From 609adde838f4557f9d209b0432f4bac5c5eb5e86 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 19 Mar 2015 17:08:07 -0700 Subject: phy: Add a driver for dm816x USB PHY Add a minimal driver for dm816x USB. This makes USB work on dm816x without any other changes needed as it can use the existing musb_dsps glue layer for the USB controller. Note that this phy is different from dm814x and am335x.
