From 8996b89d6bc98ae2f6d6e6e624a42a3f89d06949 Mon Sep 17 00:00:00 2001 From: Mark Langsdorf Date: Thu, 6 Sep 2012 16:03:30 -0500 Subject: ata: add platform driver for Calxeda AHCI controller Calxeda highbank SATA phy has intermittent problems bringing up a link with Gen3 drives. Retrying the phy hard reset can work-around this issue, but each reset also disables spread spectrum support. The reset function also needs to reprogram the phy to enable spread spectrum support. Create a new driver based on ahci_platform to support the Calxeda Highbank SATA controller.
