From 8feb3680bd0363a8d784fa0d065e0a6cdc9e0cff Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Wed, 28 Dec 2016 14:56:52 -0800 Subject: usb: chipidea: Add platform flag for wrapper phy management The ULPI phy on qcom platforms needs to be initialized and powered on after a USB reset and before we toggle the run/stop bit. Otherwise, the phy locks up and doesn't work properly. Therefore, add a flag to skip any phy power management in the core layer, leaving it up to the glue driver to manage.
