[PATCH v3 8/9] ARM: sun8i: Add PRCM clock and reset controller nodes to the DTSI

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

 



With sun8i PRCM support available, we can add the PRCM clock and
reset controller nodes to the DTSI. Also update R_UART's clock
phandle and add it's reset control phandle.
