From b31f11d036e689ba9e60d581ffe8e032a6305da9 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Fri, 16 Jun 2017 01:38:50 +0000 Subject: ASoC: simple-card-utils: add asoc_simple_card_of_parse_widgets() Current simple card drivers are parsing widgets on each own driver (only simple-card at this point, but will be supported on all drivers) Encapsulation is one of simple card util's purpose. Let's add asoc_simple_card_of_parse_widgets for it.
