Subject: [PATCH v3 4/5] PCI: j721e: Add PCIe support for AM64
Date: Wed, 11 Aug 2021 18:03:35 +0530 [thread overview]
Message-ID: <20210811123336.31357-5-kishon@ti.com> (raw)
In-Reply-To: <20210811123336.31357-1-kishon@ti.com>
AM64 has the same PCIe IP as in J7200 with certain erratas not
applicable (quirk_detect_quiet_flag). Add support for "ti,am64-pcie-host"
compatible and "ti,am64-pcie-ep" compatible that is specific to AM64.
