Add RTC DT entries in da850 dts file.
Signed-off-by: Mrugesh Katepallewar <mrugesh.mk@ti.com>
---
Applies on top of v3.8-rc4 of linus tree.
Tested on da850-evm device.
Test Procedure:
date [YYYY.]MM.DD-hh:mm[:ss]
hwclock -w
reset board and check system time.

Why two interrupts of the same number? If there is only one interrupt
line then only one should be specified, no?
Thanks,

We are using common OMAP RTC driver for da850 and other ti SoC's (e.g.am33xx). I have seen in am33xx.dtsi rtc timer
and alarm interrupts are different. So, two interrupt numbers are expected from RTC DT node.

I did not mention this last time, but this should be:
rtc0: rtc at 1c23000 {
to be consistent with rest of the file.

Okay. Looking at the OMAP-L138 TRM, I see that the IP on that SoC
supports both alarm and timer events and both arrive on the same
interrupt number (as opposed to am335x where they supposedly arrive on
different interrupt lines). What you have looks fine to me considering
this.
Also, the interrupt-parent setting needs to be removed. See the patch
Prabhakar just submitted.
Thanks,
Sekhar
