From 9ee02095fa1b5c532f758e287401423138687b56 Mon Sep 17 00:00:00 2001 From: Yidi Lin Date: Tue, 22 Sep 2020 19:56:20 +0800 Subject: mb/google/asurada: Implement board-specific regulator controls Currently, five regulator controls are implemented for DRAM calibration and DVFS feature. The regulators for VCORE and VM18 are controlled by MT6359. The reguatlors for VDD1, VDD2 and VMDDR are controlled by MT6360 via EC.
