Subject: [Qemu-devel] [PATCH v3 08/12] hw/devices: Move TI touchscreen declarations into a new header
Date: Fri, 12 Apr 2019 18:54:12 +0200	[thread overview]
Message-ID: <20190412165416.7977-9-philmd@redhat.com> (raw)
In-Reply-To: <20190412165416.7977-1-philmd@redhat.com>

Since uWireSlave is only used in this new header, there is no
need to expose it via "qemu/typedefs.h".
