[ Upstream commit 46db63abb79524209c15c683feccfba116746757 ]
This is currently off and that's not desirable: default imx config is meant to be generally useful for development and debugging.
Running git bisect between v5.4 and v5.5-rc1 finds this started from commit 0e4a459f56c3 ("tracing: Remove unnecessary DEBUG_FS dependency")
Explicit CONFIG_DEBUG_FS=y was earlier removed by commit c29d541f590c ("ARM: imx_v6_v7_defconfig: Remove unneeded options")
A very similar fix was required before: commit 7e9eb6268809 ("ARM: imx_v6_v7_defconfig: Explicitly restore CONFIG_DEBUG_FS")
