From c5614df7ffa74d2fcb591eb4e9008ca38f0bc8c1 Mon Sep 17 00:00:00 2001 From: Benjamin Rood Date: Fri, 30 Oct 2015 10:53:28 -0400 Subject: [PATCH] pm80xx: set PHY profiles for ATTO 12Gb SAS controllers PHY profiles are not saved in NVRAM on ATTO 12Gb SAS controllers. Therefore, in order for the controller to function in a wide range of configurations, the PHY profiles must be statically set. This patch provides the necessary functionality to do so.
