From cdcfcac968a1ec648434892b6addd80e66a5a892 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Thu, 17 Oct 2013 22:50:59 -0700 Subject: ASoC: rcar: add rsnd_scu_hpbif_is_enable() Current SSI needs RSND_SSI_DEPENDENT flag to decide dependent/independent mode. And SCU needs RSND_SCU_USE_HPBIF flag to decide HPBIF is enable/disable. But these 2 means same things. This patch adds new rsnd_scu_hpbif_is_enable() function, and merges above methods.
