   4 Subject: [PATCH] Revert "ata: ahci: mvebu: Make SATA PHY optional for Armada
   5  3720"

  10 This reverts commit 45aefe3d2251e4e229d7662052739f96ad1d08d9.
  11
  12 Armada 3720 PHY driver (phy-mvebu-a3700-comphy.c) does not return
  13 -EOPNOTSUPP from phy_power_on() callback anymore.
  14
  15 So remove AHCI_HFLAG_IGN_NOTSUPP_POWER_ON flag from Armada 3720 plat data.
  16
  17 AHCI_HFLAG_IGN_NOTSUPP_POWER_ON is not used by any other ahci driver, so
  18 remove this flag completely.
