These are all a bit odd. The register has a given size so they ought to
be u32 or u64 etc as appropriate for the register in question, ditto the
cache in the structure.

+	for (i = 0; i < MAX_EPS_CHANNELS; i++) {
+		offset = i * DWC_EP_REG_OFFSET;
+
+		dev_if->in_ep_regs[i] = (ulong)(reg_base +
+					       DWC_DEV_IN_EP_REG_OFFSET +
+					       offset);

And again some of the casting seems odd. If these are bus addresses they
should be typed as such.

+static inline u32 dwc_reg_read(ulong reg , u32 offset)
+{
+
+#ifdef CONFIG_DWC_OTG_REG_LE
+	return in_le32((void __iomem *)(reg + offset));
+#else
+	return in_be32((void __iomem *)(reg + offset));

All this casting is a symptom of the same typing problems. They would all
go away if the types were right in the first place.

+	u32 global_regs = (u32) core_if->core_global_regs;

And again we keep finding these casts caused by wrong types
