Dependent DTS are adjusted accordingly. https://lore.kernel.org/linux-arm-kernel/20201112183538.6805-1-nm@xxxxxx/ reversal all over again. Is there a specific pattern we are intending to use here? Because, if we are going down this path (which would be a major churn across multiple downstream trees as well) - I'd rather have this as a documented standard and not just a TI approach and will need to be done across all K3 devices. Are you aware of such a documented guideline, rather than "word of mouth"?
