There is a known issue in EC event handling. This patchset tries to handle noirq stage EC event polling to fix this known issue.
In the very early version, the EC event polling mechanism is implemented by a kernel thread to poll EC events. Now the mechanism is implemented by a timer ticked in noirq stage to poll EC GPEs. In this newest timer version, timer running period is shortened and thus is safer for s2idle mode. After adding such a mechanism, we can try to handle EC events earlier after resume, this may be able to solve some driver order issues.
