pogo_transport: Fix HES mistriggered cases
There are two cases for the HES mistriggered events.
Case #1: H1S state 0 reported during the acc detection
[ 4164.863428] EV:H1S state 1
[ 4164.863633] H1S: accessory detection 0, mfg 0
[ 4164.863637] QUEUE EVENT 3
[ 4164.864567] POGO ACC IRQ triggered
[ 4164.864665] Pogo acc threaded irq running, acc_detect 0
[ 4164.864768] POGO ACC IRQ triggered
[ 4164.864816] Pogo acc threaded irq running, acc_detect 0
[ 4164.864961] POGO ACC IRQ triggered
[ 4164.864999] Pogo acc threaded irq running, acc_detect 1
[ 4164.865002] QUEUE EVENT 4
[ 4164.865082] EV:H1S state 0
[ 4164.865086] EV:ACC_GPIO_ACTIVE
[ 4164.865094] pending state change STANDBY -> STANDBY_ACC_DEBOUNCED @ 20 ms
[ 4164.867384] POGO ACC IRQ triggered
[ 4164.867434] Pogo acc threaded irq running, acc_detect 0
[ 4164.888241] [ 5805] state change STANDBY -> STANDBY_ACC_DEBOUNCED [delayed 20 ms] []
Case #2: H1S stays at 1 during the acc detection
[ 861.585046] EV:H1S state 1
[ 861.586088] POGO ACC IRQ triggered
[ 861.586189] Pogo acc threaded irq running, acc_detect 0
[ 861.586318] POGO ACC IRQ triggered
[ 861.586358] Pogo acc threaded irq running, acc_detect 0
[ 861.586391] POGO ACC IRQ triggered
[ 861.586430] Pogo acc threaded irq running, acc_detect 1
[ 861.586433] QUEUE EVENT 4
[ 861.586571] EV:ACC_GPIO_ACTIVE
[ 861.586584] pending state change STANDBY -> STANDBY_ACC_DEBOUNCED @ 20 ms
[ 861.588522] POGO ACC IRQ triggered
[ 861.588672] Pogo acc threaded irq running, acc_detect 0
[ 861.609863] [ 1063] state change STANDBY -> STANDBY_ACC_DEBOUNCED [delayed 20 ms] []
[ 865.464562] POGO ACC IRQ triggered
[ 865.464805] Pogo acc threaded irq running, acc_detect 1
[ 865.464818] QUEUE EVENT 4
[ 865.465221] EV:ACC_GPIO_ACTIVE
[ 865.465232] pending state change STANDBY_ACC_DEBOUNCED -> STANDBY_ACC_DEBOUNCED @ 20 ms
[ 865.471192] POGO ACC IRQ triggered
[ 865.471393] Pogo acc threaded irq running, acc_detect 0
[ 865.486007] [ 1072] state change STANDBY_ACC_DEBOUNCED -> STANDBY_ACC_DEBOUNCED [delayed 20 ms] []
[ 865.602370] POGO IRQ triggered
[ 865.602636] Pogo threaded irq running, pogo_gpio 0
For Case #1, run acc detaching process when the ACC_GPIO_ACTIVE event is
triggered.
For Case #2, disable acc regulator when the POGO IRQ is triggered (GPIO
active) and continue to normal dock detection.
