Subject: [PATCH 1/1] arm64: dts: imx8mp: remove arm,primecell-periphid at etm nodes
Date: Wed, 5 Jul 2023 16:59:53 -0400 [thread overview]
Message-ID: <20230705205954.4159781-1-Frank.Li@nxp.com> (raw)
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.
