Subject: [PATCH v2 1/1] arm64: dts: cn913x: add device trees for COM Express boards
Date:   Wed, 25 Oct 2023 10:31:50 +0300
Message-ID: <20231025073150.2826130-2-enachman@marvell.com>

From: Elad Nachman <enachman@marvell.com>

Add support for CN9130 and CN9131 COM Express Type 7 CPU
module boards (SOM boards) by Marvell.
Define these COM Express CPU modules / SOMs as dtsi, and
provide a dts file for a carrier board (Marvell AC5X RD
COM Express type 7 carrier board).
This Carrier board only utilizes the PCIe link, hence no
special device / driver support is provided by this dts file.

These boards differ from the existing CN913x DB boards by the type
of ethernet connection (RGMII), the type of voltage regulators
(not i2c expander based) and the USB phy (not UTMI based).
CN9131 COM Express board is basically CN9130 COM Express board
with an additional CP115 I/O co-processor, which in this case
provides an additional USB host controller on the board.
