In order to support different types of irq design,
we decide to add separate irq drivers for different
design and keep mt6397 mfd core simple and reusable
to all generations of PMICs so far.
Why have you cut these lines so short?

In all cases:

 s/irq/IRQ/
 s/mfd/MFD
 s/mt6397/MT6397/
quoted hunk ↗ jump to hunk

I will ignore these unrelated changes!

CID_CODE is a bit cryptic.

Why not use *_CHIP_ID instead?

[...]
+static const struct chip_data mt6323_core = {
+	.cid_addr = MT6323_CID,
+};
Does the chip ID address change from device to device?

If not, you can get rid of all of this hoop jumping.
