Carlos Hernandez <ceh@ti.com> reported that we now have a suspend and
resume regresssion on am3 and am4 compared to the earlier kernels. While
suspend and resume works with v5.8-rc3, we now get errors with rtcwake:
pm33xx pm33xx: PM: Could not transition all powerdomains to target state
...
rtcwake: write error
This is because we now fail to idle the system timer clocks that the
idle code checks and the error gets propagated to the rtcwake.
Turns out there are several issues that need to be fixed:
1. Ignore no-idle and no-reset configured timers for the ti-sysc
interconnect target driver as otherwise it will keep the system timer
clocks enabled
2. Toggle the system timer functional clock for suspend for am3 and am4
(but not for clocksource on am3)
3. Only reconfigure type1 timers in dmtimer_systimer_disable()
4. Use of_machine_is_compatible() instead of of_device_is_compatible()
for checking the SoC type
Fixes:
