Subject: [PATCH 0/4] stratix10: Add Interrupt support for asynchronous
 communication with SDM

This patch-set adds support for interrupt from
Secure Device Manager(SDM) to Stratix10 SoC for
asynchronous communication.

Following things are added in this patch-set:
- Add support for interrupt from SDM to Stratix10 SoC.
- Add documentation for SDM interrupt in Stratix10 SoC.
- Enable SDM interrupt in Stratix10 SoC.
- Enable SDM interrupt in Agilex SoC.

These patches were originally submitted within a
different patch set, but were requested to be
separated into their own series.
