For the record the serdes needs to toggle some muxes to work.

And the pon serdes is different compared to the other 3 serdes instances (usb-serdes, wifi1-serdes and wifi2-serdes).

These are the XSI MACs, no real driver needed. But during development it can be used for checking rx and tx counters.

	reg = <0x1fa60000 0x300>,	  //hsgmii ae
	      <0x1fa70000 0x300>,   //hsgmii pcie0

sgmii_p0 and sgmii_p1 and sgmii_pu are the serdes instances. The board I have is using sgmii_pu together with a phy.

I'm going to update this driver so I can test it, I'm going to migrate some things to the kernel so I can test it, I recently rewrote it to use regmap and now I'm going to update some things

I think the dts should be reordered like this:

eth_pcs: pcs@1fa09000 {
	compatible = "airoha,en7523-pcs-sgmii", "airoha,en7523-pcs-eth";
	reg =	<0x1fa81000 0x64>,
				<0x1fa81100 0x338>,
				<0x1fa81600 0xdc>,
				<0x1fa81a00 0x160>,
				<0x1fa81c00 0x3b0>;
	reg-names = "hsgmii_an",
		    "hsgmii_phya";
		    "hsgmii_rate_adp", 
		    "hsgmii_pcs",
		    "hsgmii_qphy_csr",

	resets = <&scu EN7523_XSI_PHY_RST>;
	reset-names = "phy";

	interrupts = <GIC_SPI 153 IRQ_TYPE_LEVEL_HIGH>;	// usb_hsgmii INT 137+16

	airoha,scu = <&scu>;
};
