[PATCH 4/7] phy: phy-mtk-tphy: disable hardware efuse when set INTR

From: Chunfeng Yun <chunfeng.yun@mediatek.com>
Date: 2022-08-19 09:14:38
Also in: linux-devicetree, linux-mediatek, linux-phy, lkml
Subsystem: arm/mediatek usb3 phy driver, generic phy framework, the rest · Maintainers: Chunfeng Yun, Vinod Koul, Linus Torvalds

INTR's value is able autoload from hardware efuse by default, when
software tries to update its value, should disable hardware efuse
firstly.
