Subject: [PATCH 2/2] thermal: rcar_gen3_thermal: Remove temperature bound
Date: Tue, 14 Jan 2020 23:29:45 +0100 [thread overview]
Message-ID: <20200114222945.3128250-3-niklas.soderlund+renesas@ragnatech.se> (raw)
In-Reply-To: <20200114222945.3128250-1-niklas.soderlund+renesas@ragnatech.se>
The hardware manual states that the operation of the sensor is not
guaranteed with temperatures above 125°C, not that the readings are
invalid. Remove the bound check and try to deliver temperature readings
even if we are outside the guaranteed operation range.
