From ba345b77fae7054d0cbd033283c47033e45db6d8 Mon Sep 17 00:00:00 2001 From: Frank Li Date: Wed, 5 Jul 2023 16:59:53 -0400 Subject: [PATCH] arm64: dts: imx8mp: remove arm,primecell-periphid at etm nodes The reg size of etm nodes is incorrectly set to 64k instead of 4k. This leads to a crash when calling amba_read_periphid(). After corrected reg size, amba_read_periphid() retrieve the correct periphid. arm,primecell-periphid were removed from the etm nodes.
