Hi All,
This patch series adds device nodes for IPMMU, DMAC, GPIO
and AVB nodes for RZ/G2H (R8A774E1) SoC.
Cheers,
Prabhakar

Hi Geert,
Thank you for the review.

I think the comment "For R-Car Gen3 use a white list to opt-in slave
devices." is misleading. Booting through the kernel I do see iommu
groups (attached is the logs). Also the recent patch to add
"r8a77961" just adds to soc_rcar_gen3_whitelist.
Cheers,

I think the comment "For R-Car Gen3 use a white list to opt-in slave
devices." is misleading. Booting through the kernel I do see iommu
groups (attached is the logs). Also the recent patch to add
"r8a77961" just adds to soc_rcar_gen3_whitelist.
Cheers,

Indeed. Without an entry in soc_rcar_gen3[], the IPMMU is enabled
unconditionally, and soc_rcar_gen3_whitelist[] is ignored.
That's why you want an entry in both, unless you have an R-Car Gen3
SoC where the IPMMU works correctly with all slave devices present.
Perhaps soc_rcar_gen3[] should be renamed to soc_rcar_gen3_greylist[]
(or soc_rcar_gen3_maybelist[]) to make this clear?

Oops, commit 17fe16181639801b ("iommu/renesas: Add support for r8a77961")
did it wrong, too.

I think so (we should rename it).

Thank you for the point it out. We should add r8a77961 to the soc_rcar_gen3[].
However, I don't know why I could not realize this issue...
So, I investigated this a little and then, IIUC, glob_match() which
soc_device_match() uses seems to return true, if *pat = "r8a7796" and *str = "r8a77961".
Best regards,

Thank you for the point it out. We should add r8a77961 to the soc_rcar_gen3[].
However, I don't know why I could not realize this issue...
So, I investigated this a little and then, IIUC, glob_match() which
soc_device_match() uses seems to return true, if *pat = "r8a7796" and *str = "r8a77961".
Best regards,

Are you sure about this?
I enabled CONFIG_GLOB_SELFTEST, and globtest succeeded.
It does test glob_match("a", "aa"), which is a similar test.
To be 100% sure, I added:
--- a/lib/globtest.c
+++ b/lib/globtest.c
@@ -59,6 +59,7 @@ static char const glob_tests[] __initconst =

I'm very sorry. I completely misunderstood the glob_match() behavior.
And, now I understood why the current code can use IPMMU on r8a77961...
# Since the first soc_device_match() will return false, ipmmu_slave_whitelist()
# will return true and then the ipmmu_of_xlate() will be succeeded.
