* Paul Walmsley <paul at pwsan.com> [111215 13:05]:
> omap_hwmod_mux() currently only iterates through the dynamic pad list.
> This list currently only consists of pads with the
> OMAP_DEVICE_MUX_REMUX flag set.
> 
> Subsequent patches in this series will cause hwmod mux entries with
> the OMAP_DEVICE_MUX_WAKEUP flag set to be changed dynamically, to
> control hwmod I/O ring wakeup.  For this to work correctly, hwmod mux
> entries with the OMAP_DEVICE_MUX_WAKEUP flag set must also be added to
> the dynamic pad list.  So this patch modifies omap_hwmod_mux_init() to
> do so.
