Subject: [d-kernel] [PATCH 7/9] ASOC: codecs: ES8326: Add calibration support for version_b
Date: Fri,  8 Dec 2023 20:09:37 +0300
Message-ID: <20231208170938.175868-8-kovalev@altlinux.org> (raw)
In-Reply-To: <20231208170938.175868-1-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.
