From 26b8aa458c7d99181ceb07f27da9bd7d94185e35 Mon Sep 17 00:00:00 2001 From: Robert Baldyga Date: Thu, 6 Aug 2015 14:11:15 +0200 Subject: usb: musb: gadget: add musb_match_ep() function Add 'match_ep' callback to utilize chip-specific knowledge in endpoint matching process. Function does the same that was done by chip-specific code inside of epautoconf. Now this code can be removed from there to separate generic code from platform specific logic.
