Lee and Mark,

LM363X regulator driver supports LM3631 and LM3632.
LM3631 has 5 regulators. LM3632 provides 3 regulators.
One boost output and LDOs are used for the display module.
Boost voltage is configurable but always on.
Supported operations for LDOs are enabled/disabled and voltage change.

Two LDOs of LM3632 can be controlled by external pins.
Those are configured through the DT properties.

I'm creating the 3rd patch-set but this driver is found in linux-next 
tree. And Axel Lin has patched this driver. In my patch v3, modified 
part is DT properties for external enable pins. (Use '-gpios' instead of 
'-gpio')

So, I'd like to know which is better for you.
a) Create a patch based on linux-next tree (the above patch)
Or
b) Re-generate a patch based on linux-mfd tree

Best regards,
Milo
