commit 9a472613f5bccf1b36837423495ae592a9c5182f upstream
The soc/fsl/dpio driver will perform a soc_device_match()
to determine the optimal cache settings for a given CPU core.
If FSL_GUTS is not enabled, this search will fail and
the driver will not configure cache stashing for the given
DPIO, and a string of "unknown SoC" messages will appear:
fsl_mc_dpio dpio.7: unknown SoC version
fsl_mc_dpio dpio.6: unknown SoC version
fsl_mc_dpio dpio.5: unknown SoC version
Fixes: 51da14e96e9b ("soc: fsl: dpio: configure cache stashing destination")
