Re: [PATCHv10 3/5] ARM: dts: exynos: unuse the slot-node and deprecate the supports-highspeed for dw-mmc

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi, Kukjin.

Socfpga and Rockchip were queued into each SoC tree.
I want to know whether this patch is queued or not into Samsung-Soc tree.
Do you have any other plan for this patch?

Best Regards,
Jaehoon Chung
