This patch looks good to me, but I am wondering, since we tend to use
device tree method to match driver, do we still need support platform
device ID ?

I'm not familiar with neither this IP block nor the SoC so it is up to
you. I just noticed this issue when reviewing a regulator driver for a
similar PMIC posted by someone from mediatek.

I thought platform device was needed since the driver has a MODULE_ALIAS()
but please let me know what you prefer and I can re-spin the patch and
just remove the MODULE_ALIAS() if that makes more sense for this platform.
  

I agree. We can alway add a MODULE_DEVICE_TABLE() if we get multiple
users of this driver on architectures that don't use devicetree yet.

Sure. Thanks the patch to add expandability to this driver.
