Subject: [PATCH] arm64: dts: rockchip: add thermal zones information on RK3588
|
|
|
|
This includes the necessary device tree data to allow thermal
|
|
monitoring on RK3588(s) using the on-chip TSADC device, along with
|
|
trip points for automatic thermal management.
|
|
|
|
Each of the CPU clusters (one for the little cores and two for
|
|
the big cores) get a passive cooling trip point at 85C, which
|
|
will trigger DVFS throttling of the respective cluster upon
|
|
reaching a high temperature condition.
|
|
|
|
All zones also have a critical trip point at 115C, which will
|
|
trigger a reset.
