From 83c7321b7f2a4cf3d033c0c79c10fefe168851d0 Mon Sep 17 00:00:00 2001 From: pengjunhao5 Date: Thu, 10 Mar 2022 17:18:08 +0800 Subject: gelarshie: Initial EC image Copy the Coachz reference board EC files into a new directory name for the gelarshie variant. Changed the pmic LN9310 and remove WLC. TCPC and BC 1.2 use the same i2c bus.
