[ Upstream commit 4306c047415a227bc72f0e7ba9bde1ccdac10435 ]
STM32MP15xx RM0436 Rev 6 section 46.3 System timer generator (STGEN) states " Arm recommends that the system counter is in an always-on power domain. This is not supported in the current implementation, therefore STGEN should be saved and restored before Standby mode entry, and restored at Standby exit by secure software. ... " Instead of piling up workarounds in the firmware which is difficult to update, add "arm,no-tick-in-suspend" DT property into the timer node to indicate the timer is stopped in suspend, and let the kernel fix the timer up.
