Subject: [PATCH v8 11/29] thermal/drivers/uniphier: Use generic thermal_zone_get_trip() function
Date:   Mon,  3 Oct 2022 11:25:44 +0200
Message-Id: <20221003092602.1323944-12-daniel.lezcano@linaro.org>
In-Reply-To: <20221003092602.1323944-1-daniel.lezcano@linaro.org>
References: <20221003092602.1323944-1-daniel.lezcano@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

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.
