From ed90f91a17112d474909bd820f1bb65a5480959d Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Fri, 31 Mar 2017 22:06:01 +0900 Subject: ALSA: fireface: add model specific structure RME Fireface series has several models and their specifications are different. Currently, we find no way to retrieve the specifications from actual devices and need to implement them in this driver. This commit adds a structure to describe model specific data. This structure has an identical name for each unit, and maximum number of data channels in each mode. I'll describe about the mode in following commits.
