From cbbdcb330d7885824623014e6e589a4eebe9d9d4 Mon Sep 17 00:00:00 2001 From: Yidi Lin Date: Tue, 22 Sep 2020 19:45:41 +0800 Subject: soc/mediatek/mt8192: Add board-specific regulator APIs To enable DVFS, DRAM driver needs to access four different regulators that SoC can't access directly and need board-specific implementations. To support that we need to define the getter and setter APIs for those regulators.
