There are totally 19 instances of watchdog module. One each for the
8 A72 cores, one each for the 4 C7x cores, 1 for the GPU, 1 each
for the 6 R5F cores in the main domain. The non-A72 instances are
coupled with the R5Fs, C7x & GPU instances. Keeping them as reserved as
they are not used by A72.

There are totally 2 instances of watchdog module in MCU domain.
These instances are coupled with the MCU domain R5F instances.
Disabling them as they are not used by Linux.

There are totally 9 instances of watchdog module. One each for the
2 A72 cores, one each for the 2 C7x cores, 1 for the GPU, 1 each
for the 4 R5F cores in the main domain. Keeping only the A72 instances
enabled and reserving the rest by default as they will be used by
their respective firmware.

There are totally 2 instances of watchdog module in MCU domain.
These instances are coupled with the MCU domain R5F instances.
Reserving them as they are not used by A72.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
