From da89dba1a0c69ed01e33ebf41327b90993d08492 Mon Sep 17 00:00:00 2001 From: Paul Zimmerman Date: Thu, 15 Jan 2015 02:45:12 +0000 Subject: [PATCH] usb: phy: make GPIOs optional for the generic phy The use of GPIOs should be optional for the generic phy, otherwise the Altera SOCFPGA platform at least is broken. Fixes breakage caused by a combination of e9f2cefb0cd "usb: phy: generic: migrate to gpio_desc" and 135b3c4304d "usb: dwc2: platform: add generic PHY framework support".
