Subject: [PATCH net-next v2 14/14] arm64: dts: qcom: qcs6490-rb3gen2: enable TC9564 with a single QCA8081 phy
Date: Thu, 4 Jun 2026 20:00:21 -0500 [thread overview]
Message-ID: <20260605010022.968612-15-elder@riscstar.com> (raw)
In-Reply-To: <20260605010022.968612-1-elder@riscstar.com>
From: Daniel Thompson <daniel@riscstar•com>
The QCS6490 RB3Gen2 includes a Toshiba TC9564 (a.k.a. Qualcomm QPS615).
TC9564 is an twin Ethernet-AVB/TSN bridge with an integrated PCIe switch.
Downstream PCIe switch port 3 has an embedded PCIe endpoint, which
includes two functions. The GPIO controller embedded within the
TC9564 is accessed via memory-mapped I/O through the first PCIe
function's BAR4.
Both embedded PCIe functions have an attached Synopsys XGMAC, but
not all RB3gen2 builds include PHYs on both ports. All versions
include a TC9564 combined with a single QCA8081 attached to eMAC1.
Add properties to the existing PCI nodes to describe how the TC9564 and
QCA8081 are connected to each other (and to the host SoC).
