From cbf1494fbcc80d363477af1efefb2380e7660a24 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 7 Mar 2016 05:08:33 +0000 Subject: ASoC: rsnd: add rsnd_src_get_in/out_rate() SRC will convert rate, and then, CMD and SSI want to know its rate (= SRC.in / SRC.out) for each purpose. Current driver is supporting only Playback, but SRC+Capture support needs more flexibility. This patch adds rsnd_src_get_in/out_rate() for it.
