Hello, This the seventh 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). v6->v7: - Add comments on vqmmc and vmmc in examples in dt binding doc. - Fix all the issues pointed out by Ulf and Adrian: - Align the prefix of function and variable names. - Replace the if-else with switch statements when checking MMC_TIMING_* - Remove the spinlocks in set_ios. - Optimize the delay loop as Adrian patch does. - Add release of phy params structures - Add check of Vqmmc supply in Xenon signal voltage switch. If Vqmmc regulator doesn't exist, skip standard SD signal voltage regulator switch process. - Remove parse of child node mmc-card. Wait for a better solution. v5->v6: - Add a generic "mmc-card" parse in core layer. - Fix the spelling issues in Xenon dt binding doc and drivers. - Remove descriptions to common mmc properties from Xenon dt binding doc. - Split compatible string "marvell,armada-8k-sdhci" into "marvell,armada-ap806-sdhci" and "marvell,armada-cp110-sdhci". - Also updates the example in Xenon dt binding doc. - Remove unnecessary dependency on MMC_SDHCI from Xenon entry in Kconfig. - Move Xenon specific dt parse into a separate function. - Adjust warnings and condition check in Xenon PHY setting, to remove fragile hs200->hs400/hs400->hs200 sequence check function. - Enable PHY Slow Mode in MMC_TIMING_LEGACY timing if PHY Slow Mode is required in dts. - Add a patch allowing dts backwards compatible for the clock 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."
