Subject: [PATCH v2 2/4] dt-bindings: arm: scmi property mboxes is not mandatory
Date: Fri, 21 May 2021 15:40:52 +0200	[thread overview]

In-Reply-To: <20210521134055.24271-1-etienne.carriere@linaro.org>

Since "arm,scmi-smc" compatible support, mboxes property is not mandated.
This change fixes the DT bindings description accordingly.
