From 2f129bf4aab684bef1e82e747b709a5025ecb698 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Thu, 15 Dec 2011 08:15:07 +0100 Subject: ARM: Orion: Add clocks using the generic clk infrastructure. Add tclk as a fixed rate clock for all platforms. In addition, on kirkwood, add a gated clock for most of the clocks which can be gated.
