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. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
