Subject: [PATCH 2/4] dt-bindings: mmc: iproc-sdhci: Add clock-frequency support
Date: Mon, 22 Mar 2021 19:58:15 +0100 [thread overview]
Message-ID: <20210322185816.27582-3-nsaenz@kernel.org> (raw)
In-Reply-To: <20210322185816.27582-1-nsaenz@kernel.org>
Users might want to choose a different clock frequency than whatever the
bootloader provided at probe time. Add 'clock-frequency' bindings.
