From a5215c4eb3a4cbe0ef32257c4da2e5a6e0febdef Mon Sep 17 00:00:00 2001 From: Reka Norman Date: Fri, 22 Sep 2023 15:26:54 +1000 Subject: soc/intel: Move USB wake methods to a common ASL file The ACPI methods for enabling USB wake are identical on ADL, CNL and SKL. Move them to a common ASL file so they can be reused more easily on other SoCs. Also move the USB_PORT_WAKE_ENABLE macro used to create enable bitmasks in devicetree to a common header. BUG=b:300844110 TEST=Use abuild to build kinox, puff, and fizz with and without this change. Check the generated dsdt.aml is unchanged.
