From b193d52653b025c416bca44b2e44d69ae1301c48 Mon Sep 17 00:00:00 2001 From: Keith Short Date: Wed, 11 Nov 2020 12:57:41 -0700 Subject: halvor: Enabling sourcing of 6A on type-C ports To support USB4, source a total of 6A on the type-C ports. This ensures that if the first device requests 3A (15W), the chromebook continues to source 3A even after a second device is connected.
