Subject: [PATCH AUTOSEL 5.12 51/80] mmc: sdhci-of-aspeed: Turn down a phase correction warning
Date: Sun, 4 Jul 2021 19:05:47 -0400 [thread overview]
Message-ID: <20210704230616.1489200-51-sashal@kernel.org> (raw)
In-Reply-To: <20210704230616.1489200-1-sashal@kernel.org>
From: Andrew Jeffery <andrew@aj.id.au>
[ Upstream commit a7ab186f60785850b5af1be183867000485ad491 ]
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.
