Subject: [PATCH 0/3] Add alarm operation to the rtc-optee driver
Date: Tue, 15 Jul 2025 16:07:12 +0200 [thread overview]
Message-ID: <20250715-upstream-optee-rtc-v1-0-e0fdf8aae545@foss.st.com> (raw)
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.
