Reading the PMIC values in Kernel Command Line

Hi all,

Please excuse if it is not a very intelligent question,

I am a beginner in linux kernel and application development,

I have a custom iMX6q board which has a MMPF10010 PMIC chip .

I am able to see the corresponding voltages when i boot the kernel

print_constraints: SW1A: 300 <--> 1875 mV at 1375 mV

print_constraints: SW1B: 300 <--> 1875 mV at 300 mV

print_constraints: SW1C: 300 <--> 1875 mV at 1375 mV

print_constraints: SW2: 800 <--> 3950 mV at 3300 mV

print_constraints: SW3A: 400 <--> 1975 mV at 1500 mV

print_constraints: SW3B: 400 <--> 1975 mV at 1500 mV

print_constraints: SW4: 800 <--> 3950 mV at 3150 mV

print_constraints: SWBST: 5000 <--> 5150 mV at 5000 mV

print_constraints: VSNVS: 1200 <--> 3000 mV at 1800 mV

print_constraints: VREFDDR: at 750 mV

print_constraints: VGEN1: 800 <--> 1550 mV at 1500 mV

print_constraints: VGEN2: 800 <--> 1550 mV at 1500 mV

print_constraints: VGEN3: 1800 <--> 3300 mV at 2500 mV

print_constraints: VGEN4: 1800 <--> 3300 mV at 1800 mV

print_constraints: VGEN5: 1800 <--> 3300 mV at 2800 mV

print_constraints: VGEN6: 1800 <--> 3300 mV at 3300 mV

but i am not able to figure out how i can print these values after my processor is booted in the kernel command line.

Is there any command using which i can do this?

regards,

nishad
