This is not the correct fixes tag. The one I meant to put was:
Fixes: 528a5b1f2556 ("riscv: dts: microchip: add new peripherals to icicle kit device tree")

However, that's the commit the RTC was added in but not the refclk.
Can I have two fixes tags? The other one would be:
Fixes: 0fa6107eca41 ("RISC-V: Initial DTS for Microchip ICICLE board")

Although that seems like a sign that this should really be two commits...
