stop b2g and start b2g can workaround, but I wonder if this is the issue that gecko is reverted to 4.2.2.
Blocks: flatfish

    
    

    
  
1. kernel CPU_FREQ_DEFAULT_GOV_FANTASYS is disabled and rebuild all related kernel modules.
2. adding axp22-supplyer.kl for power button
3. Fixing HMI error
suspend and resume can work now.

    
    

    
  
kernel panic issue:
1. kernel CPU_FREQ_DEFAULT_GOV_PERFORMANCE is enable by default for faster bootup
2. when boot as Android, scaling_governor will be set to fantasys.
     this seems set by DynamicPManagerService.java this framework service.
   but when boot as FxOS, scaling_governor still is performance, system will kernel panic when suspend.
     and there is no DynamicPManagerService.java in FxOS source code.
3. we can add "write /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor fantasys" to init.flstfish.rc
    instead of rebuild kernel, and we still need fantasys governor mode.

blank screen after resume:
after we fix kernel panic as above, LCD will be blank after resume. just wondering if there have another framework service take care of resume.

    
    

    
  
it has been resolved by enabling fantasy cpufreq in init.flatfish.rc
    write /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor fantasys
