From fcb5270d54b9f0eb60deaa942e3475ef59cf5f0f Mon Sep 17 00:00:00 2001 From: Mohammed Habibulla Date: Tue, 29 Oct 2013 11:13:14 -0700 Subject: google/panther: Disable LPSS I2C controllers There is nothing attached to these devices so we can disable them as well as the function 0 DMA controller. Also remove the EC SMI/SCI mappings since there is no EC.
