The "notable" disappearances are:

• the pac193x stanza - there's nothing in mainline linux w.r.t. bindings for this & what is going to appear in mainline linux is going to be incompatible with what is currently in U-Boot.
• operating points - these operating points should not be set at the soc.dtsi level as they may not be possible depending on the design programmed to the FPGA
• clock output names - there are defines for the clock indices, these should not be needed
• the dt maintainers in linux NAKed using defines for IRQ numbers
• the qspi nand, which is not part of the icicle's default configuration is removed.
