Subject: [PATCH v3 0/6] power: supply: introduce support for the Qualcomm smb2 charger

Add a driver for the Qualcomm PMI8998/PM660 Switch-Mode Battery Charger.
This is the second generation SMB charger, and replaces the previous
SMBB hardware found in older PMICs.

This driver provides basic support for initialising the hardware,
configuring the USB input current limit and reporting information about
the state of the charger. Features like type-c dual role support and OTG
switching will be added in future patches.

This patch series depends on my previous series adding support for
the Round Robin ADC which is used for reading the USB voltage and
current, it can be found here:

Changes since v2:
 * Use devm_delayed_work_autocancel
 * Minor driver fixes
 * Pick up Krzysztof's R-b on the DT patch

Changes since v1:
 * Rename the driver to pmi8998_charger
 * Drop unnecessary (and very broken) mutex
 * Rework the driver based on feedback to v1
 * Fix some minor bugs and improve Automatic Input Current Limit support
