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 v5:
- use read_cpuid_part() but not read_cpuid_part_number()
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
- modify the author info for patches
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
