Just raise the interrupt. This avoids undervoltage shutdowns when unplugging the USB PSU from USB keyboard. IP5209 stop supplying power to VOUT during transition from pass-through mode until VOUT boost is enabled. (about 30ms on the oscilloscope) Somehow RK818 doesn't like this when EN_VABT_LOW_SHUT_DOWN is enabled and PMIC shuts down. Emergency shutdown is implemented in keyboard power manager driver.

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.
