You break users, which might be ok, but commit does no say > that anything was broken here. Per, https://lore.kernel.org/all/02e25e44-1146-bb59-58de-800b11d30e7b@linaro.org/ I thought we agree they are not HW compatible, it is SW trick to make Linux driver could work with both with i.MX7ULP compatible.
I will add more information in commit to describe breaking users. BTW: in linux driver in this patchset, I have added code to support legacy bindings.
Thanks, Peng.
