I have pretty much the same config options: CONFIG_RTC_LIB=y CONFIG_RTC_CLASS=y CONFIG_RTC_HCTOSYS=y CONFIG_RTC_HCTOSYS_DEVICE="rtc0" CONFIG_RTC_SYSTOHC=y CONFIG_RTC_SYSTOHC_DEVICE="rtc0" CONFIG_RTC_INTF_SYSFS=y CONFIG_RTC_INTF_PROC=y CONFIG_RTC_INTF_DEV=y CONFIG_RTC_I2C_AND_SPI=y CONFIG_RTC_DRV_GENERIC=y The only difference seems to be that I don't have CONFIG_RTC_INTF_DEV_UIE_EMUL=y Helge > > CONFIG_RTC_LIB=y > CONFIG_RTC_CLASS=y > CONFIG_RTC_HCTOSYS=y > CONFIG_RTC_HCTOSYS_DEVICE="rtc0" > CONFIG_RTC_SYSTOHC=y > CONFIG_RTC_SYSTOHC_DEVICE="rtc0" > # CONFIG_RTC_DEBUG is not set > > # > # RTC interfaces > # > CONFIG_RTC_INTF_SYSFS=y > CONFIG_RTC_INTF_PROC=y > CONFIG_RTC_INTF_DEV=y > CONFIG_RTC_INTF_DEV_UIE_EMUL=y > # CONFIG_RTC_DRV_TEST is not set > # > # I2C RTC drivers > # > > # > # SPI RTC drivers > # > > # > # SPI and I2C RTC drivers > # > > # > # Platform RTC drivers > # > # CONFIG_RTC_DRV_DS1286 is not set > # CONFIG_RTC_DRV_DS1511 is not set > # CONFIG_RTC_DRV_DS1553 is not set > # CONFIG_RTC_DRV_DS1685_FAMILY is not set > # CONFIG_RTC_DRV_DS1742 is not set > # CONFIG_RTC_DRV_DS2404 is not set > # CONFIG_RTC_DRV_STK17TA8 is not set > # CONFIG_RTC_DRV_M48T86 is not set > # CONFIG_RTC_DRV_M48T35 is not set > # CONFIG_RTC_DRV_M48T59 is not set > # CONFIG_RTC_DRV_MSM6242 is not set > # CONFIG_RTC_DRV_BQ4802 is not set > # CONFIG_RTC_DRV_RP5C01 is not set > # CONFIG_RTC_DRV_V3020 is not set > > # > # on-CPU RTC drivers > # > CONFIG_RTC_DRV_GENERIC=y > > # > # HID Sensor RTC drivers -- To unsubscribe from this list: send the line "unsubscribe linux-parisc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
