no enable-method?
As the rk3228 also does not have a pmu, does the newly created
"rockchip,rk3036-smp" work for you?

these clocks starting with hdmiphy clock come from IPs in the soc, so the
relevant drivers should provide them (see my patch series for the picophy,
or how rk808 and hym8563 do it) - especially as these clocks might get
turned off in the IP-block itself.
The clock framework can handle orphans, so just leave these out for now
please.

please order by register address, so gic should move quite
a bit lower.

please separate board and core properties.
broken-cd, cap-*, mmc-ddr-1_8v, disable-wp, non-removable
are per-board properties as they depend on what is connected to
the controller.
