Subject: [PATCH v2 0/4] Basic Allwinner WDT emulation
Date: Fri, 17 Mar 2023 01:11:59 +0100 [thread overview]
Message-ID: <20230317001203.18425-1-strahinja.p.jankovic@gmail.com> (raw)
This patch set introduces basic emulation of Allwinner WDT.
Since WDT in both A10 and H3 is part of Timer module, the WDT
functionality is added as an overlay in the memory map.
The focus was to enable reboot functionality, so WDT interrupt handling
is not covered in this patch set.
With these patches the `reboot` command can be used for both Cubieboard
and Orangepi-PC in order to restart the system.
Also, Cubieboard avocado tests have been improved to include reboot
steps as well.
v2:
- Cleaned up WDT implementation (changes only in patch 01/04)
- Removed unnecessary checks - instead of changing enum to start from 1,
removed if (!c->regmap[offset]) since it was conflicting enum values
- Reorganized comments
