From f40043b368ae787837ef659728f0b08bd34f5317 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Thu, 25 Apr 2019 17:34:42 +0200 Subject: dt-bindings: phy: tegra-xusb: List PLL power supplies These power supplies provide power for various PLLs that are set up and driven by the XUSB pad controller. These power supplies were previously improperly added to the PCIe and XUSB controllers, but depending on the driver probe order, power to the PLLs will not be supplied soon enough and cause initialization to fail.
