Subject: [PATCH v4 0/3] Add EHCI support for Armada 37xx

Hi,

The EHCI controller in the Armada 37xx SoCs is the one used on many
other mvebu SoCs such as the orion5x, the kirkwood, or the
armada. However, for Armada 37xx an extra initialization step is
needed: this is the purpose of the first patch.

The second patch allows to build the driver for the ARM64 Armada SoCs.

The last one enables the EHCI in the device tree.

This forth version really takes into account the review from Alan Stern.
Again sorry for the noise.

Thanks,

Gregory
