From 1fa25ab2caf79b99094c3da6e09f20a35e8f01f8 Mon Sep 17 00:00:00 2001 From: David Daney Date: Thu, 7 Oct 2010 16:03:51 -0700 Subject: [PATCH 1/1] ATA: pata_octeon_cf: Use I/O clock rate for timing calculations. The creation of the I/O clock domain requires some adjustments. Since the CF bus timing logic is clocked by the I/O clock, use its rate for delay calculations.
