This series implements most of what's required to have tuning work on rk3288. A lot of this is inspired by the exynos tuning code, but generalized to work for any number of phases. At one point I realized that the tuning is not rockchip specific so I changed it to work for any dw_mmc device. Rockchip specific stuff: "rk3288: Add drive/sample clocks" needs "ARM: dts: rockchip: set dw_mmc max-freq 150Mhz" to apply cleanly. So this series is based on heiko's github repository: https://github.com/mmind/linux-rockchip/tree/wip/v3.20-armsoc/dts The missing DTO interrupt is still a problem in DWMMC, at least on rockchip. So if you want to test this you might want to grab "[PATCH v3] mmc: dw_mmc: add quirk for broken data transfer over scheme" and my change in the replies there. Warning: it still causes problems on some cards. And of course one would have to enable the high speed functionality, something like this would suffice: https://chromium-review.googlesource.com/#/c/227199/34/arch/arm/boot/dts/rk3288-veyron.dtsi Alexandru M Stan (3): mmc: dw_mmc: dt-binding: Add tuning related things mmc: dw_mmc: Generic MMC tuning with the clock phase framework ARM: dts: rk3288: Add drive/sample clocks for dw_mmc devices .../devicetree/bindings/mmc/synopsys-dw-mshc.txt | 14 +- arch/arm/boot/dts/rk3288.dtsi | 20 ++- drivers/mmc/host/dw_mmc.c | 189 +++++++++++++++++++++ include/linux/mmc/dw_mmc.h | 3 + 4 files changed, 214 insertions(+), 12 deletions(-) -- 2.2.0.rc0.207.ga3a616c -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
