I'm not aware of this being submitted as part of another series, that's probably because commit f08d1c085638 ("phy: phy-rockchip-samsung-hdptx: Don't use dt aliases to determine phy-id"), which actually changed the approach of mapping the PHY IDs, has been applied fairly recently.

Despite the compatible already being listed in the bindings, the PHY driver never gained explicit support for it. This is especially a problem because the explicitly listed PHY addresses need to be specified for each SoC. To solve this, add the compatible, and a PHY config, with the address gleaned from rk3576.dtsi.
