From 57bc4dfcb886bc79cbcc8d285ad85c49a807ac8f Mon Sep 17 00:00:00 2001 From: Keith Short Date: Wed, 11 Nov 2020 13:00:04 -0700 Subject: tglrvu_ite: Enabling sourcing of 4.5A on type-C ports To support USB4, source a total of 4.5A 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.
