From d95425c51a6cd11a9a22d007afb66ef841359e96 Mon Sep 17 00:00:00 2001 From: Tristan Shieh Date: Fri, 26 Apr 2019 11:36:13 +0800 Subject: mediatek/mt8183: Set CPU frequency to 1417MHz With the default CPU voltage (0.8v), CPU frequency should be 1417Mhz at most. We have to raise CPU frequency to 1989MHz after increasing CPU voltage to 1.05v in romstage.
