* | | | power: qpnp-fg-gen3: update SOC masking algorithmSubbaraman Narayanamurthy2017-09-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, FULL_SOC and MONOTONIC_SOC registers are updated multiple times when the recharge SOC threshold is close enough to trigger the recharging frequently. This was leading to a SOC fluctuation when SOC masking algorithm is enabled. Rearrange charge_full_update used in SOC masking algorithm such that FULL_SOC and MONOTONIC_SOC registers are updated just once when the charge_full flag is cleared. Also, when the device is rebooted/shutdown and if charge_full flag is set, write to FULL_SOC with battery_soc and a full value to MONOTONIC_SOC registers. This helps to maintain the same SOC across a device reboot. Change-Id: I95afa90f27e4c0f948f301ff8d6a1f84ae422ef0 Signed-off-by: Subbaraman Narayanamurthy <subbaram@codeaurora.org>

* | | | power: qpnp-fg-gen3: apply SOC linearization based on user inputSubbaraman Narayanamurthy2017-08-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, SOC linearization is done when SOC masking feature is enabled to spread out the drop in SOC across a wider range and for better user experience. Make this configurable through a DT property "qcom,linearize-soc" so that the user can enable it as and when required.

* | | | power: qpnp-fg-gen3: make CHARGE_FULL property writable by userSubbaraman Narayanamurthy2017-08-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CHARGE_FULL property indicates the learnt capacity of the battery from the last capacity learning cycle. However, in some rare cases, if the learnt capacity is having an unexpected value, it requires a reset to a good value which is not possible for an user who cannot reinsert a battery or do an explicit write to FG SRAM. Allowing CHARGE_FULL to be writable helps this. Change-Id: I05aa8392f103685f8fc1ba5a3780122150be0ee6 Signed-off-by: Subbaraman Narayanamurthy <subbaram@codeaurora.org>

Fix it by calling the update function so it gets a chance to vote on not_ok_to_qnovo_votable. Moreover do not return early from ptrain_done handler without setting QNI_PT_VOTER's vote on pt_dis_votable. This is a self clearing bit and unless QNI_PT_VOTER's bit is removed, the next restart may not trickle down to hw.

Adjust the recharge voltage threshold dynamically by lowering it by 200 mV during soft JEITA and charge termination.

This is fine with respect to the algorithm. However with qnovo enabled charging, this can cause issues when charging status can go to not charging intermittently causing the cycle count to be stored multiple times for a bucket. Modify the logic to check for the charge termination or the presence of input to go through all the buckets for storing the count. Also, increment and store the counter only if battery SOC had increased more than 2 LSBs for that SOC bucket. While at it, run cycle_counter algorithm as a function instead of a work. Also, keep the usage of cycle counter feature enable flag inside the cycle counter APIs.

While a battery is charging the TTF should be monotonically decreasing. Track the TTF starting with the first estimate and set hard bounds of -2 and -0.1 on the slope. The negative slope ensures the TTF is monotonically decreasing and the hard bounds on the slope smooth out significant changes in the TTF.

Use this table to calculate the time it will take to charge in each step. The sum of these steps is the total time it will take to fully charge a battery.
