From mboxrd@z Thu Jan 1 00:00:00 1970 From: ulf.hansson@linaro.org (Ulf Hansson) Date: Wed, 7 Jun 2017 11:08:20 +0200 Subject: [PATCH 1/3] dt-bindings: net: Add binding for the external clock for TI WiLink In-Reply-To: <1496826502-1339-1-git-send-email-ulf.hansson@linaro.org> References: <1496826502-1339-1-git-send-email-ulf.hansson@linaro.org> Message-ID: <1496826502-1339-2-git-send-email-ulf.hansson@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The external clock is provided to the TI WiLink combo chip and it's needed for any of the transport interfaces. However let's make it optional to avoid breaking existing platforms that yet doesn't specify the clock.
