Subject: [PATCH 4/7] phy: phy-mtk-tphy: disable hardware efuse when set INTR
Date: Fri, 19 Aug 2022 17:13:41 +0800 [thread overview]
Message-ID: <20220819091344.2274-4-chunfeng.yun@mediatek.com> (raw)
In-Reply-To: <20220819091344.2274-1-chunfeng.yun@mediatek.com>
INTR's value is able autoload from hardware efuse by default, when
software tries to update its value, should disable hardware efuse
firstly.
