Subject: [PATCH v1 09/26] thermal/drivers/uniphier: Use generic thermal_zone_get_trip() function
Date:   Fri,  5 Aug 2022 16:57:12 +0200
Message-Id: <20220805145729.2491611-10-daniel.lezcano@linaro.org>

The thermal framework gives the possibility to register the trip
points with the thermal zone. When that is done, no get_trip_* ops are
needed and they can be removed.

Convert ops content logic into generic trip points and register them with the
thermal zone.
