Hello Oleksandr-san, Thank you for the patch!

Linux upstream doesn't support the IPMMU-VMSA driver for R-Car S4 yet, but I believe the following patch can be helpful for R-Car S4: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/iommu/ipmmu-vmsa.c?h=v5.16-rc1&id=7a62ced8ebd0e1b692c9dc4781a8d4ddb0f74792 I have a plan to modify the Linux IPMMU-VMSA driver for R-Car S4 in the future. - The ipmmu_features_r8a779a0 is replaced with ipmmu_features_rcar_gen4. I'll review further patches (8/10 through 10/10) tomorrow or later. Best regards, Yoshihiro Shimoda
