I've noticed a while ago that we had a pretty creative approach to the
arch timer trigger, with some platform describing as edge-triggered
something that is architecturally a level interrupt.
This short patch series tries to address it in two ways:
- Enforce the level aspect of the interrupt in the timer driver (and
shout at the user if the firmware describes it as edge)
- Repaint all the in-tree platforms that are obviously doing the wrong
thing.
Hopefully, this will stop DTs that are wrong from being blindly
copy/pasted.
Thanks,
M.
- From v2: Fix all in-tree device-trees.
