Subject: [RFC PATCH 02/10] dt-bindings: phy: rockchip: naneng-combphy: add rockchip,sgmii-mac-sel property
Date: Wed, 15 Jul 2026 03:08:30 +0800	[thread overview]
Message-ID: <20260714191341.690906-3-coiaprant@gmail.com> (raw)
In-Reply-To: <20260714191341.690906-1-coiaprant@gmail.com>

On RK3568, the SGMII interface can be routed to either GMAC0 or
GMAC1 via the pipe_sgmii_mac_sel bit in the pipe GRF registers.

Add the optional "rockchip,sgmii-mac-sel" property to allow the
device tree to select which GMAC controller is used for SGMII.

The property takes a value of 0 (GMAC0) or 1 (GMAC1), with 0 being
the default.

This is necessary for boards such as the Ariaboard Photonicat, where
the SGMII interface is connected to GMAC0 and needs to be explicitly
configured.
