Subject: [PATCH] PCI: imx6: Limit DBI register length for imx6qp pcie
Date: Thu, 18 Feb 2021 13:09:40 +0800 [thread overview]
Message-ID: <1613624980-29382-1-git-send-email-hongxing.zhu@nxp.com> (raw)
Refer to commit 075af61c19cd ("PCI: imx6: Limit DBI register length"),
i.MX6QP PCIe has the similar issue.
Define the length of the DBI registers and limit config space to its
length for i.MX6QP PCIe too.
