Subject: [PATCH v4 07/32] thermal/drivers/tegra: Switch to new of API
Date:   Mon,  1 Aug 2022 23:22:19 +0200
Message-Id: <20220801212244.1124867-8-daniel.lezcano@linexp.org>
In-Reply-To: <20220801212244.1124867-1-daniel.lezcano@linexp.org>

The thermal OF code has a new API allowing to migrate the OF
initialization to a simpler approach. The ops are no longer device
tree specific and are the generic ones provided by the core code.

Convert the ops to the thermal_zone_device_ops format and use the new
API to register the thermal zone with these generic ops.
