[PATCH v2 0/4] arm64: dts: renesas: Add XSPI support for RZ/V2N and RZ/V2H(P) SoCs and EVK

Hi all,

This patch series adds XSPI support to the Renesas RZ/V2N (R9A09G056)
and RZ/V2H(P) (R9A09G057) SoCs. It introduces the XSPI controller nodes
in the SoC-level DTSI files and enables a connected serial NOR flash
device on the respective evaluation boards.

v1->v2:
- Added Reviewed-by tags from Geert
- Moved assigned-clocks and assigned-clock-rates properties to board DTS

Cheers,
Prabhakar

Thanks, will queue in renesas-devel for v6.17.

    * MT25QU512ABB8E12 flash chip is capable of running at 166MHz
    * clock frequency. Set the maximum clock frequency to 133MHz
    * supported by the RZ/V2N SoC.

Shouldn't that be:

    * clock frequency. Set the clock frequency to the maximum 133MHz
    * supported by the RZ/V2N SoC.

? Or am I misunderstanding?

Thanks!

I agree that the above makes it clearer. Thank you for taking care of it.
