Subject: [PATCH 1/2] ASoC: rsnd: Fix parent SSI start/stop in multi-SSI mode
Date: Wed, 15 Apr 2020 16:10:16 +0200	[thread overview]
Message-ID: <20200415141017.384017-2-matthias.blankertz@cetitec.com> (raw)
In-Reply-To: <20200415141017.384017-1-matthias.blankertz@cetitec.com>

The parent SSI of a multi-SSI setup must be fully setup, started and
stopped since it is also part of the playback/capture setup. So only
skip the SSI (as per commit 203cdf51f288 ("ASoC: rsnd: SSI parent cares
SWSP bit") and commit 597b046f0d99 ("ASoC: rsnd: control SSICR::EN
correctly")) if the SSI is parent outside of a multi-SSI setup.
