[PATCH 21/28] ARM: shmobile: porter: initial device tree

Simon Horman horms+renesas at verge.net.au
Tue Oct 6 18:57:58 PDT 2015


From: Sergei Shtylyov <sergei.shtylyov at cogentembedded.com>

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.
