The IPQ5424 SoC has both USB2.0 and USB3.0 controllers. The USB3.0
can connect to either of USB2.0 or USB3.0 phy and operate in the
respective mode.

Shouldn't this be 19.2MHz ?

same comment as above, isn't this supposed to be 19.2MHz ?

DP/ DM interrupts ?

+				snps,dis_u2_susphy_quirk;
+				snps,dis_u3_susphy_quirk;

Disable u1/u2 entry as well please.
