    ARM: DT: imx53: fix lvds channel 1 port · 1b134c9c
    Markus Niebel authored
    using LVDS channel 1 on an i.MX53 leads to following error:
    
    imx-ldb 53fa8008.ldb: unable to set di0 parent clock to ldb_di1
    
    This comes from imx_ldb_set_clock with mux = 0. Mux parameter must be "1" for
    reparenting di1 clock to ldb_di1. The value of the mux param comes from device
    tree port settings.
    
    On i.MX5, the internal two-input-multiplexer is used. Due to hardware limitations,
    only one port (port@[0,1]) can be used for each channel (lvds-channel@[0,1],
    respectively)
