Detailed Description

Regulator driver for a rail switched by a GPIO, as a load switch.

The enable level is set by _active_high, whatever the GPIO flags say, as the Linux regulator-fixed binding does with enable-active-high.

PBL_REGULATOR_FIXED_DEFINE(s_vlcd, "vlcd", PBL_GPIO(&dt_gpio1, 29, 0), false, 0, false);

struct pbl_regulator_fixed

Fixed regulator.

Data Fields
bool	active_high	Enabled at a high level.
struct pbl_gpio	enable	Enable GPIO.
struct pbl_regulator	reg	Regulator.
uint32_t	startup_delay_us	Time from enabling until the rail is up, in microseconds.

Macro Definition Documentation

PBL_REGULATOR_FIXED_DEFINE

#define PBL_REGULATOR_FIXED_DEFINE	(		sym,
			_name,
			_enable,
			_active_high,
			_startup_delay_us,
			_always_on
	)

Value:

  PBL_REGULATOR_STATE_DEFINE(sym);                                                             \
  PBL_DEVICE_INSTANCE(sym, struct pbl_regulator_fixed, struct pbl_regulator, reg) {            \
    .reg = PBL_REGULATOR_INIT(sym, _name, nullptr, &pbl_regulator_fixed_ops, _always_on),      \
    .enable = _enable, .active_high = (_active_high), .startup_delay_us = (_startup_delay_us), \
  }

Define a fixed regulator.

Parameters

sym	Symbol of the regulator.
_name	Name.
_enable	Enable GPIO, from PBL_GPIO().
_active_high	Enabled at a high level.
_startup_delay_us	Time from enabling until the rail is up, in microseconds.
_always_on	Switched on at init and never off.
