Hi Prabhakar,
Thanks for the patch.

Just a question,
Why can't we reuse SoC dtsi as well, as 90% of the SoC nodes are same?
Split common stuff from arch/arm/boot/dts/renesas/r9a07g043.dtsi
and add ARM specific CPU, IRQ to arch/arm/boot/dts/renesas/r9a07g043u.dtsi
RISC-V specific CPU, IRQ to arch/riscv/boot/dts/renesas/r9a07g043f.dtsi
Both r9a07g043{u,f} dtsi will add common dtsi.
Cheers,
Biju
