The STMPE driver would just read/modify/write the system control register on the STMPE1601, meaning it would not properly mask off the PWM block, which remained active if it was on at boot time. This makes sure the blocks are always masked off if they were active on boot, saving some power.

This happened for me during my NO_HZ_FULL testing on isolated CPU, but may happen otherwise as well. When the last htimer of a CPU is cancelled (For example: for NO_HZ_FULL when expires == KTIME_MAX), we do not SHUTDOWN the event device. And because of that we will get interrupted unnecessarily
