Cover letter [PATCH v4 0/2] mmc: dw_mmc: exynos: Add HS400 support
Quoted 12 lines · Jaehoon Chung

Hi, Alim.

Quoted 6 lines · Alim Akhtar

This adds HS400 mode support for exynos dw_mmc host controller.

Currently tested on Exynos5800-peach-pi 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

I will test this patch on exynos5/7 board.

What's the result? :-) If it's OK, I'll take DT changes for exynos stuff, I'm not sure about the driver changes though...

Thanks,
Kukjin
