VRS-10 is the device name. VRS-10 has an I2C interface and implements a
power sequencer, RTC , 32kHZ clock output. From software perspective, we
are handling VRS-10 interrupts and providing RTC driver support. I will
add complete VRS-10 information in bindings.

I acknowledge, will improve bindings by describing VRS-10 hardware for
clear understanding.
