do i need to fix the errors for qcom-compatibles/reg-count/clock-count (reported by your bot) *now*?

or is binding well enough with adding berlin-compatible and fixing the indentation error in example?

for the marvell anyof issue and the spear13xx i have a patch in my tree which i include in v6

i see it as requirement for last part

"arm64: dts: rockchip: Add sata nodes to rk356x"

if this can applied without the bindings conversion there is nothing to hurry :)
