[PATCH v4 00/12] mmc: Add support to Marvell Xenon SD Host Controller

[Gregory CLEMENT]

Hello,

This the forth 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).

v3 -> v4:
For this version a few change have been done:
- fixes 2 bug  reported by kbuild-bot
  - remove extra of_node_put()
  - convert 0 in false for function returning boolean

- add a device tree node for the sdhci controller present on the CP
  master for A7K/A8K. It also led to rename the sdhci0 node on AP to
  ap_sdhci0 to make a distinction with the one present on CP master.

v2 -> v3
I think that now most (if not all) the remarks had been taking into
account since the second version. According to Ziji Hu, here are the
following changes:
" Changes in V3:
  Adjust and improve Xenon DT bindings. Move some caps setting from driver into
  DT. Use mmc-card sub-node to represent eMMC type.
  Remove PHY Sampling Fixed Delay Line scan in lower speed mode.
  Improve Xenon probe and ->init_card() functions.
  Export sdhci_enable_sdio_irq() and implement own SDIO IRQ control.
  Split PHY patch into two smaller patches.
  Temporarily remove AXI clock before its implementation is improved."

Besides this changes I also
- Removed the sdhci-xenon-phy.h and moved its content in the
shc-xenon-phy.c file.
- Fixed the tuning-count usage
- Managed the error case for clk_prepare_enable

For the record the change from v1 was:
" 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."

Thanks,

Gregory
