I double checked around here, and noticed some miss on it. Thank you for pointing it. I will fixup in v2. About power, indeed we can find many 3v3 / GND pins on WhiteHawk. But to keep simple Image I will use similar style, but will add small explanation for it on v2. > > +/dts-v1/; > > +#include "r8a779g0-white-hawk.dts" > > Please do not include "r8a779g0-white-hawk.dts", but make this file > a .dtso (DTS overlay) instead, cfr. salvator-panel-aa104xd12.dtso.

Thank you for pointing it. I didn't noticed about it, will fix in v2. And as you mentioned, we can remove [6/9] patch. Thank you for your help !! Best regards --- Kuninori Morimoto
