Ensure that the limit from the pd is only enforced when pd is active and that the limit from usb is enforced only when pd is inactive. There is one situation when the input needs to be suspended as per the usb driver's request when pd sets system_suspend_supported. For that allow the usb voter to set that low current value to suspend. Also ensure that the pd and usb votes are nullified when source is removed. In addition, the return the individual valid votes from usb and pd when their current_max are read.

The recommendation from hw teams is to use debounce done for both insertion and removal. Update the code. While at it, provide clean functions to vote and unvote for four situations a typec cable insertion a typec cable removal a source insertion a source removal Note that this allows us to cleanly handle PD hard resets where the typec connection remains intact but the source (or vbus) related state needs to be reset. This also helps us in cleanly handling power sole swaps where the source plugged and removed functions handle vbus related states while typec functions handle the typec related states.

* | | | | | qpnp-smb2: handle shorted vbus and cc lines and legacy cablesAbhijeet Dharmapurikar2016-10-17

Raising VBUS to higher values could cause CC line to get damaged. CC line cannot tolerate a voltage higher than 6V. So if such a cable is seen, prevent pd stack from running so there is no opportunity to increase vbus by selecting a higher voltage profile. Also disable HVDP too. Also, prevent PD_ALLOWED if a legacy cable is seen - the spec mentions that if VBUS is seen along with CC, the adapter is not pd capable.

Instead it should stay in sink mode while hard reset is being conducted and exit sink mode only if CC gets detached. Configure the exit state when hard reset is in progress. Also while hard reset is in progress disable APSD else a APSD could run and disturb SDP communication after VBUS recovers in hard reset procedure.

* | | | | | qcom-charger: Allow PD for hvdcpAbhijeet Dharmapurikar2016-10-17

We want to change that in that we want to prevent pd only while hvdcp detection is in progress. Once completed, we need to enable pd even if an hvdcp is detected. Enabling PD even for hvdcp allows us to detect a QC 4.0 which communicates over PD. Currently we model the pd_allowed votable as an enable votable i.e. if any one of the voters enable it, pd_allowed gets enabled. Change that to a disable votable named pd_disallowed_votable, which gets disabled when CC is detached, and hvdcp2.0 detection is not yet completed.

However, because of missing battery SRAM access over IMA can fail leading to errors. Eventually, the errors will go away when the battery is inserted again. However, if the user tries to access SRAM registers or bms power supply properties, it can cause further errors flooding logs. Handle this gracefully by returning an error upon battery missing is detected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Open circuit voltage and predicted battery voltage are read from 16 bits. However, the real value is present only in 15 bits. Mask the bit 16 to get the proper readings.

| * | | | | power: qpnp-fg-gen3: add capacity learning featureSubbaraman Narayanamurthy2016-10-10

Capacity learning is a feature which uses the hardware autonomous coulomb counter to determine the actual battery capacity against the advertised full capacity. This will be useful to determine how much degradation has happened to the battery. Capacity learning algorithm will start based on some pre-set conditions like start SOC, battery temperature and ends when the charging cycle is complete. Actual capacity will be exposed through charge_full property. Change-Id: I89cc14d213b0de10bc8d052dd76e1468fe9c30e5 Signed-off-by: Subbaraman Narayanamurthy <subbaram@codeaurora.org>

Fix this by regulating the OTG boost start and altering PFM threshold in software.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a module parameter "fg_restart" to restart the fuel gauge without loading the battery profile.
