    gpio: omap: Remove custom PM calls and use cpu_pm instead · b764a586
    Tony Lindgren authored
    For a long time the gpio-omap custom PM calls have been annoying me so
    let's replace them with cpu_pm instead. This will enable GPIO PM for
    deeper idle states on omap4. And we can handle GPIO PM for omap2/3/4
    in the same way.
    
    Note that with this patch we are also slightly changing GPIO PM to be
    less aggressive for omap3 and only will idle GPIO when PER context
    may be lost.
    
    For omap2, we don't need to save context and don't want to remove any
    triggering so let's add a quirk flag for that.
    
    Let's do this all in a single patch to avoid a situation where old
    custom calls still are used with new code.
