From 8cc8b3c14b07d03e4c702510b21d7e311049798e Mon Sep 17 00:00:00 2001 From: Sen Chu Date: Wed, 16 Aug 2023 08:44:41 +0800 Subject: soc/mediatek/mt8188: Simplify pmif init flow Based on "MediaTek_EFUSE_MT8188_Confidential A_Technical Doc.docx", MT8188G used in ChromeOS project does not support clock hardware monitor. Thus, we can simplify the initialization flow by removing the hardware default value check.
