From d66e64dd006dfbc08f5395e1ca674903d46fa601 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 24 Nov 2022 11:50:22 +0000 Subject: target/xtensa: Convert to 3-phase reset MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Convert the xtensa CPU class to use 3-phase reset, so it doesn't need to use device_class_set_parent_reset() any more.
