charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: "Linux-rockchip" Errors-To: linux-rockchip-bounces+linux-rockchip=archiver.kernel.org@lists.infradead.org On RK3568, the SGMII interface can be routed to either GMAC0 or GMAC1 via the GRF register pipe_sgmii_mac_sel. Add support for this selection by introducing the "rockchip,sgmii-mac-sel" DT property. >From the RK3568 TRM (Part1, Page 229), the PIPE_GRF_XPCS_CON0 bit 1 (pipe_sgmii_mac_sel) is defined as: 0: SGMII routed to GMAC0 1: SGMII routed to GMAC1 The hardware reset value is 1 (GMAC1). If the property is set to 0, the driver routes SGMII to GMAC0; if set to 1 (or omitted), it remains at GMAC1. This is necessary for boards such as the Ariaboard Photonicat, which uses the SGMII interface connected to GMAC0. Out-of-range values are rejected by dtschema, so the driver does not duplicate the range check.
