Subject: [PATCH] usb: xhci: tegra: Remove PLL power supplies
Date: Fri, 12 Jun 2020 16:02:05 +0200 [thread overview]
Message-ID: <20200612140205.2342900-1-thierry.reding@gmail.com> (raw)
From: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>
The Tegra XUSB controller driver doesn't need to control the PLL power
supplies directly, but rather uses the pads provided by the XUSB pad
controller, which in turn is responsible for supplying power to the
PLLs.
