From e32da955b3a4e9674c6c5012e895c79c2696032e Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Thu, 27 Aug 2015 17:09:02 -0700 Subject: skylake: ACPI: Clean up and fix XHCI ACPI Device - Remove the old workarounds for XHCI from broadwell - Add PMC device to expose bits needed for XHCI workarounds - Implement the new workarounds for XHCI, the first will set a bit in the XHCI MMIO and the second will send a message to the PMC if a bit is set indicating the workaround is available. - Clean up the HS/SS port defines and remove unnecessary methods to determine the port count since we only support SPT-LP.
