From 9171f1ab8d9164f909f794a8a308a944ddefc74d Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Thu, 27 Aug 2015 16:48:11 -0700 Subject: skylake: ACPI: Remove itss.asl and cleanup irqlinks.asl Move the itss.asl code that was exporting PIRQ routing control registers into irqlinks.asl and use the PCR access methods to find the appropriate address. At the same time clean up the code in irqlinks.asl to follow formatting rules. Also now that the GPIO code in itss.asl is unused the file can be removed.
