Hi Russell,
As explained in the cover-letter there are tight dependencies between the
patches in this series, so for simplicity I'd like to take this patch through
the Tegra tree with your Acked-by.
Thanks,
Thierry
Changes in v4:
- add precursory patch introducing drivers/amba/Kconfig, rebase on top
Changes in v3:
- select ARM_AMBA from ARCH_TEGRA to enable the TEGRA_AHB driver
