Dear Nordic,
As per power management, could you please suggest any thoughts for following:
We have two ICs on the board connected to nRF52840: 6-DOF sensor (over SPI) and flash mem (over QSPI). Both of them are powered from one external LDO regulator controlled by GPIO output, and there is a 'regulator' node has been defined for it.
1. 'nordic,qspi-nor' device node model doesn't include 'vin-supply' parameter, how we could connect it to regulator to take automatic control over QSPI flash power?
2. When accessing 6-DOF sensor, we need to take manual control over it's powering, and - when it is not in work - it should be disabled completely, including SPI lines. For now, when we turn off the regulator manually, the SPI lines stays active and give parasitic supply to the sensor and increase overall consumption. What approach is preferred to implement here? Something like that? (https://github.com/zephyrproject-rtos/zephyr/blob/main/samples/subsys/pm/device_pm/src/main.c)
