Subject: [PATCH 1/2] ARM: dts: Drop duplicate sha2md5_fck to fix clk_disable race
Date: Mon, 8 Mar 2021 13:56:30 +0200 [thread overview]
Message-ID: <20210308115631.44270-2-tony@atomide.com> (raw)
In-Reply-To: <20210308115631.44270-1-tony@atomide.com>
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".
