    omap: mux: Add new style pin multiplexing code for omap3 · 15ac7afe
    Tony Lindgren authored
    Initially only for 34xx. This code allows us to:
    
    - Make the code more generic as the omap internal signal
      names can stay the same across omap generations for some
      devices
    
    - Map mux registers to GPIO registers that is needed for
      dynamic muxing of pins during off-idle
    
    - Override bootloader mux values via kernel cmdline using
      omap_mux=some.signa1=0x1234,some.signal2=0x1234
    
    - View and set the mux registers via debugfs if
      CONFIG_DEBUG_FS is enabled
