TOKITA Hiroshi	a511f519b8	drivers: power_domain: gpio_monitor: Fix compilation error The fix `25173f71cd` created `struct pm_device_base` and moved `usage` to it. This has been overlooked so that I fixed it. Signed-off-by: TOKITA Hiroshi <tokita.hiroshi@gmail.com>	9 months ago
Krzysztof Chruściński	25173f71cd	pm: device_runtime: Extend with synchronous runtime PM In many cases suspending or resuming of a device is limited to just a few register writes. Current solution assumes that those operations may be blocking, asynchronous and take a lot of time. Due to this assumption runtime PM API cannot be effectively used from the interrupt context. Zephyr has few driver APIs which can be used from an interrupt context and now use of runtime PM is limited in those cases. Patch introduces a new type of PM device - synchronous PM. If device is specified as capable of synchronous PM operations then device runtime getting and putting is executed in the critical section. In that case, runtime API can be used from an interrupt context. Additionally, this approach reduces RAM needed for PM device (104 -> 20 bytes of RAM on ARM Cortex-M).

Flavio Ceolin	9506720bd8	drivers: power_domain/gpio_monitor: Init priority option Add a Kconfig option to customize initialization priority of gpio monitor power domain. Signed-off-by: Flavio Ceolin <flavio.ceolin@intel.com>	1 year ago
Albert Jakieła	06cfbd4159	drivers: power_domain: Introduce a gpio monitor driver Power rails of some peripherals are controlled externally. This is a case in embedded controllers, where the power of some I2C devices are managed by the main application processor. To ensure that zephyr drivers access the devices where is powered on, introduce a "monitoring" power domain. It works by registering interrupt handler with gpio a pin, so that when power state changes, it will notify relevant drivers. Additionaly add CONFIG_POWER_DOMAIN_INIT_PRIORITY to replace harcoded init priority. Fixes: #51349 Signed-off-by: Albert Jakieła <jakiela@google.com>	2 years ago
