sorry for the delayed reply from my end.
Right now I am under the constraint where I cannot share the datasheet. But yes, the datasheet is going be out very soon. I shall update u about the same
Can the pmbus driver be used to set output voltage from another driver in the kernel space itself. what I understood about the pmbus driver is that it is meant for monitoring and controlling. at my end if the monitoring is being done by another entity(voltage regulator) and the controlling only needs to be done by the PMIC then how do I go about? say I just want to use VOUT_TRIM command.
is there any sample implementation where I can see how the pmbus api's are called ?

Hi Vivek,
The lm-sensors mailing list would be the best place to ask, but this will do.

I am copying the list.
The driver supports BMR45x, which are the same type of controller. So, yes, the driver

should work. Just give it a try. If the generic driver doesn't work, you (or I)
can write a little front-end driver to tell the PMBus core driver which registers are
supported. Worst case the driver may need some patches, but that is unlikely.
Do you have a datasheet ?
Thanks,
