I tested this series on linux-next, on Exynos5800-peach-pi board, and HS400 seems to be working fine. I can see the card getting detected as HS400, and then i ran iozone as well. The iozone numbers are also as required. On peach-pit board too, the HS200 mode seems to be working good. What are the observations you saw on your board ? > > Best Regards, > Jaehoon Chung > > On 01/29/2015 11:41 AM, Alim Akhtar wrote: >> This adds HS400 mode support for exynos dw_mmc host controller. >> >> Currently tested on Exynos5800-peach-pi and Exyons7 platform for HS400 mode. >> Tested HS200 mode with this series applied, HS200 still works. >> >> Appreciate testing on other exynos5/7 platform which supports emmc5.0 >> >> Changes in V5: >> * Enable HS400 on Exynos5800-peach-pi boards >> * Addressed other review comments from Jaehoon Chung >> >> Changes in V4: >> * drop the idea of changing existing binding for ciu_div as per [1] >> * addressed comments from Jaehoon Chung [2] >> >> [1] http://www.spinics.net/lists/linux-samsung-soc/msg40923.html >> [2] http://www.spinics.net/lists/devicetree/msg64373.html >> >> Changes in V3: >> rebased on ulf's next (commit: 607b448 mmc: core: Make tuning block patterns static) >> >> Seungwon Jeon (2): >> mmc: dw_mmc: exynos: Support eMMC's HS400 mode >> ARM: dts: Add HS400 support for exynos5420 and exynos5800 >> >> .../devicetree/bindings/mmc/exynos-dw-mshc.txt | 7 + >> arch/arm/boot/dts/exynos5420-peach-pit.dts | 4 +- >> arch/arm/boot/dts/exynos5420-pinctrl.dtsi | 7 + >> arch/arm/boot/dts/exynos5420-smdk5420.dts | 4 +- >> arch/arm/boot/dts/exynos5800-peach-pi.dts | 7 +- >> drivers/mmc/host/dw_mmc-exynos.c | 185 ++++++++++++++++---- >> drivers/mmc/host/dw_mmc-exynos.h | 19 +- >> drivers/mmc/host/dw_mmc.c | 16 +- >> drivers/mmc/host/dw_mmc.h | 2 + >> 9 files changed, 213 insertions(+), 38 deletions(-) >> > > -- > To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- Best Regards Vivek Gautam Samsung R&D Institute, Bangalore India -- 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
