[PATCH 0/2] amba/iommu: tegra: enable compile testing

[Johan Hovold]

There seems to be nothing preventing us from enabling compile testing of
the Tegra AHB and IOMMU drivers so enable that to increase build
coverage.

Note that these could go in through separate trees, but compile testing
of the IOMMU driver does depend on the AHB driver being enabled.

[PATCH 1/2] amba: tegra-ahb: enable compile testing

[Johan Hovold]

There seems to be nothing preventing this driver from being compile
tested so enable that to increase build coverage.

This also allows for compile testing of further Tegra drivers (e.g.
IOMMU driver).

Joerg, could you consider taking also the amba patch through the iommu
tree as a dependency with the nVidia guys' acks?
