Subject: [PATCH 5/5] ARM: dts: bcm283x: Fix critical trip point
|
|
|
|
During definition of the CPU thermal zone of BCM283x SoC family there was
|
|
a misunderstanding of the meaning "criticial trip point" and the thermal
|
|
throttling range of the VideoCore firmware. The latter one takes effect
|
|
when the core temperature is between 80 and 85 degree celsius. So the
|
|
current critical trip point doesn't make sense, because the
|
|
thermal shutdown appears before the firmware has a chance to throttle the
|
|
ARM core(s).
|
|
|
|
Fix these unwanted shutdowns by increasing the critical trip point
|
|
to a value which shouldn't be reached with working thermal throttling.
|
|
|
|
Fixes: 0fe4d2181cc4 ("ARM: dts: bcm283x: Add CPU thermal zone with 1 trip point")
