2019-02-25mmc: renesas_sdhi: Change HW adjustment register according to speed modeTakeshi Saito
SCC is used for SDR104/HS200/HS400. We need to change SCC_DT2FF according to the mode. If it is inappropriate, CRC error tends to occur. This adds variable "tap_hs400" for HS400 mode and configures SCC_DT2FF as needed.

2017-12-19mmc: tmio, renesas_sdhi: move struct tmio_mmc_dma to renesas_sdhi.hMasahiro Yamada
struct tmio_mmc_dma looks like TMIO core data, but in fact, Renesas private data. Move it to renesas_sdhi.h (probably, it is better to rename it to renesas_sdhi_dma, or squash it into struct renesas_sdhi). I also moved struct renesas_sdhi and host_to_priv() to that header because they are necessary to convert the tmio_mmc_host pointer into the renesas_sdhi pointer.

Allow TMIO and SDHI driver implementations to provide values for max_segs and max_blk_count. A follow-up patch will set these values for Renesas Gen3 SoCs the using an SDHI driver.

Make renesas_sdhi_sys_dmac.c a top-level module file that makes use of library code supplied by renesas_sdhi_core.c This is in order to facilitate adding other variants of SDHI; in particular SDHI using different DMA controllers.

2017-06-20mmc: renesas-sdhi: rename tmio_mmc_dma.c => renesas_sdhi_sys_dmac.cSimon Horman
Rename the source file for DMA for SDHI as a follow-up to attaching DMA code to the SDHI driver rather than the tmio_core driver. The name "renesas" is chosen as the SDHI driver is applicable to a wider range of SoCs than SH-Mobile it seems to be a more appropriate name. However, the SDHI driver source itself, is left as sh_mobile_sdhi to avoid unnecessary churn. The name sys_dmac was chosen to reflect the type of DMA used. Internal symbols have also been renamed to reflect the filename change. A follow-up patch will re-organise the SDHI driver removing the need for renesas_sdhi_get_dma_ops().
