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") Signed-off-by: Mathew McBride <matt@xxxxxxxxxxxxxxx> Reviewed-by: Ioana Ciornei <ioana.ciornei@xxxxxxx> Cc: stable@xxxxxxxxxxxxxxx Link: https://lore.kernel.org/r/20220901052149.23873-2-matt@xxxxxxxxxxxxxxx' Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx> diff --git a/drivers/soc/fsl/Kconfig b/drivers/soc/fsl/Kconfig index 07d52cafbb31..fcec6ed83d5e 100644 --- a/drivers/soc/fsl/Kconfig +++ b/drivers/soc/fsl/Kconfig @@ -24,6 +24,7 @@ config FSL_MC_DPIO tristate "QorIQ DPAA2 DPIO driver" depends on FSL_MC_BUS select SOC_BUS + select FSL_GUTS select DIMLIB help Driver for the DPAA2 DPIO object.
