low-power pins can be used while device power management enabled.
Usage
...
&uart0a_rx_p0_0 {
pinmux = <MAX32_PINMUX(0, 0, AF1)>;
low-power-enable;
/* Add low power mode flags, like: */
output-high;
bias-disable;
...
};
...
Default gpio sleep states are defined, user shall update sleep_pins
configuration as per of their needs

This commits added power management states in max32xxx MCUs Common states added in max32xxx.dtsi file and additional ones added in max32655.dtsi Exit-latency-us value set as per of device datasheet spec. The typical value is mentioned in DS is multiplied with 2. For more information please take a look: https://www.analog.com/en/products/max32655.html Signed-off-by: Sadik Ozer <sadik.ozer@analog.com>

Just a small comment. Other than that it looks good to me :) |
This commit add power.c file that provides device goes to low power modes Signed-off-by: Sadik Ozer <sadik.ozer@analog.com>
To simplify usage add dependecy to MAX32_ON_ENTER_CPU_IDLE_HOOK If CONFIG_PM not defined set to to y as current, If CONFIG_PM defined not set it If user set CONFIG_PM not need to disable MAX32_ON_ENTER_CPU_IDLE_HOOK anymore Signed-off-by: Sadik Ozer <sadik.ozer@analog.com>
This commit enables power_mgmt_soc test for MAX32690 board
Low power timer is used as idle timer that will wakeup device
from sleep modes. Lowpower timer clocked with RTC clock which
always on.
RTC can be used as idle clock timer too, in that case below
line need to be added in overlay file
/ {
chosen {
zephyr,cortex-m-idle-timer = &rtc;
};
};
&rtc {
status = okay;
wakeup-source;
};

This commit enables power_mgmt_soc test for MAX32655 boards - max32655evkit - max32655fthr RTC clocked in most low power modes so that this timer is linked with idle timer. By this way device able to wakeup from low power modes. Signed-off-by: Sadik Ozer <sadik.ozer@analog.com>
Enables power management test for MAX78002EVKIT. Signed-off-by: Furkan Akkiz <hasanfurkan.akkiz@analog.com>
Set new default minimum sleep amount for each power state. Users can still update these values depending on their needs. Signed-off-by: Tahsin Mutlugun <Tahsin.Mutlugun@analog.com>
