Hi Alexandre,
Thank you for the review. See my answers below.

Thanks. I will fix this in v2.

Alarmtimer interface relies only on RTC with alarm support, but it also checks wake flags for some reason. As far as rtc-test driver do have alarm support, I expect that related drivers should use it.
Let me share some information about my use-case: Alarmtimer support is required for generic AOSP bluedroid library. To enable Bluetooth in Android on the devices that does not have hardware RTC, enabling rtc-test driver is a good option.
