Subject: [PATCH 0/10] mmc: Add support to Marvell Xenon SD Host Controller

Hello,

This series adds support for the SDHCI Xenon controller which can be
currently found on the Armada 37xx and the Armada 7K/8K but will be
also used in more Marvell SoC (and not only the mvebu ones actually).

A few months ago a series has been sent to support this controller:
http://lists.infradead.org/pipermail/linux-arm-kernel/2016-June/434925.html

However, since this first version, the engineer team in charge of this
controller wished to have a better involvement in the mainline support
of the driver. This new series is the result the Marvell development
with the aim of supporting more feature that only the ones needed for
the Armada 3720 SoC.

About the hardware and the driver itself, according to Ziji Hu:
"Marvell Xenon SDHC is widely used in Marvell products.
It supports SD/SDIO/eMMC.
It conforms to SD Physical Layer Specification Version 3.01 and
is designed according to the guidelines provided in the SD Host
Controller Standard Specification Version 3.00.
Xenon SDHC IP contains PHY. There are tree types of Xenon PHY in use.
Each Xenon SDHC only contain one type of PHY."

Thanks,

Gregory
