Kind regards Uffe
Hi! The ARTPEC-8 SoC has a DWMMC controller that is compatible with the Exynos 7 version v2.70a. The main differences from Exynos 7 is that it does not support HS400 and has an extended data read timeout. To run this controller we need to add compatibility for ARTPEC-8, because we need to separate the configuration of the TMOUT register from the non ARTPEC-8 versions. This patchset is dependent on 2 changes that has been added to the mmc git next branch, but has not yet been merged to mainline: Patch 2 of this patchset depends on commit 0e6f2c4c2072b ("mmc: dw_mmc: add common capabilities to replace caps"). Patch 3 of this patchset depends on commit d5bc33487eab3 ("mmc: dw_mmc: Allow lower TMOUT value than maximum"). Kind regards Mårten Lindahl Changes in v2: - Change compatible string vendor prefix - Removed unnecessary comment - Change 1<<0 to BIT(0) Changes in v3: - Add callback for implementation specific control of data timeout - Add callback for implementation specific read of cycle count for data timeout. - Move definition of DW_MMC_QUIRK_EXTENDED_TMOUT from patch 3/4 to patch 4/4. Changes in v4: - Add Reviewed-by and Acked-by tags from Krzysztof Kozlowski Changes in v5: - Remove redundant '0x' prefix from debug message - Add Acked-by tag by Rob Herring Mårten Lindahl (4): dt-bindings: mmc: exynos-dw-mshc: Add support for ARTPEC-8 mmc: dw_mmc-exynos: Add support for ARTPEC-8 mmc: dw_mmc: Add driver callbacks for data read timeout mmc: dw_mmc: Do not wait for DTO in case of error .../bindings/mmc/exynos-dw-mshc.txt | 2 + drivers/mmc/host/dw_mmc-exynos.c | 101 ++++++++++++++++-- drivers/mmc/host/dw_mmc.c | 21 +++- drivers/mmc/host/dw_mmc.h | 10 ++ 4 files changed, 122 insertions(+), 12 deletions(-)
