From af2ed695cfb98a6744ec15273b50e09cc1d28a17 Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Tue, 28 Jun 2016 09:23:58 +0100 Subject: [PATCH] UPSTREAM: usb: dwc3: st: Inform the reset framework that our reset line may be shared On the STiH410 B2120 development board the MiPHY28lp shares its reset line with the Synopsys DWC3 SuperSpeed (SS) USB 3.0 Dual-Role-Device (DRD). New functionality in the reset subsystems forces consumers to be explicit when requesting shared/exclusive reset lines.
