Subject: [PATCH 14/18] phy: mediatek: mipi: mt8173: use FIELD_PREP to prepare bits field
Date: Tue, 20 Sep 2022 17:00:34 +0800	[thread overview]
Message-ID: <20220920090038.15133-15-chunfeng.yun@mediatek.com> (raw)
In-Reply-To: <20220920090038.15133-1-chunfeng.yun@mediatek.com>

Use FIELD_PREP() macro to prepare bits field value, then no need define
macros of bits offset.
