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

Hello,

This the second version of the series adding support for the SDHCI
Xenon controller. It 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).

Some of the remarks had been taking into account since the first
version, according to Ziji Hu, here are the following chcanges:
"Changes in V2:
  rebase on v4.9-rc2.
  Re-write Xenon bindings. Ajust Xenon DT property naming.
  Add a new DT property to indicate eMMC card type, instead of using
  variable card_candidate.
  Clear quirks SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12 in Xenon platform data
  Add support to HS400 retuning."

I think the main open point which remains is about issuing commands
from the ->set_ios() callback (in patch 7).
Ulf, could you comment about it?

Thanks,

Gregory
