From 951a6207f32fbfc7bf21f122b3a66b88fb79892c Mon Sep 17 00:00:00 2001 From: Jamie Chen Date: Mon, 20 Jan 2020 18:06:19 +0800 Subject: mb/google/puff: Add ac/dc loadline configuations According to VRTT report, add ac/dc loadline configuations in puff device tree. BUG=b:147206535 BRANCH=None TEST=build coreboot and fsp with enabled fw_debug. Flashed to puff and checked the log. All ac/dc loadline configs were set correctly.
