Subject: [PATCH v3 06/10] dt-bindings: mtd: update STM32 FMC2 NAND controller documentation
Date: Tue, 5 May 2020 19:11:04 +0200	[thread overview]
Message-ID: <1588698668-25288-7-git-send-email-christophe.kerello@st.com> (raw)
In-Reply-To: <1588698668-25288-1-git-send-email-christophe.kerello@st.com>

These bindings can be used on SOCs where the FMC2 NAND controller is
in standalone. In case that the FMC2 embeds 2 controllers (an external
bus controller and a raw NAND controller), the register base and the
clock will be defined in the parent node. It is the reason why the
register base address and the clock are now optional.
