From aa0929d101ddfb9e64d8febd2bd31ce1037e62ff Mon Sep 17 00:00:00 2001 From: Gaggery Tsai Date: Tue, 8 Jan 2019 15:13:25 -0800 Subject: mb/google/poppy/variant/atlas: enable USB acpi Main objective for this change is to export the bluetooth reset gpio to the kernel for use in an rf-kill operation. To do so, we enable USB acpi and define all of the USB2 devices, which includes bluetooth's reset gpio information.
