[PATCH v1] arm64: dts: imx8mx: move soc device into ocotp
From: Robin Gong
Date: Mon Jun 07 2021 - 05:48:44 EST
move soc device into ocotp device node instead of the parent device
of the all devices which located in 'soc@0', otherwise, all probed
children devices will be reorder to dmp_list again once 'imx8mx-soc'
device defered probed, which may break driver's suspend/resume sequence,
such as imx_spdif and fsl_spdif, hence the later would suspended before
the former as below and endless interrupt may never be handled since
clock has been disabled already in the later.
