Subject: [PATCH 0/2] selftest: rtc: Add rtc feature detection and rtc file check

1. In order to make rtctest more explicit and robust, we propose to use
RTC_PARAM_GET ioctl interface to check rtc alarm feature state before
running alarm related tests.

2. The rtctest requires the read permission on /dev/rtc0. The rtctest will
be skipped if the /dev/rtc0 is not readable.

Joseph Jang (2):
  selftest: rtc: Add to check rtc alarm status for alarm related test
  selftest: rtc: Check if could access /dev/rtc0 before testing
