Subject: [PATCH] arm64: dts: imx8m: Disable job ring 0 nodes
Date: Wed,  8 Jun 2022 14:02:23 -0300	[thread overview]
Message-ID: <20220608170223.1536594-1-festevam@denx.de> (raw)

Now that the JR0 reservation is done in both upstream (v2.7) and
downstream (NXP lf_v2.4) TF-A versions, the kernel fails to initialize
the job ring 0:

 # dmesg | grep jr
caam_jr 30901000.jr: failed to flush job ring 0
caam_jr: probe of 30901000.jr failed with error -5

Disable the sec_jr0 nodes by default to avoid the caam_jr probe error.
