🦋 Members 🦋

  • node — pointer to the device tree node of the PM domain provider. your provider's literal home address in the DT 🌳
  • xlate — provider-specific xlate callback that maps a set of specifier cells into a PM domain. bestie this is the translator — it takes those specifier cells and turns them into an actual PM domain, slay 🧚
  • data — context pointer to be passed into the xlate callback. the little bag of snacks xlate gets handed when it gets called 🍓
