Shimoda-san, do we also need 'CONFIG_DW_EDMA' for endpoint mode? There
is a BSP patch suggesting that: cda3dd982572 ("arm64: defconfig: Updated
for RCAR_GEN4 PCIe driver")

Thank you for asking me about this. Yes, since enabling the config improves
the performance in endpoint mode, I would like to enable the config.

Best regards,

Do you plan to send a v2 including that?

I guess we also want that in renesas_defconfig...

Yes, I'll send this later today.
