[PATCH v6 1/4] Runtime Interpreted Power Sequences

2012-09-12 Thread Alexandre Courbot
Some device drivers (panel backlights especially) need to follow precise sequences for powering on and off, involving gpios, regulators, PWMs with a precise powering order and delays to respect between each steps. These sequences are board-specific, and do not belong to a particular driver - theref
