[PATCH 10/10] ARM: dts: r7s9210-rza2mevb: Add USB host support

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

 



Enable USB Host support for both the Type-C connector on the CPU board
and the Type-A plug on the sub board.

Both boards are also capable of USB Device operation as well after the
appropriate Device Tree modifications.
