enable )(const struct pbl_i2c_bus *bus)
	Enable the controller.
void(*	disable )(const struct pbl_i2c_bus *bus)
	Disable the controller.
bool(*	is_busy )(const struct pbl_i2c_bus *bus)
	Check whether the controller is busy.
void(*	start_transfer )(const struct pbl_i2c_bus *bus)
	Start the current transfer.
void(*	abort_transfer )(const struct pbl_i2c_bus *bus)
	Abort the current transfer.

Detailed Description

Bus driver operations.

Called with the bus lock held. The class layer owns locking, retries and timeouts; the driver moves the current transfer over the wire and reports its outcome with pbl_i2c_bus_event().
