Subject: [PATCH] dt-bindings: iommu: renesas,ipmmu-vmsa: add r8a779h0 support
Date: Fri, 19 Apr 2024 13:42:11 +0200 [thread overview]
Message-ID: <13643259be4e8a8e30632de622ad7c685dbb7c61.1713526852.git.geert+renesas@glider.be> (raw)
From: Thanh Le <thanh.le.xv@renesas.com>
Document support for the I/O Memory Management Unit (IPMMU) on the
Renesas R-Car V4M (R8A779H0) SoC.
Signed-off-by: Thanh Le <thanh.le.xv@renesas.com>

Interestingly, the IMSSTR register is documented for R-Car V4M, unlike
for R-Car S4 and R-Car V4H, so the second cell of the renesas,ipmmu-main
property could be added again.
As nothing really uses this register and the associated bit numbers,
I think it is better to keep it simple, and not partially revert commit
b67ab6fb63bbbe6d ("dt-bindings: iommu: renesas, ipmmu-vmsa: Update for
R-Car Gen4").
