Ok, so you'd rather have a commit for reset definitions (dt-bindings: reset: 
Add rk3576 reset definitions) and another one for clock definitions + 
Documentation (dt-bindings: clock: Add rk3576 clock definitions and 
documentation) ?

Oh right, I suppose "GPL-2.0 OR MIT" is better ? At least that is what I see 
for rk3588. include/dt-bindings/clock/rockchip,rv1126-cru.h uses "GPL-2.0+ OR 
MIT" though.

Why start at 1 ? RK3588 starts at 0 for clocks and resets
