Subject: [PATCH v2 2/4] dt-bindings: snps,dw-apb-ssi: Add optional clock domain information
Date:   Wed, 18 Sep 2019 09:04:34 +0100
Message-Id: <1568793876-9009-3-git-send-email-gareth.williams.jx@renesas.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Note in the bindings documentation that pclk should be renamed if a clock
domain is used to enable the optional bus clock.
