Subject: [PATCH 2/2] dt-bindings: usb: Bring back phy-names

From: Maxime Ripard <[email-masked]>
Date: Wed, 2 Oct 2019 13:26:51 +0200

While the original bindings that were superseeded by the YAML schemas
didn't mention that phy-names was needed, it turns out that phy-names is
required if phys is set according to phy/phy-bindings.txt.

Let's add back those properties.

Fixes: 14ec072a19ad ("dt-bindings: usb: Convert USB HCD generic binding to YAML")
Fixes: c93bcace1098 ("dt-bindings: usb: Convert the generic OHCI binding to YAML")
Fixes: c3e2485d5f4f ("dt-bindings: usb: Convert the generic EHCI binding to YAML")
