29 Flexible power sequence configurations:
30 --------------------------------------
31 The Flexible Power Sequencer (FPS) allows each regulator to power up under
32 hardware or software control. Additionally, each regulator can power on
33 independently or among a group of other regulators with an adjustable power-up
34 and power-down delays (sequencing). GPIO1, GPIO2, and GPIO3 can be programmed
44 eight sequencing events on different time periods called slots. The time
46 Each regulator, GPIO1, GPIO2, GPIO3, and 32KHz clock has a flexible power
48 a flexible power sequencer timer or a software bit. When a FPS source of
50 power sequencer, the power up and power down delays can be specified in
51 the regulators, GPIOs and clocks flexible power sequencer configuration
60 Global Low Power Mode (GLPM): In this state, regulators are set in
61 low power mode at the sequencing event.
63 The configuration parameters of FPS is provided through sub-node "fps"
67 The FPS configurations like FPS source, power up and power down slots for
69 configuration nodes which is explained in respective sub-system DT
72 There is need for different FPS configuration parameters based on system
74 power off (shutdown).
