* | power: qpnp-fg-gen3: Improve ESR accuracy at cold temperature with QnovoSubbaraman Narayanamurthy2017-12-20
|/ | | | | | | | | | | | | | When the battery is in cold temperature for a certain amount of time and device is charged with Qnovo enabled charging, ESR pulse will fire less frequently. This along with ESR pulses not getting qualified can cause the ESR to be less accurate. To improve ESR accuracy, add change to apply relaxed filter coefficients once the battery temperature starts ramping up after hitting a lower threshold of say 6 C after charging begins.

* | | smb-lib: allow hvdcp if pd is disabledAbhijeet Dharmapurikar2017-11-20
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently when pd is disabled, we do not allow hvdcp. To fix that once hvdcp timeout happens and if pd is disabled, force a pd_active = 0. This will cause us to run legacy workaround and rerun apsd if the charger was detected as hvdcp. Importantly, once legacy bit workaround is run, wait 400mS for typeC to debounce. Currently we wait for 100mS only and that causes a removal detection since the CC lines are not settled within 100mS. Also it may take up to 650mS for the vbus to drop once CC lines are floated during the workaround. The current wait is just 500mS, bump it up to a 1 second.

* | power: qpnp-fg-gen3: update battery profile based on Rconn configurationSubbaraman Narayanamurthy2017-11-14
|/ | | | | | | | | | | | | | | | | | | | Currently, Rconn is configured once in fg_hw_init() if it is not configured already. However, if the driver loads the profile later, it will overwrite the Rconn value configured during fg_hw_init. To fix this problem, configure Rconn after handling battery profile loading. Usually the Rconn configuration is setup differently from what the profile has for it. We check if the profile in SRAM is bit to bit matching with the profile in device tree. We may come across a mismatch for Rconn configuration and conclude that the profile isn't matching. Fix this by initializing the Rconn configuration in the profile read from device tree to the value read from SRAM.

* | power: qpnp_smb2: configure to extend DRP.DFP time in try.SNKHarry Yang2017-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When both sides are doing DRP and the other side applies Rd near the end of PMIC DFP cycle, sometimes, PMIC does not lock on into AttachedWait.SRC and transitions back into Unattached.SNK. If a resistance ranging (5.1k,300k) pulldown is applied and then 5.1kohms pulldown is applied, then it takes 10-20ms to detect 5.1kohms. Before this, if DRP.DFP time expires, then PMI transitions to UFP mode to avoid extending DRP cycle time. Fix it by extending DFP time. Note the total DRP time should still be within max limit (100ms). Change-Id: I1dd180229bc771542b4f6ca7850aa457478ae5cd Signed-off-by: Harry Yang <harryy@codeaurora.org>

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Try.SNK allows a DRP that has a policy based preference to be a Sink when connecting to another DRP to effect a transition from a destined Source role to the Sink role. This is a Software implementation for PMI8998. Exiting from AttachWait.SRC State, a DRP that strongly prefers the Sink role may optionally transition to Try.SNK instead of Attached.SRC. When in the Try.SNK state, the port is querying to determine if the port partner supports the Source role. The port shall then transition to Attached.SNK when the SNK.Rp state is detected for at least tTryCCDebounce and VBUS is detected Alternatively, the port shall transition to TryWait.SRC if SNK.Rp state is not detected tTryCCDebounce. The port shall transition to Attached.SRC when SRC.Rd state is detected on exactly one of the CC pins. The port shall transition to Unattached.SNK after tDRPTry if neither of the CC1 or CC2 pins is in the SRC.Rd state.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, charge_counter is based off CC_SOC_SW which is based off coulomb counter. However, there could be some accumulation of error due to inaccuracy in ADC over time. This can potentially affect the accuracy of charge_counter. To overcome this, prime CC_SOC_SW during discharging based off battery SOC and to a full value during charge termination. While at it, expose the charge_counter_shadow property based off battery SOC for comparison.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Delta battery SOC interrupt can fire during boot just after registering the interrupts before disabling it through vote() on delta_bsoc_irq_en_votable during driver probe. When this happens, from the delta_bsoc interrupt handler, an attempt to disable the interrupt can be made by fg_charge_full_update() if charge_done is not set. This will in turn acquire the mutex lock of votable while trying to do disable_irq() which needs synchronization. Prevent this situation by using disable_irq_nosync() when disabling the interrupts from votable callbacks.

However in that time window, if Qnovo is disabled for some reason then ESR extraction control will be kept disabled unexpectedly. Fix this by protecting both the paths using a mutex lock as well as checking for qnovo enable status before disabling ESR extraction control after measuring ESR.
