Subject: [PATCH 1/3] dt-bindings: edac: Add binding for L1/L2 error detection for Cortex A53/57
Date: Tue, 13 Oct 2020 14:50:31 +0200 [thread overview]
Message-ID: <20201013125033.4749-2-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20201013125033.4749-1-s.hauer@pengutronix.de>
The ARM Cortex-A53 and A57 CPUs support error detection for the L1/L2
caches. This patch adds a binding for the corresponding driver.
