So you never tested your DTS... We can keep asking about this but still
testing does not happen :/
Since this new property has not been applied on the exist upstream DTS,
I tested this driver with the

local DTS. Unfortunately, the property name in the local DTS is not
updated, this is why it is not found
But your local DTS would not pass dtbs_check tests, so that's why I am
saying - you never tested it on mainline kernel.

Thanks, we will add this test in the future to ensure that DTS, doc and driver are consistent.


Best,
