Subject: [PATCH v1] Revert "dmaengine: stm32-mdma: Add a check on read_u32_array"
Date: Mon, 25 Mar 2019 15:46:27 +0100 [thread overview]
Message-ID: <1553525187-13533-1-git-send-email-pierre-yves.mordret@st.com> (raw)
This reverts commit 906b40b246b0acb54c4dc97e815cf734761c9820.
As stated by bindings "st,ahb-addr-masks" is optional.
The statement inserted by this commit makes this property
mandatory and prevents MDMA to be probed in case property not present.
