Subject: [PATCH AUTOSEL 5.11 06/51] ARM: dts: Drop duplicate sha2md5_fck to fix clk_disable race
Date: Mon, 12 Apr 2021 12:22:11 -0400
Message-ID: <20210412162256.313524-6-sashal@kernel.org> (raw)
In-Reply-To: <20210412162256.313524-1-sashal@kernel.org>

From: Tony Lindgren <tony@atomide.com>

[ Upstream commit 140a776833957539c84301dbdb4c3013876de118 ]

We have a duplicate legacy clock defined for sha2md5_fck that can
sometimes race with clk_disable() with the dts configured clock
for OMAP4_SHA2MD5_CLKCTRL when unused clocks are disabled during
boot causing an "Unhandled fault: imprecise external abort".
