Subject: [PATCH 2/8] ARM: tegra: apalis: Move PLL power supplies to XUSB pad controller
Date: Thu,  4 Apr 2019 13:25:05 +0200	[thread overview]
Message-ID: <20190404112511.28118-2-thierry.reding@gmail.com> (raw)
In-Reply-To: <20190404112511.28118-1-thierry.reding@gmail.com>

From: Thierry Reding <treding@nvidia.com>

The XUSB pad controller is responsible for supplying power to the PLLs
used to drive the various USB, PCI and SATA pads. Move the PLL power
supplies from the PCIe and XUSB controllers to the XUSB pad controller
to make sure they are available when needed.
