Subject: [PATCH v6 03/12] ARM: tegra: Move AHB Kconfig to drivers/amba
Date: Fri,  7 Nov 2014 17:00:54 +0100	[thread overview]
Message-ID: <1415376063-17205-4-git-send-email-thierry.reding@gmail.com> (raw)
In-Reply-To: <1415376063-17205-1-git-send-email-thierry.reding@gmail.com>

From: Thierry Reding <treding@nvidia.com>

This will allow the Kconfig option to be shared among 32-bit and 64-bit
ARM.

Signed-off-by: Thierry Reding <treding@nvidia.com>

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
