Subject: [PATCH v2 4/6] PCI: j721e: Add PCIe support for AM64
Date: Tue, 3 Aug 2021 13:19:30 +0530	[thread overview]
Message-ID: <20210803074932.19820-5-kishon@ti.com> (raw)
In-Reply-To: <20210803074932.19820-1-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.
