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
