I'm not sure if I get your perspective right & please correct me if I'm wrong,
I'm just trying to adjust the dt binding of max5970 because found
errors related to
regulator child node SW0/SW1.
Regulator driver expects to have regulators child nodes as SW0/1(upper case)
But dt binding expects it to be lower case.
Thus there is misalignment & due to which, when running CHECK_DTBS for my
mainboard DTS, I see some errors.

The current patch is to address the regulators child node name with driver.
