Subject: [PATCH 1/3] hw/misc/mps2-scc: Add "QEMU interface" comment
Date: Mon, 12 Apr 2021 14:43:15 +0100 [thread overview]
Message-ID: <20210412134317.12501-2-peter.maydell@linaro.org> (raw)
In-Reply-To: <20210412134317.12501-1-peter.maydell@linaro.org>
The MPS2 SCC device doesn't have any documentation of its properties;
add a "QEMU interface" format comment describing them.
