Add PM action for MCUX LPC driver Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>
Add power action callback handlers to the driver. Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>
This maps to Power Mode 3 in the SoC. Add RTC node that is used to wakeup from this mode. Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>
This is required to re-initialize the peripherals on exit from Power Mode 3. Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>
This clock is used for certain peripherals such as RTC. On certain RW612 boards such as rd_rw612_bga, XTAL32K and ENET share pins. Add code to check if ENET and XTAL32 are enabled at the same time. Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>
Since the clock source when running in PM mode 3 is the slower 1KHx clock, we adjust the SYS_CLOCK_TICKS_PER_SEC value to get better accuracy. Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>
This maps to Zephyr power state Standby. In this power state the OS Timer cannot be used as a wakeup source as it will be powered off. Hence the counter is enabled and RTC is used to keep track of system ticks and wakeup the system. Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>
Update the clock init code to gate off unused clocks. Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>
Power Domains are used to re-enable peripherals when exit Power Mode 3 (Standby). Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>

Provide an API for other drivers to fire GPIO callbacks Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>
Call the API provided to fire a GPIO interrupt if registered on wakeup from PM Mode 3. Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>
This is used as wakeup source to wakeup from Power Modes 3 and 4. Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>
Enable PM mode 3 on NXP FRDM_RW612 and RD_RW612 boards. Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>
This driver triggers the TURN_ON and TURN_OFF actions for certain power states. These power states are specified via device tree. Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>
1. The sys_clock_idle_exit function could be invoked multiple times. Hence add code so that is counter is stopped and the OS Timer is initialized once. 2. Reset the OS Timer when exiting low power modes where the OS Timer loses its state 3. Improve the cycles conversion algorithm. Round to the nearest microsecond when converting from ticks to microsecond rather than always rounding up to the next highest value. Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>
