regulator: event: Ensure atomicity for sequence number (2024-01-04 20:02:06 +0000)
----------------------------------------------------------------
regulator: Updates for v6.8
The main updates for this release are around monitoring of regulators,
largely for error handling purposes. We allow the stream of regulator
events to be seen by userspace as netlink events and allow system
integrators to describe individual regulators as system critical with
information on how long the system is expected to last on error. The
system level error handling is very much about best effort problem
mitigation rather than providing something fully robust, the initial
drive was to provide a mechanism for trying to avoid initiating any new
writes to flash once we notice the power going out.
Otherwise it's very quiet, mainly several new Qualcomm devices.
- Support for marking regulators as system critical and providing
information on how long the system might last with those regulators
in a failure state, hooked into the existing critical shutdown error
handling.
- Optional support for generating netlink events for events, there are
use cases for system monitoring UIs and error handling.
- A command line option to leave unused controllable regulators
enabled, useful for debugging. We already only disable regulators we
were explicitly given permission to control.
- Support for Quacomm MP5496, PM8010 and PM8937.
