Before sending another round of patches, just to make sure we are on the same page, please confirm that what remains is Subject: dt-bindings: rng: Add Rockchip RNG bindings which not only should be 'rng' in small letters but also name the exact chip, eg.: Subject: dt-bindings: rng: add TRNG on the Rockchip RK3568 SoC If there are any other comments you made which I'm not aware of, please point me to them. Cheers Daniel

And where did you drop the redundant bindings? You just quoted the sentence and ignored it. Best regards, Krzysztof
