The TPS65910/1 Linux drivers contain support for the I2C bus framework. Additional driver files support the Linux regulator framework to manage the output regulation of the IC and the Linux GPIO framework to support adding the IC's GPIO's to the system. In addition to the power resources, the Linux drivers contain support for the Linux RTC framework.
