You don't have a .of_match table but according the DT bindings, the
compatible string "mediatek,mt6323-regulator" should be used so there
should be a OF match table or the vendor prefix of the compatible
string won't be used for matching (i.e: fallbacks to the driver .name
for match).

the driver is probed via drivers/mfd/mt6397-core.c and does not require
the OF match table. It loads fine just like the mt6397 driver.

That's fine but you shouldn't have the compatible string in your binding
document since it's not actually used or needed.

Hi,

correct me if i am wrong but if we remove the compatible string from the
binding document, then we will also have to remove it from the dts and
then the kernel won't be able to match the node to the driver and thus
the regulator phandle derefs will fail.
