The reset definitions would be clearer with declarations as the other
Allwinner SoCs and without driver hack:
soc {
compatible = "simple-bus";
#address-cells = <1>;
#size-cells = <1>;
ranges;
dma: dma-controller@01c02000 {
compatible = "allwinner,sun8i-h3-dma";
reg = <0x01c02000 0x1000>;
interrupts = <GIC_SPI 50 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&bus_gates 6>;
resets = <&rst_reg0 6>;
#dma-cells = <1>;
};
...
rst_reg0: reset@01c202c0 {
#reset-cells = <1>;
compatible = "allwinner,sun6i-a31-clock-reset";
reg = <0x01c202c0 0x04>;
};
...
rst_reg4: reset@01c202d8 {
#reset-cells = <1>;
compatible = "allwinner,sun6i-a31-clock-reset";
reg = <0x01c202d8 0x04>;
};
...
uart0: serial@01c28000 {
compatible = "snps,dw-apb-uart";
reg = <0x01c28000 0x400>;
interrupts = <GIC_SPI 0 IRQ_TYPE_LEVEL_HIGH>;
reg-shift = <2>;
reg-io-width = <4>;
clocks = <&bus_gates 112>;
resets = <&rst_reg4 16>;
dmas = <&dma 6>, <&dma 6>;
dma-names = "rx", "tx";
status = "disabled";
};
