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