From 2eb8801650b315394ca376a56be2971c867aa9ec Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Tue, 12 Apr 2016 16:53:39 +0300 Subject: usb: dwc3: gadget: add a pointer to endpoint registers By adding a pointer to endpoint registers' base address, we can avoid using our controller-wide struct dwc3 pointer for everything. At some point this will allow us to have per-endpoint locks which will, in turn, let us queue requests to separate endpoints in parallel. Because of this change our debugfs interface and io accessors need to be changed accordingly.
