From 8e71ca00d48a0edb8d5be6bb6516a6d102535d7e Mon Sep 17 00:00:00 2001 From: Huayang Duan Date: Mon, 19 Aug 2019 16:22:48 +0800 Subject: [PATCH] mediatek/mt8183: Add new option for eMCP DDR Devices using eMCP may run at a high DRAM frequency (e.g., 3600Mbs) while those with discrete DRAM can only run at 3200Mbps. A new option MT8183_DRAM_EMCP is added to Kconfig for a mainboard to select, depending on whether it supports eMCP or not.
