[PATCH v2 0/4] dmaengine: sh: rcar-dmac: add R-Car Gen5 X5H support

[Wolfram Sang]

Here is a small series with the needed driver updates to support R-Car
Gen5 and X5H for the SYSC-DMAC. Details are in the patch descriptions,
but it is all small stuff.

It has been tested on an Ironhide board (X5H) and a SparrowHawk (V4H)
for regression testing. The testing branch can be found here:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/x5h/i2c-experimental

The patches here are based on linux-next as of 20260908. DT checks have
also been passed.

Looking forward to comments or approval!

Changes since v1:
* tags added (Thanks Krzysztof, Geert and Frank)
* renamed the ipmmu-flag variable
* some updates to commit messages and comments

[Wolfram Sang]

Also add the familiy compatible because X5H is the first R-Car Gen5 SoC.

Every patch reviewed and tagged twice (thank you, guys!), no complaints
from Sashiko even - can we have this in 7.4 pretty please?
