Subject: [PATCH 3/4] MIPS: dts: eyeq5: add MSI controllers
Date: Wed, 28 Oct 2026 16:58:50 +0100 [thread overview]
Message-ID: <20261028-eyeq5_msi-v1-3-c464752fb55f@bootlin.com> (raw)
In-Reply-To: <20261028-eyeq5_msi-v1-0-c464752fb55f@bootlin.com>
Add the two EyeQ5 MSI controllers. They use reserved-memory regions as
their doorbell windows.
