From a7ab186f60785850b5af1be183867000485ad491 Mon Sep 17 00:00:00 2001 From: Andrew Jeffery Date: Mon, 7 Jun 2021 11:00:20 +0930 Subject: mmc: sdhci-of-aspeed: Turn down a phase correction warning The card timing and the bus frequency are not changed atomically with respect to calls to the set_clock() callback in the driver. The result is the driver sees a transient state where there's a mismatch between the two and thus the inputs to the phase correction calculation formula are garbage. Switch from dev_warn() to dev_dbg() to avoid noise in the normal case, though the change does make bad configurations less likely to be noticed.
