Subject: [PATCH 22/24] ASoC: SOF: topology: Get HDA rate and channels from topology
Date: Wed, 15 Apr 2020 15:28:14 -0500	[thread overview]
Message-ID: <20200415202816.934-23-pierre-louis.bossart@linux.intel.com> (raw)
In-Reply-To: <20200415202816.934-1-pierre-louis.bossart@linux.intel.com>

From: Bard Liao <yung-chuan.liao@linux.intel.com>

FW interface for HDA DAI parameters was extended with information on
sampling rate and channel count in version 3.16. Align kernel header
with the FW change. This change is backwards compatible. Old firmware
will ignore the values.
