I think what Krzysztof was asking was just if he can simply pick up this patch alone, as it does not require any of the previous changes. Same is true for the Rockchip patches I guess, so we could just take them individually into samsung/rockchip dts branches.

Yes, I wanted to get exactly this information. I couldn't find it in cover letter.

I couldn't find it in > cover letter. In drivers/mmc/core/host.c, there already is "max-frequency" property. It's same functionality with "clock-freq-min-max". Minimum clock value can be fixed to 100K. because MMC core will check clock value from 400K to 100K. But max-frequency can be difference. If we can use "max-frequency" property, we don't need to use "clock-freq-min-max" property anymore. I will resend the deprecated property instead of removing "clock-freq-min-max". If you want to pick this, it's possible to pick. Then i will resend the patches without dt patches.

In drivers/mmc/core/host.c, there is "max-frequency" property. It should be same behavior. So Use the "max-frequency" instead of "clock-freq-min-max".
