Nothing improved. You never replied to comments and then replaced one
redundant word into other redundant word.

Respond to review or implement it fully, not partially.

Or add COMPLETE bindings, not partial ones. See writing bindings doc.
OK, right so the DT binding should describe the overall PMIC device,
even though the driver needs to support the RTC.
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.

This is not a driver patch. This is patch for hardware. Sending
incomplete pieces of a device, without complete picture is really not
the right way. Knowing this is part of PMIC this should be rejected, but
how can we decide on that if contributor never tells us this is a part
of PMIC?
Yes I understand that this is not a driver patch and must describe the 
hardware. It is a simple misunderstanding because it was rejected as an 
MFD, but we should not have then made the DT look like only a RTC 
device. This is a mistake on our side and we will fix.
I acknowledge, will improve bindings by describing VRS-10 hardware for 
clear understanding.
