MK908 v5 RK3188 CPU speed problem top speed 1200MHZ

[RRPRIME]

I have a MK908 v5.
I have tried the kernel from:

https://github.com/phjanderson/Linux3188

also:

https://github.com/omegamoon/Rockchip-GPL-Kernel

The best the cpu does is 1200MHZ the governor is interactive.
Config files were done via marvin + manual editing. Tried also https://github.com/phjanderson/rkpatchomatic but was not able to patch it.

as far as i can see the voltages+speed are defined in the board-rk3188-box.c and cpufreq.c in teh config all is ok:

CONFIG_RK_CPU_312=y
CONFIG_RK_CPU_312_VOLT=900
CONFIG_RK_CPU_504=y
CONFIG_RK_CPU_504_VOLT=925
CONFIG_RK_CPU_816=y
CONFIG_RK_CPU_816_VOLT=1000
CONFIG_RK_CPU_1008=y
CONFIG_RK_CPU_1008_VOLT=1075
CONFIG_RK_CPU_1200=y
CONFIG_RK_CPU_1200_VOLT=1150
CONFIG_RK_CPU_1416=y
CONFIG_RK_CPU_1416_VOLT=1250
CONFIG_RK_CPU_1608=y
CONFIG_RK_CPU_1608_VOLT=1350
CONFIG_RK_CPU_1704=y
CONFIG_RK_CPU_1704_VOLT=1375
CONFIG_RK_CPU_1800=y
CONFIG_RK_CPU_1800_VOLT=1375

also tied limiting the cpu to:
CONFIG_RK_CPU_1800=y
CONFIG_RK_CPU_1800_VOLT=1375
only but to no luck.

Also i suspect that the DDR freq are not ok.

The governors are not ok...i get crashes when trying to switch it.

/sys/devices/system/cpu/cpu(0-3)/cpufreq/cpuinfo_max_freq states 1800000
if I change hispeed_freq from
/sys/devices/system/cpu/cpufreq/interactive/
to 1800000
and go_hispeed_load to 1
so that if the load is higher the 1 it should go to 1800Mhz i get a crash, if i change ot to 1200mhz all is ok.
Any ideas ?

Update

Update:

I found that the repo was tainted.
I have built a kernel for T428 with cpu1800 it seems ok but..cpu goes from 312MHZ to 1800MHZ no intermediate freq. Governors are ok.

Built for the mk908 with cpu1800 it just hangs so i activated the serial console.
got a panic:
