+description:
+ On the FU540 family of SoCs, most system-wide clock and reset integration
+ is via the PRCI IP block.
+ The clock consumer should specify the desired clock via the clock ID
+ macros defined in include/dt-bindings/clock/sifive-fu540-prci.h.
+ These macros begin with PRCI_CLK_.
+
+ The hfclk and rtcclk nodes are required, and represent physical
+ crystals or resonators located on the PCB. These nodes should be present
+ underneath /, rather than /soc.
