From 53d2a715c24034ee4017f3c15c82bb4a53a07da5 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 11 Nov 2015 18:24:21 +0100 Subject: phy: Add Tegra XUSB pad controller support Add a new driver for the XUSB pad controller found on NVIDIA Tegra SoCs. This hardware block used to be exposed as a pin controller, but it turns out that this isn't a good fit. The new driver and DT binding much more accurately describe the hardware and are more flexible in supporting new SoC generations.
