From: Felipe Balbi Date: Thu, 6 Nov 2014 17:32:35 +0000 (-0600) Subject: arm: boot: dts: am4372: enable dwc3 suspend PHY quirk X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=60f0e628c9940dc59463e986ddfa2c9e74ea89bb;p=openwrt%2Fstaging%2Fblogic.git arm: boot: dts: am4372: enable dwc3 suspend PHY quirk Whenever Suspend PHY bit is set on AM437x devices, USB will not work due to Set EP Configuration command always failing. This was only found after a recent commit 2164a47 (usb: dwc3: set SUSPHY bit for all cores, which will be merged for v3.19) added a missing *required* step to dwc3 initialization. Synopsys Databook requires that we enable Suspend PHY bit after initialization but that, unfortunately, breaks AM437x.
