From 7a9b248446dfd7c2d65030159e5c152a911aaf42 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Tue, 14 Mar 2017 17:39:42 -0700 Subject: [PATCH] ARM: dts: omap4-droid4: Configure EHCI so modems can be accessed Droid 4 has two modems, mdm6600 and w3glte. Both are on the HCI USB controller. Let's add a configuration for the HCI so the modems can be enabled. Note that the modems still need additional GPIO based configuration.
