From 79d66a6ac117dc4978c3ee66e342ad06411d390c Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Fri, 6 Dec 2019 21:41:58 -0700 Subject: x86: Move UCLASS_IRQ into a separate file Update this uclass to support the needs of the Apollo Lake ITSS. It supports four operations. Move the uclass into a separate directory so that sandbox can use it too. Add a new Kconfig to control it and enable this on x86.
