Hi Johan,

  I wanted to add them when wakeup-source is enabled but since you 
mentioned that these must be added now and driver support can be added 
later, I will make a patch separately for this in v9.

Hi Krzysztof,

  Can I use the following notation for the new interrupts ?

dp_hs_port2_irq
dm_hs_port2_irq
dp_hs_port3_irq
dm_hs_port3_irq
dp_hs_port4_irq
dm_hs_port4_irq


That way the interrupt names for first port will be same as ones for 
single port.

Wanted to clarify this before I make a formal patch.

Regards,
Krishna,
