Hi,

I have a customised imx6sl board with TI-PMIC TPS65910. I am not able to register tps65910 rtc driver. I am getting the following error.

tps65910-rtc tps65910-rtc: IRQ 6 is not free.
tps65910-rtc: probe of tps65910-rtc failed with error -22

    Hi Vip,

    It looks like IRQ6 is already being utilized by another driver, does it support a shared IRQ?

    Hi,

    Yes, from the logs it is clear that the irq 6 is already being used by some other driver. But when I am checking /proc/interrupts dir. there is no IRQ with number 6.

    This is the output of /proc/interrupts

    Hi Chase Maupin,

    Interrupt pin of the PMIC TPS65910 was not configured in dts file. So, I just configured the Interrupt pin in dts file and it solve the issue.
