2016-10-24qpnp-fg-gen3: Fix storing nominal capacity to actual capacitySubbaraman Narayanamurthy
Currently, nominal capacity is stored back to the actual capacity only when the actual capacity is non-zero. However, that can be true when the battery is inserted for the first time. This makes the actual capacity to be stored only when a capacity learning cycle completes. Other algorithms like to use actual capacity before that. Fix it.

2016-10-24smb-lib: update displaying battery overvoltage in health propertySubbaraman Narayanamurthy
Currently, smb2 charger is configured to not end the charging cycle when battery overvoltage occurs. However, when the battery overvoltage status is read, it will be displayed through health property. Improve this by reading the battery voltage and check whether it is within 40mV headroom above float voltage. If it is above that threshold then continue with displaying overvoltage status.

The adc notification callback assumes that it will end up selecting the correct state. However, if the parameters are outside the expected values, the code could end up dereferencing a null pointer. Fix this by returning before that pointer is dereferenced. Change-Id: I42642b475a1032c3a7395336381f3bd6c1396dde Signed-off-by: Abhijeet Dharmapurikar <adharmap@codeaurora.org>

2016-10-19qpnp-smb2: implement PE_START propertyAbhijeet Dharmapurikar
The policy engine needs to be informed that its time to start its activities when APSD results are available and/or PD_ALLOWED is decided. USB type property shouldn't change after that. Since HVDCP_TIMEOUT_VOTER is the last one to cast its allow vote in the sequence, use it to reflect the PE_START property. While at it since PE_START property is returned assuming an atomic context, the read of PD_ALLOWED could be moved to its sleepable variants. This aids in keeping the policy engine code simple and also assures race free code.

2016-10-17smb-lib: rerun apsd if not pdAbhijeet Dharmapurikar
If an HVDCP charger is detected and it does not support PD, that means it is likely a legacy QC2 or QC3 charger. Rerun APSD when PD sets us to be inactive. For cases when pd is not allowed, PD won't set inactive status. For such cases use the hvdcp_timeout interrupt to rerun APSD.

2016-10-17smb-lib: support separate current settings from usb and pdAbhijeet Dharmapurikar
Add support to set current limits from usb and pd. 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.

2016-10-17smb-lib: provide insertion removal functionsAbhijeet Dharmapurikar
The current driver votes and unvotes for removal/insertion at two interrupt handlers, debounce done and the type C detach. 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.

2016-10-17qpnp-smb2: handle shorted vbus and cc lines and legacy cablesAbhijeet Dharmapurikar
There could be cables where vbus and cc lines are shorted or connected using a small resistor. 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.

2016-10-17qpnp-smb2: support exiting sink based on ccAbhijeet Dharmapurikar
While PD is under hard reset and the device is in sink mode, it shouldn't leave sink mode because VBUS goes away. 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.

2016-10-17qcom-charger: Allow PD for hvdcpAbhijeet Dharmapurikar
Currently the code prevents pd if an hvdcp is detected. 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.
