* [SCSI] isci: change sas phy timeouts from 54us to 59usMarcin Tomczak2011-08-241-0/+12
| | | | | | | | | | | | | Need the following workaround in the driver for interoperability with the older Intel SSD drives and any other SATA drive that may exhibit the same behavior. This is a corner case where SCU speed is limited to either 3G or 1.5G and the drive has a period of DC idle when it switches speed during SATA speed negotiation. Workaround :change PHYTOV[31:24] from 0x36 to 0x3B.
