Thanks for this reply.

Exactly, on sparx5 syscon is shared...
$ git grep 'microchip,sparx5-cpu-syscon'
...
arch/arm64/boot/dts/microchip/sparx5.dtsi:                      
compatible = "microchip,sparx5-cpu-syscon", "syscon",
drivers/mmc/host/sdhci-of-sparx5.c:     const char *syscon = 
"microchip,sparx5-cpu-syscon";
drivers/power/reset/ocelot-reset.c:     .syscon          = 
"microchip,sparx5-cpu-syscon",
drivers/spi/spi-dw-mmio.c:      const char *syscon_name = 
"microchip,sparx5-cpu-syscon";
$

Ok, got it. In that case, your suggestion looks fine.
