This is also part of imx53.dtsi. This is necessary because the USB armory mounts a i.MX534 and it does not support the 1 and 1.2 GHz operating point.

No status equals to status = "okay". We have status = "disabled" in <soc>.dtsi and explicitly enable it by changing status to "okay" for devices which have pin out on board. For devices like VPU, DMA which is completely SoC internal, we simply do not use status and have them always enabled. Shawn
