   4 Subject: [PATCH 215/752] ASoC: davinci-mcasp: Interrupts property to optional
   5  and add interrupt-names
   6
   7 Makes interrupts property optional as the interrupts are not currently
   8 used by the driver and adds interrupt-names property to name listed
   9 interrupts. Currently know interrupt names are "tx" and "rx".
