Subject: [PATCH AUTOSEL 5.10 14/25] PCI: j721e: Add PCIe support for AM64
Date: Sat, 11 Sep 2021 09:13:01 -0400 [thread overview]
Message-ID: <20210911131312.285225-14-sashal@kernel.org> (raw)
In-Reply-To: <20210911131312.285225-1-sashal@kernel.org>
From: Kishon Vijay Abraham I <kishon@ti.com>
[ Upstream commit c8a375a8e15ac31293d7fda08008d6da8f5df3db ]
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.
