From 452503ebc7cc4cce5b9e52cf2f03255365a53234 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Sat, 24 Dec 2011 01:24:24 +0100 Subject: ARM: Orion: Eth: Add clk/clkdev support. The t_clk is moved from the shared part of the ethernet driver into the per port section. Each port can have its own gated clock, which it needs to enable/disable, as oppossed to there being one clock shared by all ports. In practice, only kirkwood supports this at the moment.
