Subject: [PATCH 0/3] Add alarm operation to the rtc-optee driver

The optee-rtc driver is used to query the rtc handled by OP-TEE OS
through PTA (Pseudo Trusted Application) call.
This serie fixes memory concerns and add alarm operations for the
rtc-optee driver as the RTC PTA now support them [1].

For the alarm notification, the OP-TEE OS secure world will be
able to inform the kernel when a secured alarm will occured
through a notification sent to a kernel thread waiting in OP-TEE OS.
