Just sent the patches to the mailing list, please have a look. [2][3] I've "downgraded" the previously proposed "Co-developed-by" tag in the RK356x patch [3] to a "Helped-by" tag, just because the cache-size values in your patch mostly weren't correct and, as a result, differed from the cache-size values in my patch, making the "Co-developed-by" tag technically not applicable. For that tag to be applicable, the most important parts of the patches need to be pretty much identical. I hope you agree.
