[PATCH 00/12] Add SDHCI Xenon driver

[Gregory CLEMENT]

Hello,

This series adds support for the SDHCI Xenon controller which can be
found on the Armada 37xx and the Armada 7K/8K.

This series currently only enables the support on the Armada 37xx SoCs
and boards. More tests are needed to enable it on the A7K/A8K.

Following the new trend for the MMC subsystem, instead of introducing
new quirks for this controller we extend the mmc/sdhci framework by
adding callbacks when needed.

Thanks,

Gregory
