While adding the USB support, it was found that the configuration
for regulator smps5 was incorrectly set. Upon cross verifying for
all the regulators, found that smps4, smps6 and smps8 are also
incorrectly configured. This patch fixes the same.
Nit: see Documentation/process/submitting-patches.rst, "This patch..."
Will update the commit message.
In particular -
- smps4 is 1.574V min and 2.04V max
- smps5 is 1.2V min and 1.4V max
- smps6 is 0.382V min and 1.12V max
Just for my understanding, will anything further constraint these values?
As far as i know, this is going to be final.
currently, usb device is not working without this min/max change.
Thanks
Komal
- smps8 is fixed at 0.752V
