From 2809b31770d7fd934a748692e1922a5e613f06e5 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Sun, 20 Jan 2013 22:03:46 +0100 Subject: MIPS: ralink: adds support for RT305x SoC family Add support code for rt3050, rt3052, rt3350, rt3352 and rt5350 SOC. The code detects the SoC and registers the clk / pinmux settings.
