Subject: [PATCH 1/2] ASoC: uniphier: add syscon property to binding document
Date: Fri, 16 Mar 2018 16:08:12 +0900	[thread overview]
Message-ID: <20180316070813.17969-2-suzuki.katsuhiro@socionext.com> (raw)
In-Reply-To: <20180316070813.17969-1-suzuki.katsuhiro@socionext.com>

This patch adds syscon property for specifying soc-glue core into
DT binding documentation.

Currently, soc-glue core is used for changing the state of S/PDIF
signal output pin to signal output state or Hi-Z state. If you don't
need to use features on soc-glue described above you can ommit this
property.
