BD9573 and BD9576 support set of "protection" interrupts for "fatal" issues. Those lead to SOC reset as PMIC shuts the power outputs. Thus there is no relevant IRQ handling for them. Few "detection" interrupts were added to the BD9576 with the idea that SOC could take some recovery-action before error gets unrecoverable. Add support for over and under voltage detection for Vout1 ... Vout4 and VoutL1. Add over-current detection for VoutS1 and finally a thermal warning (common for all regulators) which alerts 30 C before temperature reaches the thermal shutdown point. This way consumer drivers can build error-recovery mechanisms. Unfortunately the BD9576 interrupt logic was not re-evaluated. IRQs are not designed to be properly acknowleged - and IRQ line is kept active for whole duration of error condition (in comparison to informing only about state change).

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.
