-DA7219 is an audio codec with advanced accessory detect features.
-
-======
-
-Required properties:
-- compatible : Should be "dlg,da7219"

-
-Optional properties:
-- interrupt-names : Name associated with interrupt line. Should be "wakeup" if
- interrupt is to be used to wake system, otherwise "irq" should be used.

-
-- #clock-cells : Should be set to '<1>', two clock sources provided;
-- clock-output-names : Names given for DAI clock outputs (WCLK & BCLK);

- ["diff", "se_p", "se_n"]
-
-Deprecated properties:
-- dlg,ldo-lvl : Required internal LDO voltage (mV) level for digital engine
- (LDO unavailable in production HW so property no longer required).
