From 3f6e2482e04b62ce74141cb0a8b9132d6877dd57 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Thu, 13 Jun 2013 16:18:11 +0200 Subject: [PATCH v5 1/3] arm: Add basic clocks for Rockchip rk3066a SoCs This adds a basic clock setup for rk3066a SoCs, currently only using dummy clocks to satisfy drivers requiring clocks.. Clocks whose rates need to be known are supplied by fixed-rate "dummy"-clocks that provide the correct rate. This is uncritical insofar that the only bootloader currently in existence for Rockchip devices is the propietary Rockchip one that always setups the clocks in the necessary and same way.
