[PATCH 0/2] Add missing #iommu-cells on IOMMU nodes

[Suman Anna]

Hi Tony,

This series adds the #iommu-cells property to the existing
IOMMU nodes on OMAP4 & OMAP5. It was already fixed for OMAP3
in commit 2055088b5e17 ("ARM: dts: omap3: Add #iommu-cells to
isp and iva iommu").

OMAP4 and OMAP5 do not yet have users for these IOMMUs (remoteproc
nodes), so the warning as seen with the fix added for OMAP3 is not
seen yet, but will as soon as a user is added.

Patches based on 4.2-rc1.

regards
Suman

[PATCH 1/2] ARM: dts: OMAP4: Add #iommu-cells property to IOMMUs

[Suman Anna]

Add missing #iommu-cells property to the DSP and IPU IOMMU nodes
for OMAP4 platforms. This property is required as per the generic
iommu binding.

Applying both into omap-for-v4.2/fixes thanks.
