mmc: meson-mx-sdio: Add a driver for the Amlogic Meson8 and Meson8b SoCs

2017-10-30T10:46:02Z

Add a driver for the SDIO/MMC host found on the Amlogic Meson SoCs. This is an MMC controller which provides an interface between the application processor and various memory cards. It supports the SD specification v2.0 and the eMMC specification v4.41. The controller provides an internal "mux" which allows connecting up to three MMC devices to it. Only one device can be used at a time though since the registers are shared across all devices. The driver takes care of synchronizing access (similar to the dw_mmc driver). The maximum supported bus-width is 4-bits. Amlogic's GPL kernel sources call the corresponding driver "aml_sdio" to differentiate it from the other MMC controller in (at least the Meson8 and Meson8b) the SoCs (they call the other drivers aml_sdhc and aml_sdhc_m8, which seem to support a bus-width of up to 8-bits). This means that there are three different MMC host controller IP blocks from Amlogic (each of them with completely own register layout and features): - "SDIO": 1 and 4 bit bus width, support for high-speed modes up to UHS-I SDR50, part of Meson6, Meson8 and Meson8b (the driver from this patch targets this controller) - "SDHC": 1, 4 and 8 bit bus width, compatible with standard iNAND interface, support for speeds up to HS200 and MMC spec up to version 4.5x, part of Meson8 and Meson8b SoCs (there is no mainline driver for this controller yet) - "SDEMMC": 1, 4 and 8 bit bus width, support for speeds up to HS400 and MMC spec up to version 5.0, part of the Meson GX (64-bit) SoCs (supported by the meson-gx MMC host driver) Signed-off-by: Carlo Caione Signed-off-by: Martin Blumenstingl Signed-off-by: Ulf Hansson

mmc: cavium: Depend on GPIO driver

2017-10-30T10:46:00Z

Without the ThunderX/OcteonTx GPIO driver the MMC driver would not power up any MMC devices. Therefore add a dependency to the GPIO driver and remove the unneeded GPIOLIB dependency. Signed-off-by: Jan Glauber Acked-by: David Daney Signed-off-by: Ulf Hansson

mmc: Kconfig: Enable CONFIG_MMC_SDHCI_IO_ACCESSORS

2017-10-30T10:45:59Z

Enable CONFIG_MMC_SDHCI_IO_ACCESSORS so that SDHC controller specific register read and write APIs, if registered, can be used. Signed-off-by: Vijay Viswanath Acked-by: Adrian Hunter Signed-off-by: Ulf Hansson

mmc: sdhci-omap: Add OMAP SDHCI driver

2017-09-22T08:28:49Z

Create a new sdhci-omap driver to configure the eMMC/SD/SDIO controller in TI's OMAP SoCs making use of the SDHCI core library. For OMAP specific configurations, populate sdhci_ops with OMAP specific callbacks and use SDHCI quirks. Enable only high speed mode for both SD and eMMC here and add other UHS mode support later.

mmc: host: fix typo after MMC_DEBUG move

MMC_DEBUG was moved and one letter got strangely capitalized. Signed-off-by: Wolfram Sang Signed-off-by: Ulf Hansson

mmc: mmci: stop building qcom dml as module

2017-08-30T13:03:53Z

It does not make sense for qcom dml code to be a seperate module, as this has just 2 helper functions specific to qcom, and used directly by mmci driver, so just compile this along with main mmci driver. This would also fix issues arrising due to Kconfig combinations between mmci and qcom dml. Signed-off-by: Srinivas Kandagatla Signed-off-by: Ulf Hansson

MMC: Remove HIGHMEM dependency from mmc-spi driver

2017-08-30T12:01:36Z

I cannot see why this is needed. kmap() should be safe in this case. Signed-off-by: Ian Molton Signed-off-by: Ulf Hansson

mmc: Kconfig: downgrade CONFIG_MMC_DEBUG for host drivers only

2017-08-30T12:01:34Z

We have removed all code depending on CONFIG_MMC_DEBUG from mmc core now. So it's safe to make CONFIG_MMC_DEBUG just for host drivers only and we expect to kill this option in the future. Signed-off-by: Shawn Lin Signed-off-by: Ulf Hansson
