[PATCH v3 0/2] earlycon: Let users set the clock frequency

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

 



Some platforms, namely AMD Picasso, use non standard uart clocks (48M),
witch makes it impossible to use with earlycon.
    
Let the user select its own frequency.
