    omap_hsmmc: Allow for a shared VccQ · e0eb2424
    Adrian Hunter authored
    EMMC can have two voltage supplies, Vcc and VccQ
    which are implemented in the code as consumer
    supplies vmmc and vmmc_aux.
    
    If the regulator that supplies vmmc_aux is shared
    with other consumers, then sending it to sleep
    will disrupt those consumers.  However, the
    TWL4030-family regulators may have OFF remapped
    to SLEEP, in which case 'regulator_disable()'
    will put the regulator to sleep only when all
    consumers are disabled - which is the desired
    behaviour.
    
    This patch adds a platform data field to allow
    that option.
