Enable TPS65910 RTC on AM335x in linux

Other Parts Discussed in Thread: TPS65910

Hello,

I'm working on a custom board. We put a supercap on the TPS65910 to enable RTC during power off.

I've modified the device tree to enable the supercap charger, this is working well.

Now I want to add the TPS65910-rtc driver on linux, but I got an error message during boot :

[    1.676581] tps65910-rtc tps65910-rtc: IRQ is not free.
[    1.682101] tps65910-rtc: probe of tps65910-rtc failed with error -22
[    1.928911] omap_rtc 44e3e000.rtc: setting system clock to 2015-03-09 17:16:49 UTC (1425921409)

Has somebody an idea ?

Best regards

Steve
