Laxman Dewangan - March 21, 2013, 2:32 p.m.
Add of_device_id table for Palma RTC to be enable the
driver from DT file.

The driver can be registered from DT file as:
	palmas: tps65913@58 {
		:::::::::::
		palmas_rtc {
			compatible = "ti,palmas-rtc";
			interrupt-parent = <&palmas>;
			interrupts = <8 0>;
		};
	};
