Hi All,

This patch series adds CPG wrapper for Renesas RZ/Five SoC. RZ/Five SoC
has almost identical clock structure compared to RZ/G2UL, so
r9a07g043-cpg.c file is re-used to add support for Renesas RZ/Five SoC.

Below is the clock structure reported by Linux with this patch series:

/ # cat /sys/devices/soc0/family
RZ/Five
/ # cat /sys/devices/soc0/machine
Renesas SMARC EVK based on r9a07g043
/ # cat /sys/devices/soc0/revision
0
/ # cat /sys/devices/soc0/soc_id
r9a07g043
/ #
/ # cat /sys/kernel/debug/clk/clk_summary
enable prepare protect duty hardware
clock count count count rate accuracy phase cycle enable
