From 76d3341b63a2ba173e7163c48918ec45934df98b Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Sat, 15 Apr 2017 10:05:09 -0700 Subject: mfd: omap-usb-tll: Configure ULPIAUTOIDLE The idle mode needs to be only disabled for UTMIAUTOIDLE while ULPIAUTOIDLE can be enabled. This matches the TLL_CHANNEL_CONF_i register configuration for ehci-tll in the Motorola Linux kernel tree for Wrigley 3G LTE modem on droid 4 and the modem still stays responsive.
