Subject: [PATCH 6.1.y 5/6] ASOC: codecs: ES8326: Add calibration support for version_b
Date: Wed, 17 Apr 2024 11:31:15 +0300 [thread overview]
Message-ID: <20240417083116.608610-6-kovalev@altlinux.org> (raw)
In-Reply-To: <20240417083116.608610-1-kovalev@altlinux.org>
From: Zhu Ning <zhuning0077@gmail.com>
Commit 0663286e58e6f611f3578b5e63e1faa576d139fd upstream.
Version_b requires a new way of calibrating headset offset. A new
calibration function is added.
