From 8afd831ea00822fdc811ff640ef62352619d64c0 Mon Sep 17 00:00:00 2001 From: Alexandre Bailon Date: Fri, 4 Sep 2015 16:55:40 +0200 Subject: [PATCH] greybus: Greybus driver: add a new callbacks to driver Add connection_create and connection_destroy callbacks. ES2 can map a cport to a pair of endpoints. Because ES2 have only a few pair of endpoints, ES2 need to have access to some high level connection information such as protocol id to effectively map the cports. These callback will provide these information and help ES2 to map cports.
