I understood what your purpose is...When i checked your patch, i wonder one thing about dwmmc controller. There is also using dwmci_setup_cfg() and it is assigned to cfg->f_min/max with max_clk/min_clk. I think it also needs to take your approach, right? do you have any plan for dwmmc controller? I want to apply at same time..because cfg->f_min/f_max should be used in mmc.c. so It has to consider about all host controller, not only sdhci controller. :) Best Regards, Jaehoon Chung > > Changes in v3: > - Rename arguments of sdhci_setup_cfg function from max_clk/min_clk to > f_max/f_min > > Changes in v2: > - Remove unused index from get uart clock function > - Remove unused index from get sdio clock function > - Introduce common get clock function > > Stefan Herbrechtsmeier (4): > mmc: sdhci: Distinguish between base clock and maximum peripheral > frequency > serial: zynq: Remove unused index from get uart clock function > mmc: zynq: Determine base clock frequency via clock framework > mmc: zynq: Add fdt max-frequency support > > arch/arm/mach-zynq/clk.c | 51 > +++++++++++++++++++++++++++-------- > arch/arm/mach-zynq/include/mach/clk.h | 3 ++- > drivers/mmc/atmel_sdhci.c | 7 +++-- > drivers/mmc/bcm2835_sdhci.c | 3 ++- > drivers/mmc/ftsdc021_sdhci.c | 3 ++- > drivers/mmc/kona_sdhci.c | 3 ++- > drivers/mmc/msm_sdhci.c | 2 ++ > drivers/mmc/mv_sdhci.c | 3 ++- > drivers/mmc/pci_mmc.c | 1 + > drivers/mmc/pic32_sdhci.c | 4 ++- > drivers/mmc/rockchip_sdhci.c | 4 +-- > drivers/mmc/s5p_sdhci.c | 5 ++-- > drivers/mmc/sdhci.c | 34 ++++++++++++----------- > drivers/mmc/spear_sdhci.c | 3 ++- > drivers/mmc/zynq_sdhci.c | 40 ++++++++++++++++++++++++++- > drivers/serial/serial_zynq.c | 2 +- > include/sdhci.h | 13 ++++----- > 17 files changed, 133 insertions(+), 48 deletions(-) > _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
