Recently userspace has started switching power_supply class devices with a charge_type psy-property between fast and trickle charge mode, see: https://gitlab.freedesktop.org/hadess/power-profiles-daemon/-/issues/85 Before this patch bq24190_charger_set_charge_type() would unconditionally write charging or none to the BQ24190_REG_POC_CHG_CONFIG bits, replacing the otg setting of those bits when the OTG 5V Vbus boost converter was on, turning the 5V Vbus off, removing the power from any attached peripherals. This fixes this by keeping track of otg_vbus_enabled and the requested charger_type settings and when otg_vbus_enabled is true, delay applying the charger_type until the 5V boost converter is turned off.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
