mmc: sdhci_am654: Add Initial Support for AM654 SDHCI driver

2018-12-17T07:26:24Z

The host controllers on TI's AM654 SOCs are not compatible with the phy and consumer model of the sdhci-of-arasan driver. It turns out that for optimal operation at higher speeds, a special tuning procedure needs to be implemented which involves configuration of platform specific phy registers. Therefore, branch out to a new sdhci_am654 driver and add the phy register space with all phy configurations to it. Populate AM654 specific callbacks to sdhci_ops and add SDHCI_QUIRKS wherever applicable. Only add support for upto High Speed for SD card and upto DDR52 speed mode for eMMC. Higher speeds will be added in subsequent patches. Signed-off-by: Faiz Abbas Acked-by: Adrian Hunter Signed-off-by: Ulf Hansson

mmc: mmci: add stm32 sdmmc variant

2018-10-09T07:16:53Z

This patch adds a stm32 sdmmc variant, rev 1.1. Introduces a new Manufacturer id "0x53, ascii 'S' to define new stm32 sdmmc family with clean range of amba revision/configurations bits (corresponding to sdmmc_ver register with major/minor fields). Add 2 variants properties: -dma_lli, to enable link list support. -stm32_idmabsize_mask, defines the range of SDMMC_IDMABSIZER register which specify the number bytes per buffer. DT properties for sdmmc: -Indicate signal directions (only one property for d0dir, d123dir, cmd_dir) -Select command and data phase relation. -Select "clock in" from an external driver.

mmc: sdhci-sprd: Add Spreadtrum's initial host controller

2018-10-08T09:40:43Z

This patch adds the initial support of Secure Digital Host Controller Interface compliant controller found in some latest Spreadtrum chipsets. This patch has been tested on the version of SPRD-R11 controller. R11 is a variant based on SD v4.0 specification. With this driver, R11 mmc can be initialized, can be mounted, read and written.

mmc: uniphier-sd: add UniPhier SD/eMMC controller driver

2018-10-08T09:40:43Z

Here is another TMIO MMC variant found in Socionext UniPhier SoCs. As commit b6147490e6aa ("mmc: tmio: split core functionality, DMA and MFD glue") said, these MMC controllers use the IP from Panasonic. However, the MMC controller in the TMIO (Toshiba Mobile IO) MFD chip was the first upstreamed user of this IP. The common driver code for this IP is now called 'tmio-mmc-core' in Linux although it is a historical misnomer. Anyway, this driver select's MMC_TMIO_CORE to borrow the common code from tmio-mmc-core.c Older UniPhier SoCs (LD4, Pro4, sLD8) support the external DMA engine like renesas_sdhi_sys_dmac.c. The difference is UniPhier SoCs use a single DMA channel whereas Renesas chips request separate channels for RX and TX. Newer UniPhier SoCs (Pro5 and later) support the internal DMA engine like renesas_sdhi_internal_dmac.c The register map is almost the same, so I guess Renesas and Socionext use the same internal DMA hardware. The main difference is, the register offsets are doubled for Renesas. Renesas Socionext SDHI UniPhier DM_CM_DTRAN_MODE 0x820 0x410 DM_CM_DTRAN_CTRL 0x828 0x414 DM_CM_RST 0x830 0x418 DM_CM_INFO1 0x840 0x420 DM_CM_INFO1_MASK 0x848 0x424 DM_CM_INFO2 0x850 0x428 DM_CM_INFO2_MASK 0x858 0x42c DM_DTRAN_ADDR 0x880 0x440 DM_DTRAN_ADDREX --- 0x444 This comes from the difference of host->bus_shift; 2 for Renesas SoCs, and 1 for UniPhier SoCs. Also, the datasheet for UniPhier SoCs defines DM_DTRAN_ADDR and DM_DTRAN_ADDREX as two separate registers. It could be possible to factor out the DMA common code by introducing some hooks to cope with platform quirks, but this patch does not touch that for now.

mmc: sdhci-pci-dwc-mshc: synopsys dwc mshc support

2018-07-16T09:21:45Z

Synopsys has DWC MSHC controller on HPAS-DX platform connected using PCIe interface with SD card slot and eMMC device slots. This patch is to enable SD cards connected on this platform. As Clock generation logic is implemented using MMCM module of HAPS-DX platform, we have separate functions to control the MMCM to generate required clocks with respect to speed mode.
