What about having an allwinner,sun8i-h3-bus-reset, and adding it to the list of compatibles to initialise earlier in drivers/reset/reset-sunxi.c? Of course, it would cover the other reset controllers that you have below. > + apb1_rst: reset@01c202d0 { > + #reset-cells =3D <1>; > + compatible =3D "allwinner,sun6i-a31-clock-reset"; > + reg =3D <0x01c202d0 0x4>; > + }; > + > + apb2_rst: reset@01c202d8 { > + #reset-cells =3D <1>; > + compatible =3D "allwinner,sun6i-a31-clock-reset"; > + reg =3D <0x01c202d8 0x4>; > + }; > + > + timer@01c20c00 { > + compatible =3D "allwinner,sun4i-a10-timer"; > + reg =3D <0x01c20c00 0xa0>; > + interrupts =3D , > + ; > + clocks =3D <&osc24M>; > + }; > + > + wdt0: watchdog@01c20ca0 { > + compatible =3D "allwinner,sun6i-a31-wdt"; > + reg =3D <0x01c20ca0 0x20>; > + interrupts =3D ; > + }; > + > + uart0: serial@01c28000 { > + compatible =3D "snps,dw-apb-uart"; > + reg =3D <0x01c28000 0x400>; > + interrupts =3D ; > + reg-shift =3D <2>; > + reg-io-width =3D <4>; > + clocks =3D <&apb2_gates 16>; > + resets =3D <&apb2_rst 16>; > + dmas =3D <&dma 6>, <&dma 6>; > + dma-names =3D "rx", "tx"; > + status =3D "disabled"; > + }; > + > + uart1: serial@01c28400 { > + compatible =3D "snps,dw-apb-uart"; > + reg =3D <0x01c28400 0x400>; > + interrupts =3D ; > + reg-shift =3D <2>; > + reg-io-width =3D <4>; > + clocks =3D <&apb2_gates 17>; > + resets =3D <&apb2_rst 17>; > + dmas =3D <&dma 7>, <&dma 7>; > + dma-names =3D "rx", "tx"; > + status =3D "disabled"; > + }; > + > + uart2: serial@01c28800 { > + compatible =3D "snps,dw-apb-uart"; > + reg =3D <0x01c28800 0x400>; > + interrupts =3D ; > + reg-shift =3D <2>; > + reg-io-width =3D <4>; > + clocks =3D <&apb2_gates 18>; > + resets =3D <&apb2_rst 18>; > + dmas =3D <&dma 8>, <&dma 8>; > + dma-names =3D "rx", "tx"; > + status =3D "disabled"; > + }; > + > + uart3: serial@01c28c00 { > + compatible =3D "snps,dw-apb-uart"; > + reg =3D <0x01c28c00 0x400>; > + interrupts =3D ; > + reg-shift =3D <2>; > + reg-io-width =3D <4>; > + clocks =3D <&apb2_gates 19>; > + resets =3D <&apb2_rst 19>; > + dmas =3D <&dma 9>, <&dma 9>; > + dma-names =3D "rx", "tx"; > + status =3D "disabled"; > + }; > + > + gic: interrupt-controller@01c81000 { > + compatible =3D "arm,cortex-a7-gic", "arm,cortex-a15-gic"; > + reg =3D <0x01c81000 0x1000>, > + <0x01c82000 0x1000>, > + <0x01c84000 0x2000>, > + <0x01c86000 0x2000>; > + interrupt-controller; > + #interrupt-cells =3D <3>; > + interrupts =3D ; > + }; > + > + rtc: rtc@01f00000 { > + compatible =3D "allwinner,sun6i-a31-rtc"; > + reg =3D <0x01f00000 0x54>; > + interrupts =3D , > + ; > + }; > + }; > +}; > --=20 > 2.3.7 >=20 Have you tested the architected timers?
