Spreadtrum is a rapid growing chip vendor providing smart phone total solutions.
Shark64 is nominated as a SoC infrastructure that supports 4G/3G/2G standards based on ARMv8 multiple core architecture.
This patchset adds shark64 supports in arm64 device tree and implements the basic earlycon serial driver.

Usually the SoC goes into a .dtsi file that can then be reused for multiple boards (.dts). Even if you only have one board for now, this distinction makes sense. You can use status = "disabled"; to prepare nodes in the .dtsi and then override the ones used via status = "okay"; in the .dts file. UARTs are a typical example where you will see this pattern used. > + compatible = "sprd,shark64"; > + interrupt-parent = <&gic>; > + #address-cells = <2>; > + #size-cells = <2>; > + > + chosen { > + bootargs = "earlycon=serial_sprd,0x70000000"; > + }; Some spaces snuck into this line. ;) Cheers, Andreas > + > + cpus { > + #address-cells = <2>; > + #size-cells = <0>; > + > + cpu@0 { > + device_type = "cpu"; > + compatible = "arm,armv8"; > + reg = <0x0 0x0>; > + enable-method = "spin-table"; > + cpu-release-addr = <0x0 0x8000fff8>; > + }; > + cpu@1 { > + device_type = "cpu"; > + compatible = "arm,armv8"; > + reg = <0x0 0x1>; > + enable-method = "spin-table"; > + cpu-release-addr = <0x0 0x8000fff8>; > + }; > + cpu@2 { > + device_type = "cpu"; > + compatible = "arm,armv8"; > + reg = <0x0 0x2>; > + enable-method = "spin-table"; > + cpu-release-addr = <0x0 0x8000fff8>; > + }; > + cpu@3 { > + device_type = "cpu"; > + compatible = "arm,armv8"; > + reg = <0x0 0x3>; > + enable-method = "spin-table"; > + cpu-release-addr = <0x0 0x8000fff8>; > + }; > + }; > + > + memory@80000000 { > + device_type = "memory"; > + reg = <0 0x80000000 0 0x20000000>; > + }; > + > + aliases { > + serial0 = &uart0; > + serial1 = &uart1; > + }; > + > + gic: interrupt-controller@12001000 { > + compatible = "arm,cortex-a15-gic", "arm,cortex-a9-gic"; > + #interrupt-cells = <3>; > + #address-cells = <0>; > + interrupt-controller; > + reg = <0 0x12001000 0 0x1000>, > + <0 0x12002000 0 0x1000>; > + }; > + > + intc:interrupt-controller@71400000 { > + compatible = "sprd,intc"; > + #interrupt-cells = <0>; > + interrupt-controller; > + reg = <0 0x71400000 0 0x1000>, > + <0 0x71500000 0 0x1000>, > + <0 0x71600000 0 0x1000>, > + <0 0x71700000 0 0x1000>; > + }; > + > + timer { > + compatible = "arm,armv8-timer"; > + interrupts = <1 13 0xff01>, > + <1 14 0xff01>, > + <1 11 0xff01>, > + <1 10 0xff01>; > + clock-frequency = <26000000>; > + }; > + > + uart0: uart@70000000 { > + compatible = "sprd,serial"; > + reg = <0 0x70000000 0 0x100>; > + interrupts = <0 2 0xf04>; > + }; > + > + uart1: uart@70100000 { > + compatible = "sprd,serial"; > + reg = <0 0x70100000 0 0x100>; > + interrupts = <0 3 0xf04>; > + }; > +}; -- SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer; HRB 16746 AG Nürnberg -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html ^ permalink raw reply [flat|nested] 13+ messages in thread

Also, it looks to me as if the ordering is alphabetical, so SHARK should probably go somewhere before VEXPRESS, not after XGENE.
