From 5fefcd59a84aad605d7e5f9c31d483d040fc01bd Mon Sep 17 00:00:00 2001 From: Tim Wawrzynczak Date: Tue, 28 Jun 2022 12:20:10 -0600 Subject: ec/google/chromec: Update ACPI handlers for GPU There is a new field in EC EMEM for arbitrary GPU data to be passed from EC to ACPI FW; this patch adds support for it. Also the current host event for _Q0C (EC_HOST_EVENT_USB_CHARGER) is unused, and is being repurposed in the next CL, so this patch drops the handler.
