From 4a2cfad13b95917f3e3fda742e43e87961daea3a Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Fri, 21 Oct 2016 16:40:17 -0700 Subject: arch/x86/acpigen_dsm: Add support for DSM types Currently, the only supported DSM type is I2C HID(3CDFF6F7-4267-4555-AD05-B30A3D8938DE). This provides the required callbacks for generating ACPI AML codes for different function identifiers for I2C HID.
