In the case of a single clock source, you don't need names. However, if the controller has 2 clock sources, you need to name them correctly so the driver can find the 2nd one. The 2nd clock is for the internal card detect logic.

2016-09-26dt: bindings: Make compatible optional for mmc function nodesHans de Goede1-1/+3
On some boards (android tablets) different batches use different sdio wifi modules. This is not a problem since mmc/sdio is an enumerable bus, so we only need to describe and activate the mmc controller in dt and then the kernel will automatically load the right driver. Sometimes it is useful to specify certain ethernet properties for these "unknown" sdio devices, specifically we want the boot-loader to be able to set "local-mac-address" as some of these sdio wifi modules come without an eeprom / without a factory programmed mac address. Since the exact device is unknown (differs per batch) we cannot use a wifi-chip specific compatible, thus sometimes it is desirable to have a mmc function node, without having to make up an otherwise unused compatible for the node, so make the compatible property optional.

Some SD/eMMC PHYs (like the PHY from Arasan that is designed to work with arasan,sdhci-5.1) need to know the card clock frequency in order to function properly. Physically in a SoC this clock is exported from the SDHCI IP block to the PHY IP block and the PHY needs to know the speed. Let's export the SDHCI card clock using a standard device tree mechanism so that the PHY can get access to it and query the card clock frequency.

2016-07-25Documentation: mmc: sdhci-of-arasan: Add soc-ctl-syscon for corecfg regsDouglas Anderson1-2/+25
As can be seen in Arasan's datasheet [1] there are several "corecfg" settings in their SDHCI IP Block that are supposed to be controlled by software. Although the datasheet referenced is a bit vague about how to access corecfg, in Figure 5 you can see that for Arasan's PHY (a separate component than their SDHCI component) they describe the "phyctrl" registers as being "FROM SOC CTL REG", implying that it's up to the licensee of the Arasan IP block to implement these registers. It seems sane to assume that the "corecfg" registers in their SDHCI IP block works in a similar way for all licensees of the IP Block. Device tree has a model that allows a device to get a reference to random registers located elsewhere in the SoC: sysctl. Let's leverage this model and allow adding a sysctl reference to access the control registers for the Arasan SDHCI PHYs. Having a reference to the control registers doesn't do much for us on its own since the Arasan spec doesn't specify how these corecfg values are laid out in memory. In the SDHCI driver we'll need a map detailing where each corecfg can be found in each implementation. This map can be found using the primary compatible string of the SDHCI device. In that spirit, document that existing rk3399 device trees already have a specific compatible string, though up to now they've always been relying on the driver supporting the generic. Note that since existing devices seem to work fairly well as-is, we'll list the syscon reference as "optional", but it's likely that we'll run into much fewer problems if we can actually set the proper values in the syscon, so it is strongly suggested that any SoCs where we have a map to set the corecfg also include a reference to the syscon.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM 64-bit DT updates from Arnd Bergmann: "We continue ramping up platform support for 64-bit ARM machines, with 111 individual non-merge changesets touching 21 platforms. The LG1312 platform is completely new and is the first ARM platform by LG that we support in the mainline kernel. Two other SoCs got added that are updated versions of existing SoC families, so the port mainly consists of new dts files: - The Hisilicon Hip06/D03 is the latest server platform from Huawei/Hisilicon, and follows the Hip05/D02 platform. - Rockchip RK3399 follows the 32-bit RK3288 that is popular in low-end Chromebooks and the 64-bit RK3368 that is mainly found in chinese Android TV boxes. The 96Boards HiKey based on the Hisilicon Hi6220 (Kirin 620) gets a long-awaited overhaul with a lot of devices enabled in the DT, so it should be much more usable with a mainline kernel now. See also https://plus.google.com/111524780435806926688/posts/PeGb2VsNhJd A lot of work went into enabling new device drivers on existing machines, but we also have a couple of new commercially available machines: - Google Pixel C laptop based on Tegra210 - Hardkernel Odroid C2 Based on Amlogic Meson GXBB (S905) - Geekbuying GeekBox based on Rockchip RK3368 And finally, a couple of reference or development platforms that are not end-user platforms but are used for trying out the respective SoC platforms: - Amlogic Meson GXBB P200 and P201 development systems - NXP Layerscape 1043A QDS development board - Hisilicon Hip06 D03 server board, as mentioned above - LG1312 Reference Design - RK3399 Evaluation Board" * tag 'armsoc-dt64' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (104 commits) arm64: dts: marvell: add XOR node for Armada 3700 SoC dt-bindings: document rockchip rk3399-evb board arm64: dts: rockchip: add dts file for RK3399 evaluation board arm64: dts: rockchip: add core dtsi file for RK3399 SoCs dt-bindings: rockchip-dw-mshc: add description for rk3399 arm64: dts: marvell: Use a SoC-specific compatible for xHCI on Armada37xx arm64: dts: marvell: Rename armada-37xx USB node arm64: dts: marvell: Clean up armada-3720-db Documentation: arm64: Add Hisilicon Hip06 D03 dts binding arm64: dts: Add initial dts for Hisilicon Hip06 D03 board arm64: dts: hip05: Add nor flash support arm64: dts: hip05: fix its node without msi-cells arm64: dts: r8a7795: Don't disable referenced optional clocks arm64: dts: salvator-x: populate EXTALR arm64: dts: r8a7795: enable PCIe on Salvator-X arm64: dts: r8a7795: Add PCIe nodes arm64: tegra: Add IOMMU node to GM20B on Tegra210 arm64: tegra: Add reference clock to GM20B on Tegra210 dt-bindings: Add documentation for GM20B GPU dt-bindings: gk20a: Document iommus property ...

Pull MMC updates from Ulf Hansson: "MMC core: - Fix ABI regression of MMC BLK ioctl - Remove the unused MMC_DATA_STREAM flag - Enable asynchronous system PM for the host device - Minor fixes and clean-ups SDHCI host: Throughout the years, the numbers of SDHCI variants have increased and so has also the numbers of SDHCI callbacks/quirks. The purpose of these callbacks/quirks were to enable SDHCI to deal with variant specific requirements, but unfortunate this method didn't scale. Instead we have ended up with a mess. Not only did the code become suboptimal but also highly fragile. Lately many discussions of how to move forward with SDHCI has taken place at the MMC mailing list. Step by step, we aim to turn SDHCI's common code into a set of library functions. This will enable for optimizations and allow some of the existing callbacks and quirks to be removed, which also should help to make the code less fragile. Therefore I am also really pleased to announce that Adrian Hunter (Intel) has volunteered to step in as the maintainer for SDHCI. Future wise, I hope the community around SDHCI will continue to grow and that this release cycle can be the starting point of moving SDHCI into a better shape. As a matter of fact, already in this cycle the re-factoring has begun, but of course there are also fixes and new features included. Some highlights: - sdhci-iproc: Add support for Broadcom's BCM2835 eMMC IP - sdhci-acpi: Add support for QCOM controllers - sdhci-pic32: Add new SDHCI variant for PIC32MZDA Other hosts: - atmel-mci: Fix a NULL pointer dereference - mediatek: Add SD write-protect support - mmc_spi: Fix card detect in GPIO case - tmio/sdhi: Add r8a7795 support - tmio/sdhi: Some fixes and clean-ups - dw_mmc: Add HW reset support - dw_mmc: Some fixes and clean-ups - sunxi: Add support for MMC DDR52 mode" * tag 'mmc-v4.6' of git://git.linaro.org/people/ulf.hansson/mmc: (123 commits) mmc: sdhci-of-at91: fix wake-up issue when using runtime pm mmc: sdhci-pci: Do not set DMA mask in enable_dma() mmc: sdhci-acpi: Remove enable_dma() hook mmc: sdhci: Set DMA mask when adding host mmc: block: fix ABI regression of mmc_blk_ioctl mmc: atmel-mci: Check pdata for NULL before dereferencing it at DMA config mmc: core: remove redundant memset of sdio_read_cccr mmc: core: remove redundant memset of mmc_decode_cid mmc: of_mmc_spi: fix unused warning mmc: sdhci-of-arasan: add phy support for sdhci-of-arasan mmc: sdhci-of-arasan: fix missing sdhci_pltfm_free for err handling mmc: sdhci-of-arasan: remove disable clk_ahb from sdhci_arasan_resume Documentation: bindings: add description of phy for sdhci-of-arasan mmc: sdhci: Fix override of timeout clk wrt max_busy_timeout mmc: mmci: Remove unnecessary header file mmc: sdhci-acpi: add QCOM controllers mmc: tegra: implement memcomp pad calibration mmc: mediatek: Use mmc_regulator_set_vqmmc in start_signal_voltage_switch mmc: mediatek: Change signal voltage error to dev_dbg() mmc: sh_mmcif, tmio: Use ARCH_RENESAS ...

Registers are 64bit apart, so we refactor bus_shift handling a little and set it based on the DT compatible. Also, EXT_ACC is different. It has been tested on a Salvator-X (Gen3) and, to check for regressions, on a Lager (Gen2).
