[PATCH v4 00/15] arm64: dts: renesas: r8a7795: IPMMU upstream integration

[PATCH v4 00/15] arm64: dts: renesas: r8a7795: IPMMU upstream integration

[Simon Horman]

This series adds DT nodes for IPMMU instances on r8a7795 together with
connections to various r8a7795 on-chip devices such as Audio-DMAC, SYS-DMAC,
Ethernet-AVB, SATA and a bunch of multimedia devices that make use of FCP.

With these patches applied a white list enabled IPMMU driver may be used
to check silicon revision and then enable IPMMU in the known working cases.

The recommended IPMMU driver patch is iommu/next with the following applied:
 [PATCH v5 00/09] iommu/ipmmu-vmsa: r8a7795 support V5

The final two patches in the series enable IPMMU support for all IPMMU
instances on r8a7795 that are used by IPMMU devices listed above with one
exception.  The exception is the SATA device connected to IPMMU-HC which
still is disabled pending IPMMU USB integration support. I expect IPMMU USB
integration to be handled as a second step once this series is agreed on.

The DT binding for r8a7795 has since long been included in mainline and
this series implements support following such format:

d4e42e7 iommu/ipmmu-vmsa: Add r8a7795 DT binding

Changes since V3:
 - Rework to support ES2.0
 - Other minor changes as noted in per-patch changelogs

Changes since V2:
 - Added the iommus property before power domains - thanks Geert!
 - Added reviewed-by to patch 2 and 3 from Laurent - thanks!
 - Re-added Ethernet and FCPVD patches (They were present in V1 but not V2)
 - Added remaining FCP devices such as FCPF, FCPVB and FCPVI
 - Added SATA device
 - Added final patch to enable various IPMMU devices in the DTS file

Since the DT binding has been merged quite some time ago and the interface
seems stable enough I see no reason not to queue these up for upstream merge.

This is a minor rework of work by Magnus Damm.

Given the label names, do we need comments like "IPMMU-VI0"?

described in DT nevertheless.

Do we sort labels alphabetically?
Or do we follow the order of the original targets?

we decided on a scheme to adopt.
