ata: sata_mv: fix disk hotplug for Armada 370/XP SoCs
commit 9013d64e661fc2a37a1742670202171c27fef4b5 upstream.
On Armada 370/XP SoCs, once a disk is removed from a SATA port, then the
re-plug events are not detected by the sata_mv driver. This patch fixes
the issue by updating the PHY speed in the LP_PHY_CTL register (0x58)
according to the SControl speed.
Note that this fix is only applied if the compatible string
"marvell,armada-370-sata" is found in the SATA DT node.
