From: Paul Zimmerman Date: Thu, 15 Jan 2015 02:45:12 +0000 (+0000) Subject: usb: phy: make GPIOs optional for the generic phy X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=da89dba1a0c69ed01e33ebf41327b90993d08492;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git 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".
