From 604f69868ffc47c4cfc7623c83ccff89a0afcee8 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Wed, 7 Jun 2017 09:46:52 +0200 Subject: sb/intel/bd82x6x: Fill in acpi_name MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fill in acpi_name to return proper ACPI names. To be used with SSDT generators. The ACPI names have to match those already used in ASL code. By providing the ACPI name it can be retrieved by the acpi_device_name() method and doesn't need to be hardcoded in SSDT generators any more. HDEF is defined in sb/intel/bd82x6x/acpi/audio.asl. LPCB is defined in sb/intel/bd82x6x/acpi/lpc.asl. RP0* is defined in sb/intel/bd82x6x/acpi/pcie.asl. SATA is defined in sb/intel/bd82x6x/acpi/sata.asl. SBUS is defined in sb/intel/bd82x6x/acpi/smbus.asl. EHC? is defined in sb/intel/bd82x6x/acpi/usb.asl. XHC is defined in sb/intel/bd82x6x/acpi/usb.asl.
