Hello, This the fifth 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). v4->v5: - Remove the patch to export sdhci_execute_tuning(). It is already exported in v4.10. - Introduce a patch adding a missing clock for the sdhci controller present on the CP master for A7K/A8K. There is no build dependency but obviously this patch is need to use the sdhci controller present on the CP part. - Adjust Xenon return setup, to avoid being overwritten by sdhci_add_host(). - Change Xenon register definition prefix to "XENON_". - Fix typos in Xenon driver and dt-binding docs. - Change compatible string "marvell,armada-7000-sdhci" to "marvell,armada-8k-sdhci". Actually the Armada 7K SoCs are a subset of the Armada 8K SoCs. Moreover, the use of the '000' is not consistent with all the other compatible string already used for the Armada 7K/8K family. - Added the Tested-by from Russell King on an Armada 8K based board. 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."
