[PATCH v2 net-next 0/3] net: stmmac: RK3566

[Ezequiel Garcia]

Now that RK3568 SoC devicetree upstreaming is happening [1],
here's another round for the RK3566 dwmac. There wasn't any clear
consensus on how to implement the two interfaces present
on RK3568, so I decided to drop that and just submit RK3566 for now.

This has been tested on a Pine64 RK3566 Quartz64 Model B board,
DHCP and iperf are looking good.

For all the people testing, here's Quartz 64 Model B device tree
snippet:

        gmac1: ethernet at fe010000 {
                compatible = "rockchip,rk3566-gmac", "snps,dwmac-4.20a";
                reg = <0x0 0xfe010000 0x0 0x10000>;
                interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>,
                             <GIC_SPI 29 IRQ_TYPE_LEVEL_HIGH>;
                interrupt-names = "macirq", "eth_wake_irq";
                rockchip,grf = <&grf>;
                clocks = <&cru SCLK_GMAC1>, <&cru SCLK_GMAC1_RX_TX>,
                         <&cru SCLK_GMAC1_RX_TX>, <&cru CLK_MAC1_REFOUT>,
                         <&cru ACLK_GMAC1>, <&cru PCLK_GMAC1>,
                         <&cru SCLK_GMAC1_RX_TX>, <&cru CLK_GMAC1_PTP_REF>;
                clock-names = "stmmaceth", "mac_clk_rx",
                              "mac_clk_tx", "clk_mac_refout",
                              "aclk_mac", "pclk_mac",
                              "clk_mac_speed", "ptp_ref";
                resets = <&cru SRST_A_GMAC1>;
                reset-names = "stmmaceth";

                snps,mixed-burst;
                snps,tso;

                snps,axi-config = <&gmac1_stmmac_axi_setup>;
                snps,mtl-rx-config = <&gmac1_mtl_rx_setup>;
                snps,mtl-tx-config = <&gmac1_mtl_tx_setup>;
                status = "disabled";

                mdio1: mdio {
                        compatible = "snps,dwmac-mdio";
                        #address-cells = <0x1>;
                        #size-cells = <0x0>;
                };

                gmac1_stmmac_axi_setup: stmmac-axi-config {
                        snps,wr_osr_lmt = <4>;
                        snps,rd_osr_lmt = <8>;
                        snps,blen = <0 0 0 0 16 8 4>;
                };

                gmac1_mtl_rx_setup: rx-queues-config {
                        snps,rx-queues-to-use = <1>;
                        queue0 {};
                };

                gmac1_mtl_tx_setup: tx-queues-config {
                        snps,tx-queues-to-use = <1>;
                        queue0 {};
                };
        };

While here, I'm adding a small patch from David Wu, for some
sanity checks for dwmac-rockchip-specific non-NULL ops.

Thanks!
