I would like to reuse an upstream-based patch instead of this BSP 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
