From 451af33552286b426940a32126bd3ece243223a3 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Mon, 4 Jun 2007 17:23:24 -0700 Subject: [PATCH] sky2: enable clocks before probe Catch-22: On Yukon EX (88E8071) need to have internal clocks enabled before reading chip id. It is harmless on other chips.
