2023-02-02[DO NOT MERGE] Usb Gadget HAL: modify monitorfs behaviorRay Chi
Currently, monitorffs will pull up gadget when the ffs endpoints are ready. When the device change the data role from peripheral to host, the pullup behavior will still occur. It will cause the host mode and peripheral mode start in the same time. This patch will check typec and USB gadget state before pulling up gadget.

2021-08-25libpixelusb: Cancel pending timer when port is coldBadhri Jagan Sridharan
Pending timer would post events to the timerfd when the timer expires. This would prevent system from suspending as the monitor thread might be in condition variable as the port might already be cold. To prevent this: 1. Cancel timer when woken up due to cold port. 2. Make the monitor wait in the epollfd instead of waiting in the cv. This makes sure that the monitor thread is not sleeping when there are pending events to be processed which in turn blocks suspend. Bug: 197529577 Test: Emulate port status to hot; adb shell "echo 35001 > dev/thermal/tz-by-name/usb_pwr_therm2/emul_temp"; adb shell "echo 31000 > dev/thermal/tz-by-name/usb_pwr_therm/emul_temp"; adb shell "echo 21000 > dev/thermal/tz-by-name/qi_therm/emul_temp"; Emulate cold right after the timer wakeup; adb shell "echo 10000 > dev/thermal/tz-by-name/usb_pwr_therm2/emul_temp"; /d/wakeup_sources does not list timerfd7:android.hardwar as active wakeup source.

2021-08-17libpixelusb: Do not write into eventfd when temperature is not monitoredBadhri Jagan Sridharan
b9f33ac34dbe2a1505dcea7f24004c42ea2a8a70 ("thermal: send notification after callback registered") makes thermal hal to send out a callback, right after the registration, even when there is no change in the throttling status. This causes a pending event to be posted to the eventfd eventhough monitorThread is waiting in the cv_ for the throttling status to be hot. This prevents system from suspending as the pending event in evenfd would never be cleared. To prevent this check for monitorTemperature and bail out if needed.

2021-07-21libpixelusb: Add logic to gather termperature stats for overheatBadhri Jagan Sridharan
Added UsbPortOverheat which subscribes to thermal hal's notification callback for monitoring usb port thermal zone's throttling status. When throttled, the relevant thermal zones are queried for temperature and the maximum temperature is stored. The maximum temperature reached during the throttling window is then reported through suez. Bug: 193615568 Test: adb shell "echo 35001 > dev/thermal/tz-by-name/usb_pwr_therm2/emul_temp"; adb shell "echo 31000 > dev/thermal/tz-by-name/usb_pwr_therm/emul_temp"; adb shell "echo 21000 > dev/thermal/tz-by-name/qi_therm/emul_temp"; wait for few seconds, adb shell "echo 10000 > dev/thermal/tz-by-name/usb_pwr_therm2/emul_temp"; Change-Id: I2b3ee4197205f07bf5b3763176233e0fc89519c1

There is new requirement to check the physical sim card. It need oem functions to get information from subsystems. The bootmode in provisioning station is "ffbm-01". Therefore, to enable oem functions in new bootmode is necessary. In addition, the feature between "ffbm-00" and "ffbm-01" should be the same, so it need to be enabled on two bootmodes.
