From 9a472613f5bccf1b36837423495ae592a9c5182f Mon Sep 17 00:00:00 2001 From: Mathew McBride matt@traverse.com.au Date: Thu, 1 Sep 2022 05:21:49 +0000 Subject: [PATCH] soc: fsl: select FSL_GUTS driver for DPIO
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
