2018-10-08mmc: sdhci-of-esdhc: add erratum A008171 supportYinbo Zhu2-1/+44
In tuning mode of operation, when TBCTL[TB_EN] is set, eSDHC may report one of the following errors : 1)Tuning error while running tuning operation where SYSCTL2[SAMPCLKSEL] will not get set even when SYSCTL2[EXTN] is reset. OR 2)Data transaction error (e.g. IRQSTAT[DCE], IRQSTAT[DEBE]) during data transaction errors. This issue occurs when the data window sampled within eSDHC is in full cycle. So, in that case, eSDHC is not able to find out the start and end points of the data window and sets the sampling pointer at default location (which is middle of the internal SD clock). If this sampling point coincides with the data eye boundary, then it can result in the above mentioned errors. Impact: Tuning mode of operation for SDR50, SDR104 or HS200 speed modes may not work properly Workaround: In case eSDHC reports tuning error or data errors in tuning mode of operation, by add the erratum A008171 support to fix the issue.

2018-10-08mmc: uniphier-sd: add UniPhier SD/eMMC controller driverMasahiro Yamada4-0/+705
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.

2018-10-08mmc: tmio: move tmio_mmc_set_clock() to platform hookMasahiro Yamada4-89/+117
tmio_mmc_set_clock() is full of quirks because different SoC vendors extended this in different ways. The original IP defines the divisor range 1/2 ... 1/512. bit 7 is set: 1/512 bit 6 is set: 1/256 ... bit 0 is set: 1/4 all bits clear: 1/2 It is platform-dependent how to achieve the 1/1 clock. I guess the TMIO-MFD variant uses the clock selector outside of this IP, as far as I see tmio_core_mmc_clk_div() in drivers/mfd/tmio_core.c I guess bit[7:0]=0xff is Renesas-specific extension. Socionext (and Panasonic) uses bit 10 (CLKSEL) for 1/1. Also, newer versions of UniPhier SoC variants use bit 16 for 1/1024. host->clk_update() is only used by the Renesas variants, whereas host->set_clk_div() is only used by the TMIO-MFD variants. To cope with this mess, promote tmio_mmc_set_clock() to a new platform hook ->set_clock(), and melt the old two hooks into it.
