| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The master charger has built in Jeita compensation where it reduces FCC when the battery is in cool/warm Jeita threshold. This skews the distribution of FCC between master and slave in parallel configuration. Fix this by checking if soft Jeita is active. If so reduce the requested fcc so that master and slave get reduced share. However, since master is reducing its FCC, add the reduction again to its share so the net FCC on master is as per the distribution. This also calls to handle the battery temperature change interrupt and redistribute FCC.

It could happen that the charger oscillates its VBUS as it settles and based on the delay's in responding to an interrupt, the software could read vbus_present while the regulator was enabled earlier causing an incorrect disable of the dpdm regulator. It is required to ignore the interrupt in such cases. Change-Id: I882780c1bcbc7713973eda5383291d891787f144 Signed-off-by: Abhijeet Dharmapurikar <adharmap@codeaurora.org>

Some of the differences are listed below. - No conventional memory access for accessing SRAM - No OTP region for battery profile - FTRIM registers will be loaded to SRAM - SRAM partitioning and address format got changed completely - Battery id detection done by RR_ADC - Encoding/Decoding changes for battery parameters Hence add a new driver to support this GEN3 FG. This driver reads the battery parameters like voltage, current, temperature, resistance etc. acquired by the FG hardware and expose to the userspace through a power supply class device.

Check if parallel charging is ready once the parallel charger probes so parallel charging can be enabled immediately.

PMI8998 feeds the parallel charger via its MID input, and handles input current limiting in its front-porch FET. As master charger, PMI8998 is responsible for enabling/disabling the parallel charger, and the FCC distribution. To enable parallel charging in software, the following conditions must be met: - Strong USBIN input - Battery present - In fast or taper charging state - Attached UFP source While the enabling/disabling is always under the control of software the disabling can also be done by hardware in case of fault. Battery current is usually fixed to the battery rating. The FCC distribution is simple, a split of 50/50 by default, which can be changed in runtime. When taper irq kicks in, the algorithm reduces parallel FCC by 25%. This puts the charging back in constant current phase until the next one happens where again the algorithm reduces the FCC by 25%. This continues until the parallel FCC drops to 500mA. At that time parallel charging is disabled and master continues charging the rest of constant voltage phase.

Interrupts are controlled by the parent device, and handlers are registered by the SMB138X charger driver. The power supply framework is used to communicate battery and usb properties to userspace and other driver consumers such as fuel gauge and USB. VBUS and VCONN regulators are registered for supporting OTG, and powered Type-C cables respectively.

Using strings instead of integers adds flexibility. - It enables the votable to be shared across multiple drivers without having a common client enum - Debug prints become more useful While at it - remove the use of num_clients in the apis. All of them default to NUM_CLIENTS. - Create a list of all the votables, this allows for searching for a specific votable. - Error if a votable is already created with the same name earlier. - Add debug prints about current clients and effective results - Remove passing in last_client and last_client_id in the callback. These parameters go unused in all the usecases. - Since clients are assigned sequentially and that they cannot unregister from a votable (clients can only disable their votes, but they cannot remove themselves), a null string in the client string array means there are no more clients. Use this to speed up result calculation by stopping at the id with a null string. - Refactor the vote() implementation. Currently the SET_ANY case flows differently than MIN or MAX, make them uniform. - Create an api to call the callback without casting new votes.

* | | qcom-charger: use mutex instead of spinlock when calling the regmap APIHarry Yang2016-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Slow buses regmap holds a mutex lock, while for fast buses regmap holds a spinlock. In order to remain compatible with slow buses spinlocks should not be held before calling the regmap API.

* | | qcom-charger: Don't automatically set USB_PD type when PD_ACTIVE=1Jack Pham2016-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The POWER_SUPPLY_PROP_PD_ACTIVE property is intended to be a flag set whenever the PD PHY is in use. But this includes attempts to establish communication, which may involve trying to perform a hard reset to see if the port partner responds. Thus updating the psy_desc.type field to 'USB_PD' right when PD_ACTIVE=1 is premature as the port partner may not be PD-capable and it could be un-set. Instead allow the PD driver to directly update POWER_SUPPLY_PROP_TYPE only after it is sure PD communication has succeeded.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the new version of bcl peripheral introduced in PMIcobalt. The new support includes, 1. support the new address space 2. set the new Ibat too high threshold 3. set the new vbat low comparator threshold 4. set the new vbat too low comparator threshold 5. enable the LMH DCVSh monitor algorithm, when the thresholds are configured.

* | | qcom-charger: introduce QPNP SMB2 charger driverNicholas Troast2016-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The QPNP SMB2 charger driver supports the charger peripheral present in the PMICOBALT chip. This charger peripheral is common among other chips, therefore the driver uses the smb library to support all common functionality. Register access is provided by the parent device via regmap. Interrupts are controlled by the parent device, and handlers are registered by the QPNP SMB2 charger driver. The power supply framework is used to communicate battery and usb properties to userspace and other driver consumers such as fuel gauge, USB, and USB-PD. VBUS and VCONN regulators are registered for supporting OTG, and powered Type-C cables respectively.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A library of common structures and functions that should be used by all charger drivers that support an SMB charger peripheral. The library includes high level register read/write access, interrupt handlers, voter callbacks, and power supply property getters. It should be extended with any functionality that can be leveraged by an SMB charger peripheral. All drivers that support an SMB charger peripheral should define their own struct smb_charger to interface with the library.

Now that the upgrade is complete we can introduce this commit again. Original commit: commit 8e10bff71301 ("power: move QTI charger drivers to a new sub-directory qcom-charger") QTI charger drivers have outgrown their home in power and deserve their own sub-directory. Move all QTI charger drivers and their dependencies to a new sub-directory of power called qcom-charger.
