    ASoC: arizona: Attach SYSCLK to DSP preloaders · 3577357a
    Charles Keepax authored
    Currently SYSCLK is attached to every compressed DAI as this follows the
    pattern of attaching clocks to the chips inputs and outputs, however, it is
    really the DSP that requires the clock here. As firmware download can be a
    significant part of the path startup time for these devices occasionally it
    would be desirable to download the firmware in advance of the path being
    brought up.
    
    To help facilitate this early firmware loading this patch attaches the
    SYSCLK to the DSP preloader widget. This also saves us adding a new route
    to SYSCLK every time a new compressed DAI is created.
