2016-01-28soc/braswell/acpi/DPTF: Write TCHG state on AC connect.Jenny TC
DPTF should update the charger cooling device state during boot time and every 3 seconds after boot. But 3 seconds polling doesn't seems to be working with current version of DPTF. This impacts charging since DPTF writes states 4 when charger is not connected at boot time. On connecting the charger, DPTF doesn't write 0 to enable charging. This issue is addressed by calling the PPPC function to read cooling device state and passing the value to SPPC to set cooling device state. This doesn't compromise safety since DPTF can override this value later based on the platform thermal condition. Also this provides additional safety measure in the unlikely event that DPTF crashes and is not re-spawned by OS. With this patch even after DPTF crashes, if the power adapter is plugged it would still allow the system to charge correctly.
