rk3288 is qual-core CPU Soc, we enable the smp in this patch. In version 3 we use regmap and pmu syscon for cpu power on/off. This should be work after Pankaj Dubey's patch applied: "syscon: Decouple syscon interface from platform devices" (https://lkml.org/lkml/2014/9/30/156) Changes in v4: - add rockchip,pmu property into cpus.txt - merge patch "fix up rk3288 smp cpu hotplug" into this patch - remove "rockchip,rk3288-pmu-sram" because we don't use it here - remove "[PATCH v3 2/6] ARM: dts: rockchip: use the same pmu node" Changes in v3: - add pmu regmap patches in version 3 - use one ops and secondary_starup for all rockchip SOCs - pick back the power domain operation for cpu hotplug - remove 'enable-method' from this patch - add compitable name "rockchip,rk3288-pmu-sram" for pmu-intmem Changes in v2: - use rk3288_boot_secondary instead ofsmp_boot_secondary - discards the power domain operation - handle the per cpu starup when actived by 'sev' - adjust the alignment Kever Yang (6): ARM: rockchip: convert to regmap and use pmu syscon if available ARM: rockchip: add option to access the pmu via a phandle in smp_operations ARM: dts: rockchip: add pmu references to cpus nodes ARM: rockchip: add basic smp support for rk3288 ARM: dts: rockchip: add intmem node for rk3288 smp support ARM: dts: rockchip: add reset for CPU nodes Documentation/devicetree/bindings/arm/cpus.txt | 9 + arch/arm/boot/dts/rk3288.dtsi | 18 ++ arch/arm/mach-rockchip/headsmp.S | 5 +- arch/arm/mach-rockchip/platsmp.c | 223 ++++++++++++++++++++----- 4 files changed, 211 insertions(+), 44 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
