Converting to DM increases binary size and breaks building some boards (i.e. tbs2910, gcc 9.2). The approach to address this issue via cutting off unused properties/nodes in device tree via custom u-boot.dtsi was not welcome, even if the affected boards do not pass the built-in device tree to the kernel.
But there is CONFIG_OF_REMOVE_PROPS="dmas dma-names interrupt-parent interrupts interrupts-extended interrupt-names interrupt-map interrupt-map-mask" in tbs2910_defconfig. So removing properties is already done via this config option. Removing nodes is not implemented (yet? AFAIK). But would be welcome if someone implements this in a similar way, I think.
Yes, I've added this CONFIG_OF_REMOVE_PROPS list on request because an earlier patch [1] was not very welcome. But this older patch already did deleting unused nodes, in a different way.
