Subject: [PATCH 5/9] dt-bindings: mmc: mmci: add delay block base register for sdmmc
Date: Fri, 10 Jan 2020 14:48:19 +0100	[thread overview]
Message-ID: <20200110134823.14882-6-ludovic.barre@st.com> (raw)
In-Reply-To: <20200110134823.14882-1-ludovic.barre@st.com>

To support the sdr104 mode, the sdmmc variant has a
hardware delay block to manage the clock phase when sampling
data received by the card.

This patch adds a second base register (optional) for
sdmmc delay block.
