Re: Adding flag to disable native mode on aceride



My goal is to not rely on driver names in MD code. Yes, I know we already violate this in many places... Anyway, my point is that you don't need to test for "aceride".

you should consult the actual PCI bus/device/function numbers, the way
other platforms fix-up MI drivers for MD quirks.

Done.

The name of the property should reflect that it's aceride-specific (and not have a name that ties it to the driver): ali1543-ide-force- compat-mode

Also done.

I also took note of Jachym suggestion to use
prop_dictionary_{get|set}_bool functions, rather than manipulating a
prop_bool.

Does the attached diff look ok?  I'm hoping to check it in this week.

Thanks,
Chris
