Subject: [PATCH 18/22] topology: ABI - Update manifest to ABI v5
Date: Thu, 27 Oct 2016 15:14:32 +0800	[thread overview]
Message-ID: <ff88fb770eec5bd9fd2f3a8909e46c66c0d51ac9.1477549962.git.mengdong.lin@linux.intel.com> (raw)
In-Reply-To: <cover.1477549962.git.mengdong.lin@linux.intel.com>

From: Mengdong Lin <mengdong.lin@linux.intel.com>

Add the following fields to manifest:
- a count of physical DAIs. Later patches will add new ABI types for
  physical DAIs.
- some reserved fields for future extenstion.

Pump ABI version to 5.

Kerel will handle this ABI update in a backward compatible way, via patch
'ASoC: topology: Make manifest backward compatible from ABI v4'.

Signed-off-by: Mengdong Lin <mengdong.lin@linux.intel.com>
