Add PM action for MCUX LPC driver Signed-off-by: Mahesh Mahadevan <[email protected]>
Add power action callback handlers to the driver. Signed-off-by: Mahesh Mahadevan <[email protected]>
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 <[email protected]>
This is required to re-initialize the peripherals on exit from Power Mode 3. Signed-off-by: Mahesh Mahadevan <[email protected]>
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 <[email protected]>
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 <[email protected]>
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 <[email protected]>
Update the clock init code to gate off unused clocks. Signed-off-by: Mahesh Mahadevan <[email protected]>
Power Domains are used to re-enable peripherals when exit Power Mode 3 (Standby). Signed-off-by: Mahesh Mahadevan <[email protected]>
Provide an API for other drivers to fire GPIO callbacks Signed-off-by: Mahesh Mahadevan <[email protected]>
Call the API provided to fire a GPIO interrupt if registered on wakeup from PM Mode 3. Signed-off-by: Mahesh Mahadevan <[email protected]>
This is used as wakeup source to wakeup from Power Modes 3 and 4. Signed-off-by: Mahesh Mahadevan <[email protected]>
Enable PM mode 3 on NXP FRDM_RW612 and RD_RW612 boards. Signed-off-by: Mahesh Mahadevan <[email protected]>
