Subject: [PATCH] Revert "usb: host: xhci: mvebu: make USB 3.0 PHY optional for
|
|
Armada 3720"
|
|
MIME-Version: 1.0

This reverts commit 3241929b67d28c83945d3191c6816a3271fd6b85.
|
|
|
|
Armada 3720 phy driver (phy-mvebu-a3700-comphy.c) does not return
|
|
-EOPNOTSUPP from phy_power_on() callback anymore.
|
|
|
|
So remove XHCI_SKIP_PHY_INIT flag from xhci_mvebu_a3700_plat_setup() and
|
|
then also whole xhci_mvebu_a3700_plat_setup() function which is there just
|
|
to handle -EOPNOTSUPP for XHCI_SKIP_PHY_INIT.
|
|
|
|
xhci plat_setup callback is not used by any other xhci plat driver, so
|
|
remove this callback completely.
