From 6bd9d959ddc3fabd84c57de41c6a1db7c400f562 Mon Sep 17 00:00:00 2001 From: "ot_zhenguo.li" Date: Fri, 24 Feb 2023 13:55:27 +0800 Subject: soc/mediatek/mt8188: Enable lastbus debug hardware Lastbus is a bus debug tool. When the bus hangs, the bus transmission information before resetting will be recorded. The watchdog cannot clear it and it will be printed out for bus hanging analysis. There are two versions for lastbus: Version 1 for MT8186, and version 2 for MT8188. BUG=b:263753374 TEST=build pass.
