That's not good, that's a regression in behavior. The driver should have a fallback when the properties are not present to avoid regressions like these. Please work with the driver maintainer to either get them to revert their change that regresses you, or promptly fix it appropriately with fallback values. Also, the driver changes were commited back in March, with plenty of time to land DT changes well before the merge window. Waiting until the merge window is closed is not appropriate -- this should have come in earlier. -Olof
