We modfied the linux-imx/drivers/thermal/imx_thermal.c and chang change the passive and critical trip ponits because the video output will get wrong when the tempture reaching passive point.Is it safe enough to increase passive temperature to105 degree?

-#define IMX_TEMP_PASSIVE        85000
+#define IMX_TEMP_PASSIVE        105000
+#define IMX_TEMP_CRITICAL        110000


Besides,accroding to the "i.MX_Linux_Reference_Manual.pdf", cooling device will lower CPU frequency and notify GPU to run at a lower frequency when reaching passive point.So how can I prevent GPU to run at a lower frequency except changing the trip points?
