Functions
void	lampda::power::powergates::init ()
	Called once on system startup.
void	lampda::power::powergates::loop ()
	Called often to refresh the status.
void	lampda::power::powergates::power::blip (const uint32_t timing)
	blip output gate (very short power interruption)
void	lampda::power::powergates::power::cancel_blip ()
	Cancel the current blip if any.
bool	lampda::power::powergates::power::is_bliping ()
	Return true if the output gate is in a blip.
void	lampda::power::powergates::enable_power_gate ()
	enable the power gate. This will first disable the vbus gate, then after a delay enable the power gate.
bool	lampda::power::powergates::is_power_gate_enabled ()
	return true when the gate if enabled (after the delay).
void	lampda::power::powergates::enable_vbus_gate ()
	enable the vbus gate. This will first disable the power gate, then after a delay enable the vbus gate.
void	lampda::power::powergates::enable_vbus_gate_DIRECT ()
	Fast swap only: directly close output gate and enable vbus gate.
bool	lampda::power::powergates::is_vbus_gate_enabled ()
	return true when the gate if enabled (after the delay).
void	lampda::power::powergates::disable_gates ()
	disable immediatly all gates, stop the unlocking processes.
bool	lampda::power::powergates::are_gate_disabled ()
	return true if the gates are disabled.

Detailed Description

Interface layer that handles the safety of the power gaters of the system.

The power gates are the USB gate, to let power pass between the charger and the USB (bidirectional), and the output gate, to send power to the board main output.
