rtc-opal driver provides support for rtc alarms via timed-power-on(tpo). However some Power platforms like BML use a fake rtc clock and don't support tpo. Such platforms are indicated by the missing 'has-tpo' property in the device tree. Current implementation however enables callback for rtc_class_ops.read/set alarm irrespective of the tpo support from the platform. This results in a failed opal call when kernel tries to read an existing alarms via opal_get_tpo_time during rtc device registration. This patch fixes this issue by setting opal_rtc_ops.read/set_alarm callback pointers only when tpo is supported. Acked-by:
