    Subject[PATCH 5.19 007/192] soc: fsl: select FSL_GUTS driver for DPIO
    Date
    From: Mathew McBride <matt@traverse.com.au>

    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
