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

 



Add LCDIF scanout engine and DSIM bridge nodes for i.MX8M Nano.
This makes the DSI display pipeline available on this SoC.

V2: - Drop the address-cells/size-cells from DSIM node
    - CC Alexander, Jagan
    - Bundle the MX8MM,N,P patches together in one series
