Subject: [PATCH v6 11/14] ARM: dts: Add PCIe support for Airoha EN7523
Date: Fri, 3 Dec 2021 12:33:28 +0100 [thread overview]
Message-ID: <20211203113331.20510-12-nbd@nbd.name> (raw)
In-Reply-To: <20211203113331.20510-1-nbd@nbd.name>
This uses the MediaTek MT7622 PCIe driver, since the PCIe IP block is nearly
identical to the one in MT7622
Signed-off-by: Felix Fietkau <nbd@nbd.name>
