- void intel_display_power_get(struct drm_i915_private * dev_priv, enum intel_display_power_domain domain);
- i915 device instance
- power domain to reference
This function grabs a power domain reference for domain and ensures that the power domain and all its parents are powered up. Therefore users should only grab a reference to the innermost power domain they need.
Any power domain reference obtained by this function must have a symmetric call to intel_display_power_put to release the reference again.
