I have a new device I need to add to the TI LMU code LM36274.
This will use the MFD ti-lmu code and I will need to create the backlight and regulator drivers.

I need to know how to proceed.  I can base the work off of the LM3532 patchset or use what is in mainline
or base it off this patchset.  The LM36274 would use the ti-lmu-led-common code for brightness setting but the
ramping times are different.

Please let me know how to proceed.
