+Subject: [PATCH] mediatek: mt7623: fix thermal zone
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Raising the temperatures for passive and active trips. @VA1DER
+proposed at issue 9396 to remove passive trip. This commit relates to
+his suggestion.
+
+Without this patch. the CPU will be throttled all the way down to 98MHz
+if the temperature rises even a degree above the trip point, and it was
+further discovered that if the internal temperature of the device is
+above the first trip point temperature when it boots then it will start
+in a throttled state and even
+$ echo disabled > /sys/class/thermal/thermal_zone0/mode
+will have no effect.
+
+The patch increases the passive trip point and active cooling map. The
+throttling temperature will then be at 77°C and 82°C, which is still a
+low enough temperature for ARM devices to not be in the real danger
+zone, and gives some operational headroom.
