+Subject: [PATCH 1/4] thermal: imx: Update critical temp threshold
+
+Increase the critical temperature threshold to the datasheet defined
+value according to the temperature grade of the SoC, increasing the
+actual critical temperature value of 5 degrees.
+
+Without this change the emergency shutdown will trigger earlier then
+required affecting applications that are expected to be working on this
+close to the limit, but yet valid, temperature range.
