The module consists of a Tegra 3 SoC, two PMICs, 1 or 2 GB of DDR3L RAM, eMMC, an LM95245 temperature sensor chip, an i210 resp. i211 gigabit Ethernet controller, an STMPE811 ADC/touch controller as well as two MCP2515 CAN controllers. Furthermore, there is an SGTL5000 audio codec which is not yet supported. Anything that is not self contained on the module is disabled by default. The device tree for the Evaluation Board includes the modules device tree and enables the supported peripherals of the carrier board (the Evaluation Board supports almost all of them). While at it also add the device tree binding documentation for Apalis T30 as well as the previously missing one for the recently added Colibri T30.
