>> 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,
