I took a quick look at these. Neither are simple drop in patches. The
first has only been tested on a custom device and is a complete new
driver.
The second one plays around the with main hal_IRQ_handler which is
definitely not allowed.
I don't have this hardware either.
To make some forward progress on this i suggest you, Oyvind or someone
else with hardware, plays with the submissions and produce a clean,
well tested patch which i can just commit. Also if you do use any of
the code in these two submissions we will need copyright assignment
from the original authors as well.
