I think this could do with slightly more explanation. I.e. we want a single firmware build which can work with both kernel drivers by specifying both sets of properties, which is useful during the transition phase. And maybe mention the kernel versions in which the old driver was removed and the new driver added.

This is not true, since the new properties will be added to the ACPI tables with zero values.

Could you add a few more details, similar to what I suggested for the commit message?
