From 3bb2f843c0e7f69385e65448fae38d78c208e699 Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Fri, 28 Sep 2018 15:11:49 +0100 Subject: [PATCH] soc/tegra: pmc: Don't power-up XUSB power-domains Now that the Tegra xHCI driver manages the XUSB power-domains itself, remove the code to power-up the power-domains used by the xHCI device from the PMC driver on boot.
