This adds a device tree definition file for LEGO MINDSTORMS EV3. What is working: * Pin muxing * Pinconf * GPIOs * MicroSD card reader * UART on input port 1 * Buttons * LEDs * Poweroff/reset * Flash memory * EEPROM * USB host port * USB peripheral port What is not working/to be added later: * Speaker - have patch submitted to get pwm-beeper working - maybe someday it will have a real sound driver that uses PRU * A/DC chip - have driver submitted and accepted - waiting for ack on device tree bindings * Display - waiting for "simple DRM" to be mainlined * Bluetooth - needs new driver for sequencing power/enable/clock * Input and output ports - need some sort of new phy or extcon driver as well as PRU UART and PRU I2C drivers * Battery indication - needs new power supply driver Note on flash partitions: These partitions are based on the official EV3 firmware from LEGO. It is expected that most users of the mainline kernel on EV3 will be booting from an SD card while retaining the official firmware in the flash memory. Furthermore, the official firmware uses an ancient U-Boot (2009) that has no device tree support. So, it makes sense to have this partition table in the EV3 device tree file. In the unlikely case that anyone does create their own firmware image with different partitioning, they can use a modern U-Boot in their own firmware image that modifies the device tree with the custom partitions.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
