8 Dynamic Audio Power Management (DAPM) is designed to allow portable
13 DAPM is also completely transparent to all user space applications as
15 recompiling are required for user space applications. DAPM makes power
19 DAPM is based on two basic elements, called widgets and routes:
26 All DAPM power switching decisions are made automatically by consulting an

41 DAPM power domains
44 There are 4 power domains within DAPM:
72 DAPM Widgets
75 Audio DAPM widgets fall into a number of types:
142 (Widgets are defined in include/sound/soc-dapm.h)
145 There are convenience macros defined in soc-dapm.h that can be used to quickly
146 build a list of widgets of the codecs and machines DAPM widgets.
239 The codec bias power domain has no widgets and is handled by the codec DAPM
256 Registering DAPM controls
259 In many cases the DAPM widgets are implemented statically in a ``static

359 This allows the DAPM to power on and off pins that are connected (and in use)
374 Endpoints are added to the DAPM graph so that their usage can be determined in
379 DAPM Widget Events
