[PATCHv6 2/2] ARM: dts: unuse the slot-node and deprecated supports-highspeed for dw-mmc.

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

 



dw-mmc controller can support multiple slots.
But, there are no use-cases anywhere. So we don't need to support the
slot-node for dw-mmc controller.
And "supports-highspeed" property in dw-mmc is deprecated.
"supports-highspeed" property can be replaced to "cap-sd/mmc-highspeed".
