[PATCH 4/5] clocksource/acpi: Add probing infrastructure for ACPI-based clocksources

Show all headers | View raw

DT enjoys a rather nice probing infrastructure for clocksources,
while ACPI is so far stuck into a very distant past.

This patch introduces a declarative API, allowing clocksources
to be self-contained and be called when parsing the GTDT table.
