* ARM: shmobile: porter: initial device treeSergei Shtylyov2015-10-022-0/+55
| | | | | | | | | | | Add the initial device tree for the R8A7791 SoC based Porter low cost board (which is a slightly modified version of the Henninger board). SCIF0 serial port support is included, so that the serial console can work.
