From b7fd3d64e763c381de7ed57217fda3c720a98aad Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Wed, 2 May 2018 19:16:41 +0900 Subject: ALSA: dice: add proc node for stream formation Products with DICE interface in market can support variable stream formats for three levels of sampling transmission frequencies. To record these formats, a proxy structure got several fields in former commit. This commit adds a proc node to output the stream formats for debugging purpose.
